AMD isn't leading this crusade out of a sense of altruism. Its real gripe is that MM07 gives Intel, its archrival, an unfair advantage. AMD claims MM07 was created in Intel's labs and rigged so that Intel chips would outscore AMD chips, since AMD chips draw more power when idle. (AMD says that in real-life usage, laptops using its chips perform comparably to Intel's.) AMD also points out that the president of BAPCo happens to be the head of performance benchmarking at Intel.
Intel says this is all hogwash. An Intel spokeswoman says that just because the consortium's president is an Intel exec doesn't mean Intel has special influence. Meanwhile, she can't resist taking a crack at AMD: "You will often find that companies who are behind in performance sometimes challenge independent and standards-based benchmarks," she says via e-mail.Dell Latitude E6400 AC Adapter Dell Latitude E6500 AC Adapter
Intel and AMD are the Bickersons of the computer industry, with AMD always complaining that Intel is cheating, and Intel always responding that AMD should quit being such a crybaby. But lately AMD has been landing some punches. In May, European antitrust regulators smacked Intel with a $1.45 billion fine, Dell Inspiron 5100 Battery, claiming Intel used unfair tactics to bully AMD. (Intel plans to appeal.)
Meanwhile, out in the marketplace, the crazy battery claims persist. Dell says its $2,000 Adamo notebook will run for more than five hours, but The Wall Street Journal got only two hours and 44 minutes. Apple claims eight hours of battery life for its $2,800 17-inch MacBook Pro, but CNET got only four hours and 14 minutes. This stuff is so pervasive that professional reviewers see company-generated battery-life claims as a joke.Dell Inspiron 1100 Battery, Dell Inspiron 5100 BatteryDell Inspiron 600m Battery "The rule of thumb is that in real-world use you get about 50 Dell Inspiron e1505 AC Adapter Dell Inspiron e1705 AC Adapter Dell Latitude E5500 AC Adapter percent of rated battery life," says Mark Wilson, associate editor at Gizmodo. "It's not that companies are lying, but they're stacking the deck in their favor. [Their claims] are misleading to the general public." That's something to keep in mind next time you're out shopping for a laptop.
Laptops score big numbers because they're tested with screens

to 20 to 30 percent of full brightness,Dell Inspiron 1100 Battery, Dell
Inspiron 5100 BatteryDell Inspiron 600m Battery the Wi-Fi turned off
and the main processor chip running at 7.5 percent of capacity—just
like those cars idling downhill. Techies and industry insiders have
long known that official battery-life claims are pretty much worthless.
But regular folks don't. As a result, some are getting pushed toward
pricier machines by sales reps who tell them they'll get an extra hour
of battery life. Those customers may be paying a premium and getting
nothing. "There's only three endings to this story," says Patrick
Moorhead, a marketing vice president at AMD. "Either the industry
regulates itself, or the FTC steps in and regulates us,Dell Inspiron
1100 Battery, or we get hit with a class-action lawsuit. I suggest the
industry go with the first option."Dell Latitude D620 AC Adapter Dell Latitude D630 AC Adapter Dell Latitude d820 AC Adapter
AMD is recommending computer makers adopt a new way of measuring battery life, using two states: "active time" and "resting time," similar to the way cell-phone makers describe the "talk time" and "standby time" of a phone. A Dell executive says that approach makes sense, and that the company is considering providing customers with information beyond the MM07 scores. "Customers expect the advertised battery life to reflect the way they really use the product," says Ketan Pandya, head of AMD-based products at Dell.
Yale and Columbia, some profs have banned laptops from class
altogether. In a more measured approach, the University of Chicago Law
School cut its classroom Wi-Fi signal this spring, citing an
"epidemic" of Web browsing during lectures, while at UCLA law, profs
can activate a "kill switch" to disable Wi-Fi if they sense an
attention deficit. The results, they say, are striking. "I'm getting
much better eye contact," says Michigan law professor Richard
Friedman, who installed a no-laptop policy in January. "It's been like
renewing an acquaintance with an old friend." To others, though, the
crackdown lets the real culprits off the hook. "If you're so boring
that students are zoning out, you ought to rethink if you should be
teaching," says UCLA law professor Stephen Bainbridge—though he admits
that he's flipped the kill switch in his own classroom more than once.

Step
1Place the laptop on a clean and level surface, close to the power outlet you will be using.
Step
2Examine the laptop power cable and identify the end that looks like a
power prong for a power outlet. Dell Inspiron 8500 Battery,Take this
end and plug it into the power outlet you are using.
Step
3Look on the back of the Dell laptop and locate where the laptop power
cable will be plugged in. This will be a small circular hole, about
1/4 inch in diameter. Take the other end of the laptop power cable and
plug it into this hole.
Step
4Charge the Dell laptop
battery by leaving the laptop power cable plugged into the power
outlet and Dell laptop.Dell Latitude D800 Battery, Dell Inspiron 8500
Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Time to fully
charge a battery will vary, based on the amount of power the battery
currently has.Dell Inspiron 1501 AC Adapter Dell Inspiron 6000 AC Adapter Dell Inspiron 600m AC Adapter
Step
5Check the power level of your laptop battery by carefully lifting up
your Dell laptop and pressing the button on the bottom of the Dell
laptop, which displays a battery icon. Zero to six green lights will
display, showing the current power level of the laptop battery. Dell
Inspiron 8600 Battery, This shows a range of power from zero lights,
meaning empty, to six lights, meaning full.
Here's what happens: The battery is not really dead,Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, but it looks to me like some electronics inside of the battery are preventing the battery from charging. When I click on the battery indicator I get a funky blinking light and when inserted into the computer the the charge light just blinks orange instead of the regular green charging indicator. Did I mention the battery was working just fine a few days earlier with a charge hold well over 3 hours of work time.
This seems like such a rip off if you ask me. I started calling tech support to see if I could get a warranty on the battery. Of course the warranty had expired exacly two weeks ago, and there was no budging the Dell support guy. FWIW, Dell doesn't warranty batteries that are older than a year even if you have an extended warranty for the rest of the system. Dell Inspiron 9300 AC Adapter Dell Inspiron 9400 AC Adapter
Next I went to the Web Site to see what a new battery would cost and sure enough there's some language that says it's rated for 300 charge/discharges. Now I would really be curious how this is measured. I'm pretty sure this battery isn't actually dead, but something has been quietly counting roughly how the batteries been charged and decided - dup, that's enough for you buddy. So now I can't even use that battery as a hold over battery while the system is plugged in (I like to use the battery as a UPS since we loose power on a regular basis here on Maui).
At $199 list this isn't a game I like to play.
The worst part about this is that I rarely use the battery anyway. Sure when I travel I use the laptop on the plain or around a client's office,Dell Inspiron 640m Battery, but for the most part the machine is plugged in and under power. But even when it is - according to Dell the battery is discharged/recharged. If there's electronics in the damn battery shouldn't it be smart enough to figure out that while it's under power it should not engage the battery in any way at all?
It really eats at me that we get reamed by so many companies any way they can get you.Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Always stick it to you in the details. There are a couple of other things that happened today that go along with that but I'll leave that for yet another rant ...

The
tech revolution at the nation's top law and business schools, where
students now routinely use laptops and wireless connections in class,
has created an insurgent population: professors, who believe they're

Safety of battery
● Do not short-circuit the battery. Short circuit leads to serious damage to the battery.Dell
INSPIRON 1000 AC Adapter Dell
INSPIRON 1300 AC Adapter
● Do not let the battery fall or knock or misuse the battery for fear of
exposing the corrosive substance inside the electric cell.
● Do not expose the battery near a heat source, a moist place or a rainy place.
● Do not burn batteries. Keep the battery far away from the fire source
and other extreme heat sources. Exposing the battery in an extreme heat
source may lead to explosion.
● Do not attempt to dissolve, repair or alter the battery set because
this may lead to overheat and combustion of the battery. Do not pierce
the battery with a pointy object.
■ Quick Q&A:
1. Question: How long can a new battery drive the computer?
Answer: It is difficult to determine the operation time of the laptop
battery. The actual operation time depends on how much electricity is
required by the device. The screen size, hard disk and other accessories
may consume extra electricity and shorten the operation time. The total
operation time of the battery also depends on the design of the device.
Generally, a battery of a standard volume is designed to drive the
computer for more than two hours.
2. Question: Why is the electricity reduced before the battery is put into use?

Answer: Due to influence of ambient humidity and non-insulated
environment, the battery is consumed naturally. Depending on the newness
and quality of the battery, Dell Inspiron E1505 Batterythe electricity of the battery is reduced by about 1% in 3-4 days. Therefore, a moderate reduction of electricity is normal.
3. Question: Do I have to remove the battery when I use the AC supply?
Answer: Generally, the charging of a laptop battery begins only when the
electricity volume is lower than 95%. Due to existence of natural
consumption, the battery consumption is basically the same no matter
whether you remove the battery or not while the computer is working.
However, we recommend you not to remove the battery while operating the
computer because this prevents the data loss in case of abrupt
interruption of the AC supply. If you remove the battery, wrap it into a
fresh keeping film and put in a dry and cool place. Remember to perform
a complete charging and discharging cycle for the battery every month
to prevent the battery from losing activity.
4. Question: Is the battery life reduced if the battery is charged before being exhausted?
Answer: The calculation of the battery life is based on complete cycles
of charging and discharging. The life of this kind of Li-ion battery can
read 10,00 cycles. You do not need to worry whether the battery is
charged for a cycle once the AC supply is connected. Only a complete
cycle of charging or discharging counts is as a cycle when calculating
the battery life.
5. The electricity volume is still displayed as 0% after my battery has
been charged for 20 hours; and the computer is powered off immediately
after the AC supply is interrupted. Why? HP Pavilion DV6

Answer: First, check whether the battery contacts the laptop
properly.Dell Inspiron 1000 Battery, Dell Inspiron 2200 Battery Dell
Inspiron 6400 Battery, Dell Inspiron E1505 Battery, Improper contact
makes it impossible to charge the battery even if the communication data
of the battery is readable. In this case, try to unplug and plug the
battery for more times. If you hear a clatter after inserting the
battery into the laptop, it is generally regarded as proper contact. Try
inserting for more times, and you will know whether the laptop contacts
the battery properly. Pay attention to this especially when you use an
IBM laptop. If you are sure that the battery contacts the laptop
properly but the battery still does not work normally, the battery may
be substandard. Dell Inspiron 1000 Battery
This problem is caused by two factors: (1) The line board of the
battery is damaged or short-circuited; (2) the battery may be
incompatible with your laptop, which is a technical problem and needs to
be solved by us. Please contact distributor to check the status of the
battery.
6. Question: The battery does not work and the laptop powers off
immediately after I disconnect the AC supply when the battery is charged
to a certain percentage or even 100%. Why?
Answer: When this problem occurs, check whether the ambient temperature
is too high. If the laptop is used in a high-temperature environment for
a long period, the battery will be disconnected for purpose of
protection. In this case, in order to prevent accidents, shut down the
laptop first, take out the battery, and then reload the battery. Another
possibility is that your computer is faulty in the process of charging.
In this case, check the computer because the charging circuit of the
computer tends to fail in case of charging. In this case, use the
original battery instead and check whether the computer works normally.
If the problem persists, contact our distributor to replace the battery.
7. Question: My Dell laptop does not identify the battery and displays
"the battery is not compatible with this computer, please insert Dell
battery", with the indicator blinking. Why?

Answer: This information tells that the battery is not compatible. In
this case, contact your distributor to replace the battery. Feed back
the information to our suppliers so that we can improve and enhance the
battery compatibleness in time.
8. Question: When I put the battery into the computer, the computer
shuts down automatically; when I take the battery out, the computer
works normally. Why?
Answer: That indicates the battery is faulty. That occurs rarely and is
possibly caused by technical faults arising from short-circuit
protection of the battery interface. In this case, contact your
distributor to replace the battery.
9. Question: My battery makes the computer shut down directly without
alerting or changing into the hibernation status. This occurs for
several times in a few minutes after the battery is charged to full.
Why?
Answer: Operate according to "Calibrate your laptop battery to optimize
its performance" described herein above. If the problem persists,
consult the local distributor.
10. Question: The battery volume is displayed as 30% after the battery
is initially charged for several hours. Why? How can I charge the
battery to 100%?
Answer: Operate according to "Calibrate your laptop battery to optimize its performance" described above. Dell Inspiron 2200 Battery, If the problem persists, consult the local distributor.
11. Question: Why does the computer display completion of charging only 10 minutes after start of initial charging the battery?

This a common problem for all recent Dell laptop models. I have a
Inspiron 1501 and the same thing happened to my battery. When I bough my
laptop I was offered a great deal on a second battery so I bough one
as a back up. Since the laptop only takes one battery at a time I only
took the second battery with me on long trips. Even though the seconds
battery only got occasional BOTH batteries died within days of each
other and both mere days after I had them for 1 year. I find it odd that
BOTH batteries would die at the same time. If you do a search for the
terms DELL BATTERY NOT RECOGNIZED you'll see that a lot of other Dell
laptop users are finding that they Dell batteries are dying at the 1
year mark.Dell 1691P Battery, Dell 75UYF Battery, Dell 5081P Battery
Dell 6T473 Battery There is a work around that proves that these
batteries still have a lot of life left even tho the BIOS says that they
are dead. This makes me think that either there is a bug in
electronics on the battery that monitors the battery health or Dell
intensionally built a 1 year death switch in to the batteries. Which
ever the case is Dell needs to correct this situation.DELL Inspiron 630m adapter DELL Inspiron 6400 adapter
I've recently hit the year and half mark with my Dell laptop and I'm running in to problems with my AC adapter.Dell 5081P Battery The laptop doesn't recognize it and the laptop won't allow it to allow my new battery to charge! If I want be able to change my laptop battery I need to buy another AC adapter from Dell as third party adapters won't be recognized. A new Dell AC power adapter is only $70 but feel like I am being nickel and dimed to death by Dell. It would be one thing if these parts were broken and no longer worked but they still work! They just aren't being recognized.
This is the very last laptop I buy from Dell and my very well be the very last computer that I buy from them. The next time thing anything isn't recognized on this laptop I am going to part it out on eBay! Hopefully by parting out my laptop other Dell laptop owners will be able to get a little more life out of their laptop without having to pay Dell to be able to use their own laptop for another year.
Don't skimp on your battery. If you
choose the lowest-cost battery you'll probably get a battery that
degrades quickly, and you'll end up buying a replacement too soon
anyway. So spend the money now to save expense and frustration down the
road.
Don't buy an expired battery. A good indicator of a battery's
performance is how far into its product life it is, whether it's used
or new. If possible, look at the bottom of the battery and find the
manufacture date.DELL Inspiron 6000 adapter DELL Inspiron 600m adapter
We just reviewed a new retail-specific version of Dell's popular
Inspiron 1525 laptop, and found ourselves wondering why this new
system's battery life was so poor compared to its very recent (and
largely identical) predecessor. How can two versions of essentially the
same laptop have a difference in battery life as big as the 3-hour vs.
2-hour one we found? We looked a little closer and found a potential
culprit.
weather it's weak or not a well batt do this,Dell 1691P Battery, you
can charge the batt for a hour, use it for a few minutes, then take it
apart, and measure the voltage across each set , when you find lower
voltage in one set out of all the sets, those 2 need to be replaced,
and them the batt shoud last another year till the next set goes.
the outline is that not "all the cells go bad at the same time", Dell 1691P Battery, Dell 75UYF Battery, Dell 5081P Battery Dell 6T473 Batteryit only take a weak cell in the chain or series set for the batt to be not useable and then the whole batt looks or seem dead DELL Inspiron 1300 adapter DELL Inspiron 1501 adapter
order some 18650 cells w/ tabs at 2300ma x 2 as a set = there 4.4 amp batt.
laptop batts are made to drain at 1300 ma MAX. for each 18650 cell, in parral
of course its easyier to find a weak cell if the whole batt is under a small load, this goes for any multicell series battery. you might try a 25 watt christmas tree bulb to make a load after you find the red + and the blk - main output of the apart batt, the light doesn't glow sence it's a 120v bulb, will just gives the regular comsumer away of getting a load to make finding the weak pair easyier.
Take Care, and be careful not to draw more than 1300ma out of the batt under the load, do this at your own risk, but this will save you alot of $$ if you get good at it, a 25 watt bulb should draw about 400 ma. out of the batt while your on the meter moving and comparing the sets of batts, you should see a big difference when you find the bad set.
replacements are on ebay for about $5 each , get the tab ones, solder the new ones in and charge over night and you sould be in good shape if you replaced the correct set.
it would cost you much more that $45 to replace all of them if you had a 14.8 v batt, 6 of them if you have a 11.1 laptop batt, with 2300ma high output cells each,Dell 75UYF Battery, try the 2200ma ones first, there cheaper and good for the first experiment.DELL Inspiron 9200 adapter DELL Inspiron 9300 adapter DELL Inspiron 9400 adapter
all sellers and manufacturers LIE about their products, a 2200ma batt is really a 1800ma one, ect. only 1 batt out of 10,000 made can achive their advertized spec. if there lucky.
Finally, I've got three AC/DC power adapters and they all work to boot up and run the laptop but none of them will recharge my batteries. I've got three batteries too, two give the amber/green blinking lights and one just sits there not re-charging with 0% charge. Which leads me to Motherboards!
Motherboards:DELL Latitude d830 adapter DELL PA-10 adapter
In general this is not where your problem lies...despite what Dell may tell you!
Usually if you replace your battery and your AC/DC power adapter the
problem will be resolved. That said...it's not always the case:
Some people have had problems with power jacks..Dell G5266 Battery..go see a specialist
Personnally I stripped myDell Inspiron 8500 (yeah, I know it's ancient!) down to it's bare bones to get at the mother board (Good service/maintenancemanual at the Dell site). I found a regular mayfly nest centred on my AC/DC power adapter jack. All the soldering connections looked good and I had no wobble of the jack. I cleared out all the detritus using a 1/2" paint brush, sprayed some WD40 around the contacts and re-assembled the machine with high hopes!
No change: all my batteries (3) still blink at me and all my adapters (3) are unreconised by the BIOS despite being on the latest version.
Guess the Mayflies finally got the better of me and shorted my re-charging connection on the AC/DC power adapter/charger jack on the MoBo.
So pi**ed off! All I want is a program that will override Dells imbecilic requirement to have a battery installed to run the CPU at full throttle HP Pavilion ZV6000 adapter HP Pavilion DV6000 adapter
And yes, I've got my power configuration to 'Always On'!
I WANT FULL CPU THROTTLE WITH NO BATTERY INSTALLED
Well, from what I understand about L-Ion batteries, heat kills them. I
have a Dell e1705 and I bought the 80Whr battery figuring it would be
useable longer. Wrong! 12.5 months later and battery is dead. I
understand that L-Ion's loose capacity, typically 20% per year
(according to Wiki info and such) but didn't know that HEAT can increase
this rate! Hmmm...so storing the battery in the laptop, which get's
quite toasty is probably the cause! Also, not widely publicized, but
L-Ion's start losing capacity the day they are made, so if you get an
older battery pack, even new,Dell D5318 Battery, Dell G5260 Battery,
Dell G5266 Battery Dell F5136 Battery, it has already started to go bad.
Perhaps we need to fight for a freshness date to be supplied with all
batteries? I just purchased a new battery and plan to only put it in
the laptop when needed. We'll see if this allows it to last longer or
not. Also, don't leave the laptop (and battery) in your car during the
summer and winter. Dell F5136 Battery The extreme heat and cold can
also damage or degrade the battery. I also plan on calling warranty
support in month 11.5 on this one as I'm quite sure it's "capacity"
will report as low.DELL latitude E6400 adapter DELL latitude E6500 adapter
Ripping open the old battery revealed 9 x 18650 sized cyl cells, so I may attempt a refurb on this one. If it fails, I'll at least have a light weight, plastic blank to fill the hole in the laptop while my battery sits safely in my laptop bag.
when you depress the battery test button on the back of your Dell Li-on battery,Dell D5318 Battery, you get a light, then your battery is probably okay...just low on chargeDELL Latitude d600 adapter DELL Latitude d820 adapter
If you get no light at all your battery is probably knackered. Dell D5318 Battery, Dell G5260 Battery, Dell G5266 Battery Dell F5136 Battery,If inserted it will result in the amber (3) and green (1) flashing battery recharge light.
Pressing the battery health indicator button for 15-30 seconds may or may not do nothing (in my case nothing)
Putting the battery in the freezer for 30 minutes did nothing for my battery except get it cold and make it wet. Can't be good!
If your battery is flat, you can't flash your BIOS (needs 35% charge on battery and on AC to flash BIOS).
If your battery is flat or not installed, your CPU speed will be reduced to 50% of your CPU capacity ( i.e. Intel P4 2.4MHz will only operate at 1.2MHz) and there's nothing you can do about it! You can't overclock it and you can't re-raise the FSB multiplier.
(As an aside..... why does Dell do this? If I'm on AC I don't give a frig about my batteries yet the system still runs at 50% CPU capacity.....this is ludicrous!).
AC/DC power adapter and charger:DELL XPS M140 adapter DELL latitude E5500 adapter
This is a sensitive and important bit of kit. The pin in the middle of the power plug that goes into the back of your laptop is responsible for recharging your batteries. Dell G5260 Battery,If this is damaged (bent, bust off or too short) you will not be able to re-charge your batteries. (A likely cause of the unrecognised power adapter error message at boot up).
In addition Dell recommend you to test your recharger: don't use a multi-tester to test voltage or ampage as the probabilty of you touching the middle pin and the +ve terminal is high and you will blow the EPROM chip in the power adapter/recharger rendering your charge unable to charge! Use another Dell compatible machine!
If your power supply is flakey (i.e. it's going through a 4-way power point adapter and on an overloaded convenience outlet electrical loop) the laptop may not re-charge; it needs a good 10 seconds of good current before it will attempt to recharge the battery.Dell D5318 Battery, Dell G5260 Battery, Dell G5266 Battery Dell F5136 Battery, Solution; plug the laptop power adapter directly into the wall - no multiple power sockets!
Dell laptops will not recognise other brand 'compatible' AC/DC power adapters/chargers and will not re-charge from them. Don't use them!
