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!

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!
