Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

Battery does not want to charge!


You'll need to replace it unfortunately. In the future try not to keep the laptop plugged in when the battery is 100% charged, Once charged unplug the AC adapter. Plug it in only when you need to recharge the battery. Or you can remove the battery completely and only insert it when its needed. Online Virus Removal 39 99 Online Virus Removal and Online PC Help

Battery gets to 8% or so, I plug it in, it says it's charging but warning keeps flashing, screen dims off and on and then it shuts off. Charges fine when it's off. Seemed to work fine before.

Not really, the older NiCad batteries get a memory effect if you keep charging from a half charged state, but modern Lithium batteries do not suffer from this problem.

Hi Ken

A BIOS update can resolve this issue and allow the battery to charge up to 100% in Windows. The BIOS update can be performed either before or after the symptom appears

Will not charge although it can detect it is plugged in


Hi Natasha,

Unfortunately this is a common problem with current Dell laptops. The notebook checks whether or not you are using an official Dell charger, and if not then it refuses to charge the battery even though the laptop will still work. This means that if you are using a third party charger you will only be able to keep doing what you are doing.

If on the other hand it IS an official Dell adaptor then it is possible that the sensor in the adaptor is faulty. Either way if you want your battery to charge you will need to get the right adaptor from Dell.

I don't like the fact that Dell notebook work this way as there are many perfectly good third party adaptors on the market but at the moment there is no other way around this issue.

All the best

I just bought an Averatec laptop battery MFG Part SA23-050170-00, but no instructions came with it and it is Sat and they don't answer til Monday...sob. Do I need to charge it up? and for HOW LONG? ...


Most batteries are shipped and sold with a "staple charge" which is generally 65 to 50 percent, though some OEM laptop batteries shipped with a machine can be 100%

Generally you do want to charge the battery, first you would want to do a full charge for 12 to 16 hours to stabilize the SMART circuits that measure charge capacity. But think of the battery like a body in that it needs regular exercise to stay in shape. Good practices are if you plan on storing the battery for long term, store it at about half capacity, and it will lose roughly 10-15% per month. If you always use the laptop plugged in do NOT keep the battery in the system until you plan to use it portably. 100% for too long can actually make the regulators "forget" what empty is and cause you to shut down when you actually still have some juice left. And although it is good to do an occasional deep discharge, do not let the battery get under 20% often, as this will really be the end of good storage.

Laptop turns off when power cable is taken out even though battery is 100% charged


Hi,
sounds like the system has a problem taking power from the battery, but is able to send power to it for charging purposes, or the battery indicates a ful charge, when in reality it is bad.
If there's a way to borrow a known good battery for testing purposes, you might narrow it down.
I'm sorry, I'd need to see this one to offer any further advice.
Good luck
