Emachines charging


I've gone through exactly what your're going through right now.
I'm sorry to say but your battery is dead, you need to get it replaced. It can be replaced under warranty, if you have it.

To avoid this kind of a problem in future take care that you:
1. Don't let the battery drain out after your PC warns about low battery.
2. Try to maintain it's charge when you are not using it for days. The self discharge of the battery may take it below the critical level even when you're not using it. So keep charging it even when you're not using it.
3. Preferably use your laptop on external power supply (keep it on charging while using it whenever possible), charging it even when the battery is full doesn't hurt.
4. Let it have a charging and discharging cycle at least once in two weeks.

The above steps will help you maintain a good health of your battery and avoid the problem you're in currently.

Hi,

This sounds like the laptop is faulty if within minutes the laptop is totally drained of power from a so-called full charge.
Because the laptop is new then I recommend that you send or take the laptop back for repair or replacement as it's still covered by the manufacturers warranty.




Regards.

Won't start - battery critically low


You should have a light on the notebook indicating that the power supply is plugged in (this should come on with or without the laptop being turned on). My acer has a green light for power, and the battery indicator shows amber for charging and green for full. If you are not seeing the power or charging indicators, you either have a damaged power jack, or a damaged power supply. Power supplies can be purchased usually for fairly cheap online, but if your power jack is damaged, the laptop will have to be serviced by a service center, or by someone who is skilled with a soldering iron and the disassembly and reassembly of laptops.

Critical battery warning despite directly plugged to AC


1. Your battery is on its deathbed and no amount of charging will help. You might be able to keep it working a little bit longer by completely draining it and then completely charging it.
2. There is a problem with your laptop's motherboard where it is giving incorrect signals about the status of the battery. In this case you will need to consider a new motherboard.
3. If it is just showing up as minimum battery on your OS but you are still able to use your laptop for more than a minute then it might just be a problem with the software controlling the battery power on windows and in this case you will need to fix the problem with the software, not the hardware. In this case, you will probably want to find out if there is a BIOS update or a patch for your particular computer that resolves this issue.
