The battery bars indicator at the top of the screen will be full and when fully charged the message will say battery fully charged, if you unplug the charger and reconnect and the battery is fully charged you will see this message!

First, you should know your battery is a Ni-CD / NI-Mh or Li-ion battery. If it is a Ni-CD / NI-Mh battery, please fully discharged and fully charged it to prevent "Memory effect".

If it is a Li-ion battery, please charge it before you use it.

Please keep in mind that, please fully charge a battery when you store it. And, charge it again every two months.

If your old battery is dead, you can replace it with a new one. Ryobi Power Tool Battery

with laptop batteries its recommended that you charge it fully the first time and let it drain completely then charge it fully again and unplug it. you will do damage to your battery if its fully charged while its still plugged in and with all rechargeable batteries they decrease how long they can be used over time.

please let me know if this helped

When the amp meter reads 0, then it is no longer drawing amps and is fully charged.

i hope this was helpful,

This is about Gateway M275 battery not chargering problem.

Hook up only the ac adapter to the DS to see if it turns on. If it does then we know the ac adapter works. We know the battery got fully charged but the system isn't turning on with the battery that is fully charged up.

I would say your battery is defective but you won't really know until you fully charge up a known good working battery and test it out.

thier is a pic of a batterty in the bottom right corner, it will be fully green when charged. otherwise it will be flashing.

When batteries are placed into the charge mode, the red light will come on.
When fully charged, on those units with a green light, the green light will be an indication that your batteries are charged and if your unit has no green light, the fully charged indication will be when the red light turns iff.

Synchronize your E2, then work on draining the battery all the way down in order to reduce the effect of battery memory. Memory happens when we repeatedly partially charge a battery. Over time the battery will forget how to keep a full charge, but will remember how to be partially charged. That's usually when users realize there's a problem. The first step is to drain the battery and FULLY charge it at least fully on the battery's indicator, but if you can, let it sit for 24hrs. The second step is to try to use the battery more before charging it and let it charge fully (ie-overnight) before using it when you need to charge it.

Good luck and let me know how you make out.
