Battery Trouble

Last night I was using my Aspire Timeline 581TZ-4657 laptop. Without warning my laptop shut off. Even though the AC was supposedly plugged in according to Windows 7. Upon further discovery it turns I didnt plugged in my AC power all the way in the laptop. In reality my laptop was running on battery, Windows 7 said it was charging and running AC power.

Now my laptop wont run on battery anymore. It doesnt turn on or even charge on battery mode. When I use the AC power cord Windows 7 says the battery is "90% available (plugged in, not charging)"

The Acer laptop also displays a blue light. The blue light indicates the battery is fully charged.

I've tried: Removing the battery and placing it back in, Uninstalling and reinstalling "Microsoft
ACPI-Compliant Control Method battery"

Im out of ideas??

 

Did you try booting without battery then shut-down then put battery back and boot again with battery in? Also is the battery light on when laptop is shut-down and plugged in? May be you could try leaving laptop plugged in when shut down for few hours...

I had similar issue: It was showing that battery is in but it didn`t detect battery capacity with message 0% full, plugged in not charging...

And I tried with combinations above and somehow it worked - really don`t know which step made it work...

Hope it will help...

Cheers

 

When I shut off the laptop with the AC Plugged in it displays a blue light meaning its fully charged.

Booting and Shutting down without the battery did nothing as well.

 

What happens when you plug out charger when in windows to make it go on battery?

 

The laptop shuts off immediately.

 

Then definitely your battery is dead and you should replace it...
But before you do replace it, I would advise you to check battery capacity by using HWMonitor. At the bottom you will see following: Designed capacity and last charge capacity. If the later is much much lower than the first one then your battery has reached is "funeral"...

P.S. Sorry for late response...
