Re: Unable to charging when laptop is ON mode

Hi,
there coudl be several reason for this... such as.

1) if the battery is charged for around 90%(depends on model to model it may be 80% also) its normal to avoid anty unwanted charge cycle. this will help improve battery life.



2) if the machine is not charging because to used in too hot ambient temprature or its heating up for some reason. option is to let the machine cool down and it will start charging. this is again technology limitation and safety measure.



3) if above are not true: Try this:

.
Disconnect AC
Shutdown
Remove battery
Connect AC
Startup
Open Device Manager
Click the plus (+) sign next to Batteries category, right-click All of the "Microsoft ACPI Compliant Control Method Battery" listings, and select Uninstall In the "Confirm Device Uninstall" dialog box, click OK. (it’s ok if you only have 1 of these listings).
Click the plus (+) sign next to System Devices.
Right-click the “ACPI Fixed Features Button" and select Uninstall. In the "Confirm Device Uninstall" dialog box, click OK.
Shutdown
Disconnect AC
Insert battery
Connect AC
Startup




hope this helps, Good Luck !
