Laptop Refuses To Run on AC

I just got my laptop back from HP support, and they fixed a bunch of problems, but for some reason, when the battery is in the computer and it is plugged in to AC power it will not use the AC power, and the battery will not charge. However, when I turn off the computer, the battery will charge, and when i take out the battery, and turn on the computer, it works fine. This is probably an option problem, but I just don't know where to look, and i can't find anything that will help in the power adjustment options.

 

it might be a bios option, i doubt it, i have had two hp laptops and have never encountered this problem. the power switching from battery to ac and from ac back to battery is a hardware set function. i doubt there is anything in an operating system you can do to change it.

look at the bios, when you first start up the computer look at the splash screen and see what key to press, normally del key or f1 or f2 sometimes f11,

be careful when you are in the bios and don't change anything you don't know what it is!!!!
just look to see if there is an option, i doubt there is.

final note, i would call hp, i have been very disappointed with them lately, their quality control has been horrible.
