5 days ago i open my probook and i think that i had to push more the power button. Usually i work in this lap top without the battery. I turned it off without a problem. Yesterday i triered to turn it on. Impossible. no lights nothing. I tried to turn it on using the battery. Even it was a lot of time uncharged i hope that it would have a little power. Nothing. I must sigh that if i don't work with thiw lap top i unplug from the power.
Somebody can help???????
