I opened the notebook and tested the power cable, which is OK; over the motherboard everything seems to be OK:no burnt or damaged componets, leakage capacitors. I tested the AC adapter which is also OK. Is there a problem with the batery? How can I test it? Some is wrong with hibernation mode? How can I maka a heavytest of the AC adapter?
Bu iyi bir soru mu?

Sully Kubillas, the service manual for your computer is available at http://bizsupport2.austin.hp.com/bc/docs... Check the flowchart for the "No Power" problem. It will guide you through the individual steps. One of the recommendations is that you should perform a hard reset as the first procedure.
Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
you might also want to take a multimeter and see what your battery shows and also check your DC adapter on the motherboard to make sure that it is making proper contact. . Good Luck and I hope that this will help to get you started.
