My notebook shows no sign of power


Remove battery turn the notebook on, does it works?
press the battery back in place, is there any lock on backside op the notebook?

is there any signs of charging? flashing led or so?
if not the internal plug to the power supply could be damaged.

Screen goes black after windows XP logo, then no response.


I would suggest checking your hard drive to see whether or not it has a bad sector on it.

The laptop doesn't boot up always.


I would try the following:
1. Remove the battery completely. If the computer boots properly several times in a row, then the battery may be causing the power supply to do strange things.
2. If you have experience removing laptop components, try removing the hard drive. Because you say the screen goes black (I assume the system powers off) sometimes after the HP logo, I doubt its Windows or a software issue.
3. If HP has a diagnostic CD you can boot to, try that.
4. It may be the power supply acting up. If it charges the battery, and if you can boot to Windows with the battery, try getting a new power supply.
5. Otherwise, it may be the motherboard of the laptop.
