    I have the same problem.. I've tried new AC adapter. I think the problem is with the internal power supply, possibly the mother board.

Hp pavillion lighitng bolt led on front keeps flashing and will not power on


I see that you said that you "powering on the AC adapter only".
Does that mean you tried booting with the battery removed?
If not, completely remove the battery and try to boot.
If that fails too, it will be a switch or board issue

The power adapter that plugs into the laptop HP DV4000 is broken, and I can't use the charger. where can I find a new one to replace the broken one, or will I have to buy a whold new charger? thanks


Do you mean only the power cable that linked the power brick with laptop was broken? Of course if you are 100% sure that's the only part that fail, you may only buy a cable. Check this link blow:

But if you are not that sure, i'll suggest you buying a whole new charger:

My HP Pavillion DV6000 laptop starts up fine and after a few minutes the screen turns black. I can still see the desktop image in the background but barely. If I reboot the screen looks normal again but...


That means your backlight is going out. The fact that it's happening intermittently like that suggests that you have a faulty screen inverter (a small circuit behind the screen that converts DC power to AC, in order to light the florescent backlight).
I suggest replacing it. Here are some on abay for pretty cheap:

I bought a new ac charger for my hp pavillion dv1000 it will not power on


Check and make sure the Voltage on the AC adapter is the exact same as your previous one. Just because the connector fits in the port, doesn't mean it's the right one. Look in your manual to figure out if your AC adapter voltage is correct. If it is, it's possible that you have a dead battery, it happens when surges happen during power outages. If it's so, look on the HP website for a new replacement battery. It should allow you to type in your pavillion model number.

Battery charging


Does the machine boot and work just on AC?

If it does then you may have a bad battery - Does the old battery charge?

If it does not work on AC then try another AC adapter - even the generic universal kits should be enough to test it.

hopefully that's all thats wrong. let us know.
