My HP dv6000 laptop screen goes black suddenly, without warning. It is solid black if on battery power; if I have it plugged in to power supply, it is black with flickering white lines.

If so, I assume that you can't access the BIOS setup screen, yes? Okay, if you can't, it seems that you have hardware problem. By disassembling the laptop, check the connection of the RAM, plug out and in the BIOS battery and carefully check the motherboard for any faulty circuit. But it is always better to leave it to the expert to do those things. ;)

Remove the battery from the computer and plug in the correct charger and see if it will power on. without the battery. if so turn off and put battery back in with power connected see if it powers up.

The DV6000 series of notebooks are known to have problematic motherboards. Try the below options:

1) Hold the power button down for 5 second and the machine should shutdown. Then power on again.

or

2) Flip the laptop over and switch the "lock" switch to "unlock". Then flip the release button to remove the battery for a few seconds. Put the battery back in and try to power the laptop on.

or

3) Power on the notebook like normal. Watch the Hard Drive activity light (the one that looks like 3 stacked plates), if the screen is blank and the activity light is solid or flashing, you know that the LCD screen is bad and needs to be replaced. If that light is not flashing then the problem is your motherboard and it needs to be replaced. Call HP and ask them if your model was part of a DV6000 series recall, if so your repair costs might be covered.

Not it is either the power adaptor or the mother board please remove the battery then wait for 60 secs. and try to turn it on with the power adapter only.

Not for the faint hearted but here's the fix.

They do appear to offer a good repair service a well at what seems a good price.

Thats the first problem of that model.They first dont want to go out of hybernate mode after that the wifi will not work and after that the video of that computer will be dead.I had like 30 HP Pavilion dv6000 and i just hey them nov but i can repair them.!!!

First take out the battery, and run it on AC power alone , if it runs ok its the battery that has died, it you still can run the laptop with orw/o a bttery then the internal power supply has died.

this is a easy one plug up your unit take out ur battery for 30 sec while holding do the power button hit the power button once again and it should come on and if it dont the great things is there a recall on those pc call hp they will send u a new pc free of charge

Hopefully the battery is just confused and needs to be reset. Drain the battery down until the system shuts off automatically, then take the battery out of the laptop for two minutes and plug it back in, and connect the AC adapter, let it charge without turning the laptop on, then turn it on and hopefully it should work fine again. If not then you may need to buy another battery. Try again with another AC adapter just in case because you don't want to replace your battery (expensive!)

Please rate, thanks!

Video chip failure on the main board join the hundreds with the same problem need a new mother \Board and it may still happen again to that one
