It's possibly a hardware problem but you should make sure it isn't a software problem by putting in your system restore cd and restoring the DLL that you deleted, it could be an important system file. If it is a hardware problem, the first thing to try is taking out your memory and sticking it back in place, make sure it's clean and put it in there tight.

My hp laptop dv6305us screen is blank power light is on but screen is totally blank.

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.


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.


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.

It sounds like you have corrupted files in windows, or you have a problem with the hard drive. Remove the hard drive and re-seat it back in place, start up the computer! If no change, use the original recovery disc if you have one and reload the operational system, if that fails have the hard drive tested for bad sectors at the computer repair store.

you killed the laptop with out a UPS and you get a power surge with a dead battery them laptop takes the surge and kills the computer. You can remove the battery and unplug the power supply and hold the power button down for a minute then plug the power back in without the battery and try pushing the power button to see if it comes on if it does your lucky. IF it does not put the battery back in and try again. if There is still no power you have killed the power converter or killed the computer.

HP Pavillion dv6700 - black screen

Do the following without the battery inserted.

Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...

Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.

These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.

Could be a bad memory chip or a hard drive crash. Can you hear the hard drive engage? If so, is there any clicking or dull thunking sounds? Both of these are indicators of a hard drive failure.
