Assuming there is nothing wrong with your power connections, which you should check first -- remove battery and unplug unit, disconnect peripherals. Then hold in the power button for at least 60 seconds, reconnect to power source and see if it has reset. No guarnatees but it may reset if it was shutdown due to power surge.

My laptops screen does not come on even though the unit powers up,i have tried another screen,and tried using external monitor,neither worked,the lights by power button also don;t light.


Did you check the power supply? They go bad and if you get no power, nothing else will work. You can check the power supply by plugging the unit into an outlet and then using a volt-ohm meter measuring the voltage at the cylinder which normally plugs into the computer. If there is no voltage (DC) present, then the supply is bad. You can get a replacement online or at the place you purchased the unit.

When power on my laptop it is not working?


Ok, you say when you power up the unit, the power Led comes up an then goes out.?
1st. If you have the battery inserted and the power adapter plugged in and the charging light comes on, showing the battery is charging, the power adapter and battery are most likely OK.
That's not the problem.
2nd. If the unit tries to power up and fails, the best thing you can do is, A. Remove any media in CD/DVD drive. Reove the power adapter and battery,
B. Remove the two covers showing the Hard Drive and Memory. Remove Both H/D and Memory.
C. Disconnect the CMOS Battery, located just above and top right of memory. (Next to Wireless Card). The is a white 2-pin connector.
D. Flip the unit over and press the power button for 15-30 seconds.
3rd. Know you have cleared the CMOS. You will have to re-enter the time and date, once the unit comes back on line.
4th. Reinstall only one piece of memory, Then the CMOS battery and leave the cover off for now.
5ft. Install the battery, Flip the unit over and plug in the A/C adapter.
6st. Look to see if the charging light comes on.
7th. If the charge light comes up, Power up the unit.
The message you should see is Date and Time press F-10 to continue. and then should say, missing Operating system or no disk found.
Remember if the unit will enter the BIOS screen and does not drop off, your in good shape.!
Power off the unit.
8th. Re-install remaining memory and check again. If no problems,
9th. Turn unit off and re-install Hard Drive.
10th. Power on unit and if you have problems, OK., more than likely, its the H/D. and may need to be re-formatted.
If the unit comes up OK, and you suspect the hard drive is at fault, Look for the Hard Drive Test utility in the BIOS screen. (This will smart drive test the hard drive and will take some time, depending upon the size of the drive..)
If you have errors on the drive on the boot partition, you will know soon enough, being the drive has two partition, one in the front of drive and one at the end.
If the drive is OK good deal.
If after trying all the above and the unit still will not power up and run correctly, please respond to this info. and I will run you thru some other things to check.
People please respond to our reply's to for help. If you do not rate us, we are waisting our time to go into detail helping you.
If you feel this information has wasted your time, please call HP and you will come away feeling differently.
Hope this information has been of some kind of help.
Try it, it may work !!
