Hi eslamsoly,

Well thank you for answering back. Youve mentioned that the caps lock key flashes. How frequent? After pressing the power button of the machine or after the machine boots but shows nothing on the screen?

Can you try this steps.

Perform hard reset (Thats number 4 according to what you did before reaching us..)

Maybe youve done it the wrong way so heres how.

•Turn the NB (Notebook) off if the state is currently turned on

•Unplug the AC charger from the computer

•Unplug the battery (if possible)

•Press and hold the power button for 30 secs without the battery and charger connected

•Plug the AC charger to the computer without the battery and turn it back on

•OBSERVE..

If the computer boots then update the bios of the computer

If the computer doesnt boot then try the Bios combination key.

BIOS combination key

1.            Turn off the computer.

2.            Plug the notebook into a power source using the power adapter.

3.            Press and hold the Windows key and the B key at the same time while the computer is off.

4.            Still pressing the Windows and B keys, press and hold down the Power button on the notebook for 1 second, and then release the Power button and the keys.

The Power LED light remains on, and the screen remains blank for 30 to 60 seconds. You might hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS updates automatically.

If the HP BIOS Update screen displays, continue to step 5.

If the HP BIOS Update screen does not display, find your condition from the following options and then follow the steps for that condition:

•              Computer boots into Windows

If your computer is able to boot into Windows, update the BIOS to the latest version using the standard BIOS update procedure as per the HP support document: Updating the BIOS (Notebooks)

•              Power LED light turns off

The computer turns off if you press and hold the power button too long. Repeat steps 1 through 4 above, this time press and hold the power button down for between one to three seconds in step 4.

•              After repeated attempts, the HP BIOS Update screen does not open

Your computer does not support this function or it has a hardware problem that is preventing the tool from opening. Contact HP Support for further assistance.

5.            After the BIOS is recovered, a Continue Startup button displays and a timer counts down. Click the Continue Startup button to restart the computer immediately. The computer restarts automatically when the timer reaches zero.

6.            When the computer restarts, a message similar to the following displays: A system BIOS Recovery has occurred. BIOS Recovery (500) Enter – Continue.

Press the Enter key to continue immediately or to allow the computer to reboot automatically.

NOTE: After restoring the BIOS, if the computer repeatedly displays a message that the BIOS has been recovered, perform the steps in the HP support document: HP BIOS Application Selected Is Corrupt or Missing.

7.            After restarting, Windows might display a message stating that the computer was improperly shut down or that a boot problem was detected. Read and respond to the screens to continue
