Monitor blinks when trying to reboot

monitor is power saving mode
when taking a monitor out of this mode is move the mouse or press keys on the keyboard You can buy a used from eBay for $100 or I would buy a new one for about the same price 24 inch monitors are around $100

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

Sounds as though you have a backlight issue. How old is the monitor?
The keyhole with the lock sign is for a security lock to lock the monitor to a desk so it cannot be stolen.

Plug in the reciever into the computer and make sure the mouse has fresh batteries. Once you are in Windows, press the link button on the receiver. The indicator light should start blinking. Then within two seconds press the link button on the bottom of the mouse, the indicator light should quit blinking. After re-linking the devices move the mouse to see if it moves the cursor. If the cursor does not move, then move the mouse and see if the indicator light on the receiver blinks. If the device does not blink then try re-linking the devices again.

try connecting the usb receiver to a different port might loose or not working properly..

thanks

Hello sir, I have samsung 22in lcd monitor and nvidea fx5500 card. since last more than 6 months, my monitor goes blank If system remains idle (means I don't move mouse and don't touch keyboard) for 1 minute. After monitor goes blank I have to move mouse to brink it back to on. The power led keep on during this problem. I tried everything including power options in windows but could not fix it. Is it bios setting to be checked or could it be windows bug? Please help

the monitor is in sleep mode ... have you tried hitting the keyboard Space bar?

if you disconnect the video cable from the pc does it display ( video disconnected) ? if it does it then is probably the sleep issue

Check cable first

You can TRY to look for cold solder at the board esp popwer section.

Press the link button on the receiver the indicator light should start blinking. Then within two seconds press the link button on the bottom of the mouse, the indicator light should quit blinking.
