Please get and test your Display chipset this causes that problem as you walkthrough the steps of how BIOS works. It stops from the execution of the program written to test the functionality of the output which is your DISPLAY or LCD screen or PRN.

This might cost you around RM200 bucks.

    It is the same story. I already done that kind of problem! Some told that the bios,ram,hd is the problem but that's all is not correct. the truth is the GPU priority the Problem. I already reheated the GPU and its back again. that's the good idea.

I have a compaq Presario cq40-215wm wil not boot screen stays black. light by caps lock and num lock blink 1 time over and over. Got the same result with a hard boot


Have you tried removing the battery, and disconnecting the power adapter. If you have not tried that please try that.
1. Once you have removed both. 2. Power up computer with just power adapter connected and no battery. 3. If the computer powers up shut computer back down 4. Put battery back in and leave power connected
If that does not fix the issue. The back light has possibly gone out on the computer. Depending on how old the computer is. 1. Either contact the manufacturer of the computer 2. Take computer to a repair shop 3. Consider purchasing a new computer

Compaq 6735s notebook pc goes to HP screen, but wont boot


Hi,

First you need to determine how many blinks you are getting when you try to power on the laptop.
Check the blinking codes below and reason behind that for HP Compaq laptops

Blinking battery power LED Battery Insufficient charge on the battery
Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional
Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure
Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional
Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional
Blink: 5 - Caps Lock/Num Lock - System board General system board failure
Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure

Plz get back so I can suggest you the steps to resolve the issue.
