HP Pavilion dv5-1125nr Black screen with slowly blinking lights

[ Edited ]

HP Pavilion dv5-1125nr Entertainment Notebook with Windows Vista

 

Was working just fine until went to black screen with lights for Caps Lock and scroll/Number Lock slowly blinking. Tried Control/alt/delete, and powered completely down. Do not get an error message and won't start up, just get black screen with slowly flashing lights. The lights just blink in one second intervals, single flash. Help!!!!

As per 1 light blink code sequence which can be found below, it appears your CPU or CPU socket (motherboard) has malfunctioned causing this problem

You need to reflow the solder on the video chip on the motherboard as shown in this video:

I didn't have a torch handy but I took out the motherboard and took the heat sink off and put a double layer of foil on it to protect the heat from getting to other parts of the board and cut a square out of the foil to expose the video chip and put my gas stove on low and held the motherboard about a foot above the flame until I smelled the chemical reaction. I then let it cool for 10 minutes and tested it and presto. Good as new.

I didn't have a heat gun or a gas stove so I used a propane blow torch and it worked.

I faced the same problem. It happened me because I diassembled the laptop to clean the fan, I was facing overheat issue. After cleaning it is just blinking the lights and no display at all...It is because of heat sink and paste

Remove the heat sink and then you can see processor and graphics card chip... Clean it and then check the heat sink paste. If it is dry then apply new paste... Done...

Hi Kamat, my particular problem doesn't appear to be addressed through the link you have helpfully provided. The screen is black and the lights above the caps lock and scroll keys flash simultaneously and intermittently every few seconds without end. Your suggestions would be greatly appreciated.

Hello Crumbs,

 

I see that you are having start up problems with your HP computer. I would like to help with this issue but I need some information.

 

Can you provide the model and product number of your computer? Here is a link that shows how to find that information.

Thanks for the informaiton,

 

I have a couple of troubleshooting documents that may help with your issue.

 

Here is a link to troubleshooting steps for common start up problems. If this link doesn't help then here is a link for troubleshooting blank screen after start up.
