Black screen on Hp compaq 615

[Bino_84]

Hello, I have a problem with my laptop hp compaq 615. It was working fine and suddenly when i wanted to turn it on i get a black screen. It starts fine i hear a cooler, then stops and nothing on display shows. I was looking accross the web for my solution and didn't find any so am posting here. There are only 2 lights one for power button and one for wireless/bluetooth button. W/B button is blinking all the time orange to blue. Capslock button isn't blinking which I found out that it shows light codes if something went wrong with memory, proc, hard etc. I removed a memory to check if maybe the light isn't working on capslock. After i started the laptop without memory i get same black screen, capslock is blinking 3 times in a row that indicates that something is wrong with the memory, but W/B button isn't blinking in that situtation. I put the memory back and i get same result, blinking W/B button and black screen. If I may add the feeling that i get when starting up the laptop is it stops starting up when W/B button starts to blink.

So I think if W/B button is blinking, maybe wireless card has gone wrong and needs changing??? But its silly that laptop won't start because of that.....

Hi Bino_84,

Welcome to the HP Forums! You hear the fans turn on and stop and nothing shows up on the display. So does it say blank the entire or something comes up and then goes black? It is going to be hard to diagnose this problem without getting it to turn on at all. How long have you had the notebook for?

Try doing a power reset. Remove both battery and the power cord. With them disconnected, hold down the power button for 30 seconds, this will disperse any remaining or flea energy. Then try the battery first and if that doesn't work do both battery and power cord.

In case it becomes relevant what is your operating system?

Thank you,

Thx for the welcome! 😄

I have the laptop for about 2-3 years, problem occured just recently.

Screen is always blank and same result if I plug it to another monitor.

Done the power reset many times no effect.

Just got memory from another laptop replaced it same result so i think memory is fine, checked hard on desktop PC works fine. Replaced wireless card same result.

So if the caps lock isn't blinking one time i think processor is fine too.

Only thing that i think is not working properly is graphic processor or mainboard has passed out.

Personal opinion is that I think GPU is the problem.

I found this solution http://www.dailymotion.com/video/xc4bdy_hp-pavilion-dv6000-blank-screen-vid_tech

Maybe it will work to burn it than leave it to cool of to reasamble???

P.S. operating system is Windows 7 but i think that has nothing do with this problem.

Hi Bino_84,

If you have tried another monitor is does sound like a GPU issue. Without the computer turning on we are not going to be able to test anything. With the computer being out of warranty you can give that dailymotion video a try. I have heard before that this may resolve the issue. Obviously, I can't guarantee that it work but it looks like your best bet.

Thank you,

Hi, I have a similar problem. Turned laptop on, fan starts but nothing happens on the screen. Caps lock light flashes four times. Laptop is about six years old so well out of warranty but would like to get it working so I can at least access what's on there before replacing. Any help gratefully received.
