HP Pavilion DV3 ( Scroll & Caps Lock LED's blinking four times + Blank Screen )

[ZeeAlAlawi]

Hi,

I have an HP Pavilion DV3-2157cl
When I press the power button, the screen remains blank. Also, the scroll & the Caps Lock buttons keep blinking four times.

Sometimes, the laptop works like nothing's wrong but Most of the time, it remains blank with the blinking lights!

Can anyone help me?

remove the battery, other peripherals and the AC adapter... press and hold the power button for 20 seconds... plug the AC adapter only and turn on the notebook....

thank you for your reply.

i have tried this twice but i still have the same issue.

are there any other possible solutions?

1. Disconnect all the peripherals and the battery and try to start the notebook with the AC adapter only.
2. Please try to start the notebook without the hard drive.
3. Please try to start the notebook without the RAM.
4. Please try to start the notebook by swapping the RAM Chips (one chip at a time or exchanging the slot)
5. Try to connect an external monitor.

I have tried all the solutions.

For solutions #1 and 2, the LED light still blinked FOUR times.

For solution #3,the LED light just blinked THREE times.

For solution #4, the LED light just blinked FOUR times.

For solution #5, the LED light just blinked FOUR times.

As I've read in the HP site.

Blank Screen LED Error Codes

http://support.hp.com/us-en/document/c01443366

LEDs blink 3 times-----Memory--------Module error not functional

LEDs blink 4 times-----Graphics-------Graphics controller not functional

Do you know what that means and what can I do to prevent the issue I stated in the beginning from ever happening again?

I have the same problem here. I've tried all those solutions, and I get the same results 😞

Did you ever solved this issue with your HP? can I hear more about it?

Thanks in advance!

i had a problem with my dv3 (blank screen keeps flashing) and used this method to reflow the graphics card/chip (see link below).  only try this method if you are at your wits end... and you are skilled with taking apart/putting together electronics.  it will take you a minimum of 1 hour (but most likely, about 2).  you will need a heat gun (about $10 - $20).

to prevent it from continually over heating, you can try the penny mod (google it).  that's what i did.  you basically take a penny and sand off both sides until it is the right thickness and solder it onto the heatsink.  you'll need to remove the sticky blue foam that HP used instead.

i also noticed that a laptop cooler placed under your laptop works well for keeping it cool.  it can be fixed again and again using the method above but it is time consuming.  to prevent getting a cold connection which leads to this problem, don't move the laptop.  yes, it sucks that you can't move it but that's the only option you have.
