When plugging the power cable, I get 6 red blinks and 3 white blinks and nothing happens

[josemariogomes]

Imediatly after plugging the power cable, I get six red long blinks and three short white blinks. The computer doesn't power on, neither the fans or anyother components give any signs of powering on.

I've tried to unplug the power cord and then plug it back on but the same thing yields.

Hi

The closest match I have is...

Main- (Mother) Board

5.3

The embedded controller times out waiting for the BIOS. Component is not reachable by BIOS in certain time limit.

1 Reseat component. 2 Test known good component. 3 Replace component or Main-Board as needed.

So an F2 Diagnostic if possible.

First:- Turn off the computer, press and hold the PWR button for 4 seconds.
Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

If in doubt please ask.

Hi,

Thank you for the prompt response.

The problem is that after plugging the power cord, the blinks start and nothing else happens. The PC does not give any signs of life, so nothing in the screen appears.

Hi

If the ESC key does not respond, then it would seem to be failing to POST

Power On Self Test

and that means you should perhaps pay a local repairer to fixit.

I would remove all internal components, like the memory, graphics card, CPU etc, until it is a Bare Main Board, then power on and see if the Blinks have changed.

Then Power OFF add CPU and HeatSink Power ON, and repeat hoping for an indication of which hardware component causes a change.  OR check as you remove items.

Also ...

Hopefully one of these documents will cover (and solve) your problem...

I guess the best thing to do is to go to a repair shop. Nevertheless I will review the documents you've sent and, if I can, try the solutions you've mentioned.

Thank you for the response.
