L512 Wont Boot , Splash Screen then stuck blank screen and Fan in full throttle

2013-10-24, 23:03 PM

I was using the laptop, then it went to suspend mode due normal timeout.

When it came back, the fan start to spin full throttle but it was functionating  beside that, normally.

 

I restarted but then it never boot again.

This is the process where it gets stucked

Boot to Splash Screen, Beep, then a black screen and the fan start to spin at full speed.

(In the post in diagnostic mode, shows no error, pass the memory check, shows the info of the processor )

 

 

I tried this:

 

Retired Hard Disk,

Press 60 Seconds  (Reset BIOS) - without battery and power cord 

Press 10 times the power button an then 30 seconds -- without battery and power cord 

 

Visually there is no damage in the usb ports, maybe i  will need  to disassembly to get a better view to check if there is a short somewhere.

 

 

With this symptoms , what should else i try.  Could be a memory issue?

 

Thanks for any help you can provide me.

I have tested  with another Dimm, with the same result. So that  let me discard  a module issue.

 

Here is a bios summary : 

 

 

An here is how it boots right now:

Thanks to the Mod! :)

It happens that if i wait for about 30 secs, then it will boot up, asking a proper boot media.

I was testing it  and was workiing fine, except  for  the Fan working at full speed, Not suspending or shuting down or Hibernate. Only blinking power button led. So a rude disconnection /Battery Extraction needed to acomplish full shutdown.

 

But Now in the bios diagnostics splash shows

2201: Machine UUID is invalid

 

 

The bios shows only 0s in the uuid section.

i was looking for some imformation about this problem, and i found tah can be solved using some kind of floppy for servicing the laptop.

 I ve already downloaded a copy, Havent tried yet, But plan to do some test. as soon i can get some spare time.

It appear tha some comand will let me regenerate  the UUID, and with some luck, reflashing the bios will solve my problem.

 

I'll update as any new steps performed ;)
