[titomno2]

Good Evening,
I'm facing an issue on lenovo M600 tiny with celeron N3050, bip at start with Error 0199.
I tried to dump the bios (verifying 3 times the checksum, same numbers). But when passing in auto pacth I have a stange message:
Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
m600_lenovo.bin is corrupted or does not contain a valid dump.
There was an error... Aborting.
But since then computer is not booting anymore.
Tried to inject the save bin but stil the same issue (start when plugged in) but not picture and no light on the front panel !

Could someone have a look and help me to undersand what is wrong.

Thank you for your kind help.

Have you got the CLR_CMOS jumper on the right pins. Try this bios.

Hi guys,
Sorry for late answer I have to hit the road today.
For Azad192, No I did not found the problem and to be honest my last try I thin I have burn both of the controllers U12 and U37 (both where flashing on thermal infrared camera indicating that there is a short somewhere and not on the power line).
I must see to buy some of these, not sure how many time it will take.
I have a working board on which I dump the BIOS but just after I have falshed it inside the bad board I fried the controllers so I prefer not to share it as I does not want to burn your motherboard if anything is wrong.

For SMDFlea,
Thank you for your help, I will try it as soon as I have fixed the short (if I can identify where it is).

Thank for your help.

I have mixed feelings on lenovo product, some are great I have M93p and M700 working just fine. And some other are strange, one locked itself with bios password (I never setup) and cannot remove it with standard tools...

More Information next week.

Hi guys,

Small update, the cpu is fried.
After carefully replaced both controller, the cpu is heating on one spot... it is fried explaining why I suddendly don't have any respond from the motherboard.
Subject is closed for me.

Thank to all your support.
