Hello!
Is it correct machine model number? If I'm not mistaken there should be different board in this model (LA-F114P, LA-F115P or LA-F116P).

Hi matic, my bad, model is Inspiron 3781.

Try this one: www.elvikom.pl/dell-inspiron-3581-mb-compal-la-g714p-rev-1-0-t65556.html

I tried - no screen. After switch on current is 0.35-055A, after few seconds 0.35A. No +VCC_GT and +VCC_SA. I copy me region from original backup dump, but someone soldered bios chip before, so I'm not sure this dump.

I havo low resistance on VCCSENSE, VSSSENSE, VSA_SEN- and VSA_SEN+. It's may be cpu fault...

Check, if the "Service Tag" on the machine label matches to the one in old BIOS (if i'm not mistaken, it is located at address "813327" of BIOS).
If it does not match, the BIOS chip was previously reflashed for sure. In such a case you need to reflash the BIOS with a cleaned ME-region.

Matic, do you have dump with clean me-region?

No, I don't, but I can try to clean it, if you need.

Have you tried with my BIOS dump without transferring the ME-region? If so, are there any changes in power consumption of the board in this case?
