From experience, always confirm bios is OK via uefi tool after backup, it is very important else you'll end up with bootloop when you reprogram it.
You'll get invalid checksum or any error messages at the bottom of the uefi tool.
Again, using another chip instead of the one that came with the surface pro won't allow it to touch or boot fast....

Have you check the vcc resistor to charging ic?
Also the ACN/ACP SRN/SRP communication with respective CLR to see if it communicate?...Leave a comment:

Does it turn off with power button, when you press it down?Leave a comment:

Re: hp elitebook 840 g2 power button voltage drop 1.8v
Search for D100 there are some resistors close to the empty diode space, one of the resistor will read 3.3v at on side and the 1.8v at the other pin, same voltage on your power button, replace the the resistor with a 1k ohms resistor and you're good to go.
This will help to safe the sioLeave a comment:

Re: Acer e1-431 dead no power led, no PWROK_EC
Check the impedance of Rsmrst #, I kinda think this is a pch fault issue. The DNBSWON# 0v gives a glue.Leave a comment:

Re: P3V3A has low resistance
You remove the possible pch problem or you removed the pch chip from the board?Leave a comment:

Re: toshiba c850 hdd not detected issue
First of all reprogram the bios, you can also check the TX and RXN line capacitors for shorts.Leave a comment:

Re: Lenovo E540 no 3/5valw
Since entrip is available, replace the polarized capacitors but your Pin 13 is 1.3v which is wrong.Leave a comment:

Re: Dell Inspiron 5520 LA-8241P Not working with battery(For freshers only)
Which means it doesn't display when on battery is connected.
Like you said ,the clue in on the core section, then it could be that the required current is not really generated with the battery.
Changing the Polaris Caps could be a possible fix or one the upper drain MOSFET is faulty.
I don't think it's a NTC/PTC issue.Leave a comment:

Re: Dell latitude 7420 need clean me
I used a pogo adapter to back up,I guess that's where the problem came from, when I decided to write another file on it I kept getting the write error via pogo adapter,I then had to remove the chip from the board and use the adapter board.
Now I already write another file and there's no way I can get the original back up file again since the first one I used pogo adapter with is bad.
Is there a way you can help me build a new file without the backup because as it stand, there's no way I can get a...Leave a comment:

Re: Dell latitude 7420 need clean me
The file size is 32mb but I get the 61kb any time I compress it.
Is there a way you can help me build without the backup file? Looks like the main file is corrupt and I already flash a backup file from here,the SSD is not showing....Leave a comment:
