I have an Surface Pro 4 , i bought the device with the battery allready swollen , so the display was a little bit peeleed off , but was working normal and perfect.
I succeded to unstick the display , tried after that to power the unit , worked perfect.
Replaced the battery with an second hand one , that from what i head from the pervious owner , the battery stayed for 1 year or more , so probably is empty.
After i reattach the battery , no sign of life from the unit. I tried with battery removed same no sign. After that i had read that need to isolate the battery pins from the mainboard , tried even like that , nothing.
I had checkd , the diodes , all are fine , the 0ohm resistor is ok , even i have 3.3V on the IC.
What else to check ? Could be the battery problem ? The ideea is , i don't want to spend other money on a new battery to see that will be the same , without life ;)
