BASIC CHECKS:

TPS51225 3.3V and 5V
Pinsvreg3 vreg5
Check those pins for output. without those voltages on those pins the notebook will not power or charge the battery.

General keywords and problems related are NO POWER.
PinsEN_3V EN_5V equally important to vreg3 and vreg5. KEYWORDS – LDO Low-dropout Regulator

If there is 3.3v and 5v from TPS51225 and there is no EN voltage then replace TPS51225 and reflash BIOS.

PU301 – RT8205LZQW

Near PU301 you will find 3VALWP and 5VALWP.

Those voltages are always on even before power button its depres.

To check them you need to probe on PL303 for 3VALWP and PL305 for 5VALWP.
If you got a short with ground reference the lift the coil in question and see where the short is located. inject 1-2v with max 1amp to located the faulty component.

Maybe problems where found on the B+ or B++ with mosfets that where connected to ground or SMD caps.

U49 MX25L1606EM2I

Check the main BIOS if there activity on pin 1,2,3 and 7.

On oscilloscope it will show even if power button its not press, only with adapter connected.

If those pins got flat line on oscilloscope showing constant +/-3.3V without any activity, reflash the bios using an external BIOS programmer.

After flashing the BIOS with the right image activity must be on those pins with only adapter connected.

Sometimes the BIOS IC may be broken and it will show only when Verify its operation its done on the chip. Replace the chip with same model.
