[help] lenovo thinkpad 14 g6 SEMI-DEAD

[phantomEVO]

i don't know the history of this notebook.

if i try to power it up, i have only the charging led blinking slowly 3 times.

if i connect the power supply with the amp meter, i can see that it switch to 19v and suddenly the display of the amp meter goes off

if i connect the power supply with the amp meter WITHOUT the battery, it remains on 5v but the display of the amp meter doesnt go off

why do you ask me about this?

[phantomEVO]

i don't know why, but know it's charging perfectly with red light !!!

strange thing is that it's seems it can boot: i press the power button, keyboard lights up with caps led on, .fan spin .but nothing happen. black screen and mothebroard / cpu is super hot

cpu is super hot

The battery charging is handled by the EC (stand alone microcontroller) that is the bus master for the charger IC. The CPU may be dead. Test the resistance to ground of the CPU vcore rails. No power to the board during the resistance checking.

i've seen that the most hot thing is the ram (ultra hot wirth its label that it is like melted!) another strange thing is that, while charging, i can ear like a "click"

i've ordered another ram...just to test...
