Hi,
My laptop (4yrs old) was giving me "No battery charging" indication for few months and worked only with AC adapter plugged in. In the last few days it was required to remove and re-insert the battery to Turn on the laptop. Now it is completely dead. already checked followings.
AC adapter-ok
DC in jack-ok
no sign of overheating (melting)-ok
Checked with another 65W Battery-not successful

Please help me to resolve this.

first, take the mainboard and plug adapter, please measure PL10 & PL11.

PL10 for 3.3V and PL 11 for which voltage?.
Did you refereed to following circuit?
Could you please elaborate the steps as I'm an apprentice.
