Model:Lenovo Ideapad 110-15ACL
MB Code: NM-A841
Problem: The laptop came with charging issue. PQ303 Was shorted and PQ308 was corroded. Both item replaced with exact same parts. Now , its charging, works fine from adapter only but doesnt gets on from battery only(Battery is perfect and tested on another lenovo laptop). However, if you connect the adapter once and remove it and then instantly if i try to turn it on-it works from battery only. After a gap of 2-3 mins, it wont work from battery again.
I've flashed virgin bios from lenovo site but issue persists.
PQ303-PIN 5-6-7-8 reads 11.6V on battery only
PIN 1-2-3-11.6V on battery only, PIN4-no voltage.
In adapter mode: Pin5-6-7-8 reads 11.6V
Pin 1-2-3 reads 19V, pin4 reads 18.2V
PQ308 is working correctly(schematic is wrong in this part). Pin2-3.3V,pin3-19V, rest pins 0V in ac mode, On battery only-all pins 0V.
PR304/305/306/347-rating ok as per schematic. PD301/302 also ok.
Battery pin volatge:
PIN 1-2-11.6V
PIN 3& 4-3.3V
PIN 5-0.3V(only when adapter connected, else 0V)
PIN 5 voltage- PR203(100K) & PR204(10K) acts as voltage divider. I do get 3.3V on one side of PR203 . So to me pin 5 voltage at 0.3V seems ok.
What could be wrong here??
I've replaced charging IC OZ8682 also(NEW)-same problem persist.
PS: I tried but couldnt flash ITE8586 as svod2 gives error-cant detect ite series.
