Hello great Community and Hello Alex,

im from germany and watching your videos since beggining. Keep up the good work.

Time has come that my laptop wont take a charge, strange thing is that it is stuck at 15% then 255% and says plugged in not charging. I have tried many thing like, unplug battery hold power button 1 min, sometime helps its alive again but most of the time ist stuck at that percentage. 

Tried with new battery but same thing.

One thing that stud out is i read somewhere that the new bios 308v is the problem, so i downgrade it to 307v and it worked for some time but last night it hapend again with that older v of bios.

my question:

could it be  that my bq (BQ735) chip is bad? cuz laptop has no shorts everything looks good, no visual damage no discolored comp.

Hope someone could guide me to right direction. TY
