2.) +batt con with ac adapter plugged in is same as without ac adapter. (it is battery voltage, I did try with serveral batteries, and did try all of that batteries in other Acer and they all work normally)
3.) yea on coil L8800 I got 3V with battery disconnected and charger plugged in.
4.) bat_sys with just battery 15.08V and with charger connected is jumping from 15.08V to 19.67V every second
Hey guys,
I got problem with Acer SF314-52. Problem is that laptop wont charge battery, I did put new battery which was on about 60%, and laptop was plugged all the time and battery went to 1%. Laptop is normally working on charger.
I did try to replace first two mosfets --> same problem
I did try to replace BQ chip --> same problem
I measure that on coil next to the battery connector (which is connected with + of connector) I got about 3,5V.
Device: Laptop
Brand: Lenovo
Model: V330-15IKB
Board number: LV315KB ; 17807-3M ; 448.0DC05.003M
Request: BIOS
I did found some BIOS here, but I think it is for 7th gen Intel CPU and I need for 8th gen CPU because with that BIOS what I found my NVME disk wasn't detected. Did also found some BIOS for V130 but then I need to wait for about minute to POST.
