Solution:
This is awkward but I have been testing my laptop whole time without bottom cover screwed back in.
And this was the problem, probably some connections needed pressure from screws and now everything is fine.
Hello guys,
I have performed HDD swap for new SSD on my Acer Aspire ES1-311 laptop. During disassembly I disconnected the battery by pushing button (showed in pictures) directly on my mobo and then unplugged the cables from the motherboard.
Then I proceeded to switch the drive, repaste the CPU cooler, clean the dust etc…
After plugging back to DC and installing fresh Windows and drivers directly from Acer's site everything works just fine, except for the battery.
It is detected by the Windows, I can get readings from HWMonitor (13V, cca 18% battery wear) and even build in battery status LED is on. But when I unplug the charger, laptop instantly switches off.
At that point I tried switching back to the old HDD but the same thing is happening and as a bonus I can't get to recovery partition because "laptop couldn't load it, try contacting your administrator". It probably got messed up during partition cloning or year ago when I made another partition for my dual boot.
I am probably accepting the fact that the battery has died, but it seems so weird because it was disconnected for the whole time and I didn't bend it/heat it/smashed screwdriver into it and the timing, that some of the cells died just now is very unlikely.
Before that event battery had no problem with 5 hours of work.
I would be really grateful for any suggestion or advice, as I still hope, that this is software/firmware issue.
Methods I tried:
Remove battery -> turn on -> turn off -> reconnect battery
Check wear level and powercfg - this looks fine
Messing with power management settings
Installing all drivers
And probably some more, that I cannot find links to right now.
Thank you for any advice
