Hi tomshardware members. I made sure i tried ALL possible fixes before i default to asking others for help,but i've had no luck
So i have a pretty puzzling issue that's been skin-peelingly fustrating to fix. I have an Acer Aspire 5552g laptop with a newly installed motherboard and ram that works perfectly fine with the AC adapter. However, once i unplug the AC adapter, the laptop shuts off with 10-20 minutes of usage. And it's not a normal shut-down. It freezes for a good 2-3 seconds, the fan kicks in, and does a hard shut off. No warning or anything. I made sure the connections where correct when installing the new mobo, per manual instructions (and some visual help on youtube) and it definitely does not overheat. I check temps constantly for any anomalies.
But it still shuts off when it is not using direct power supply from the AC adapter.
I figured the original battery was defective, so i purchased a new battery from acer that came in a few days ago and it's still happening on this new battery.
I flashed the bios with a current version from acer support site. I tried taking the battery out and holding the power button for 20 seconds to discharge whatever any currents that may be stuck i guess (read it somewhere on a forum). BTW the OS is windows 8 pro (clean install and updated drivers). I also have windows 7 home premium installed (dual boot/ with updated drivers as well) to see if the problem persists there as well, and it does. I figured maybe these windows OS's have problems so i tried booting a disk image of Ubuntu and it also does the same problem here too.
Im at a loss with why this is happening. The Laptop works fine when plugged in, but every time i unplug it (no matter what OS; win8, win7, Ubuntu), it still shuts off without warning after a few minutes.
I should mention that this issue doesnt occur when im in the bios or windows8 safe mode. I left in the bios over night to kill the new battery so i can calibrate it but that hasnt worked. I charged it up fully again and put It in safe mode right now. I unplugged it and ive been letting run without the power cord. Its been fine for almost 2 hours. So im clueless what the issue is.
It doesnt seem like a battery issue. It must be something in the normal boot of the OS's thats causing it to shut down since in bios/safe mode it works fine without the plug.
Any ideas? Sorry that i threw out a ten page essay. This issue is just irritating for the past weeks and needed to inform in detail everything ive tried. I dont wanna have to rely on power cords for this laptop since im a student
Any help is greatly greatly appreciated.
