I have bought the laptop from Acer Aspire 5 (A515-51G-54PF) with intel i5-8 Generation, 2 TB harddisk and NVIDIA MX150 Graphics about A year ago
After 10 months it started to shutdown at random times and will not start until I connect to AC Adapter, after checking with service center It was fixed they told me It was "BIOS Update Issue" and It was fixed but after 3 months It started again.and this time it is more frequent and It is really frustrating... It happens at any time and it runs on AC power adapter well but sometimes (Not Always but often) It shuts down.and IT IS ANNOYING AS I HAVE DONE SOMETHING WHICH TAKES TIME AND IN LAST MOMENTS IT SHUTS DOWN (like video rendering, etc...)
Laptop is not in the warranty now so suggest something before going to service center...
I need to fix this ASAP so Any help is appreciated
