So, few weeks ago, I bought a new Aspire 5 (A515-51G-59Z0).

The annoying problem is, I can't run the laptop on battery power alone, as it will shutdown randomly.

Not only on heavy task, sometimes I just use it for typing or watching movies, then it will suddenly died.

When I reboot the laptop later on, it seems like the system is having "soft reset", all the settings applied before the sudden shutdown will be reverted to its original state.
(example : muted volume will be full volume)

Sent it to Acer service center, they claimed to have updated the BIOS, but the problem persists just after my first boot when I brought the laptop home.

The problem will only occur when the laptop runs on battery, not on AC power.


So, any halp?

Maybe too hot. Try put fan and see

ask refund from ur seller
