laptop keeps on crashing when not charging(Acer One 14 Z8-415)

It has almost been a year since the purchase of my laptop and since the beginning, even when i was setting up my laptop when i wanted to boot it up or put it under a moderate load such as opening a browser, it kept on crashing if it was not charging, i have tried reinstalling windows but still no luck, the way i found to resolve this is issue is to disable all start-up apps, to minimize the start up load, however since my warranty is about to expire, i wanted to know if there is something i could do, or should i contact acer support
