So three times this week my laptop has shutdown after about 4 hours of gaming (it was plugged in), both with the CPU at normal voltage and undervolting, no warning messages or notifications about low battery. Since this happened twice already this week, today after 1.5 - 2 hours of playing, I checked battery status and it was above 75%, but then about 2+ hours later low power shutdown, so it seems like maybe there is a critical drain happening. Acer care center app says battery attention needed, a scan says that "battery life is degraded due to normal usage". As far as I know the battery is only supposed to drain to 30% then stop, which it did since day one of owning it, but it is not doing this now. The laptop is about a year and a half old so no warranty, but honestly if this is normal I am shocked.
My concern is that this makes my laptop mostly useless as a gaming laptop, and none of the 5 other gaming laptops I have owned in the last 15 years has done this when the battery was degraded. No changes to my system or anything else in the last few weeks. Anyone else had this problem? Ideas/ suggestions? Acer any defects in the batteries is laptops sold in Asia in 2016?
