回答“Acer nitro 5 doesn't turn on”mine has exhibited symptom of power button press produces no result a few times in past week. Jus did this again today worse than others.. Tried all the tricks.. Tried long press. tried short press. Tried many fast short press. Tried plugging charger in and the light was blue but allowed it to charge for 5 min. No luck. Continued to tap periodically then suddenly a little beep after maybe 5 minutes of this and it powered up. Windows power meter shows 100% charge so it is not a battery issue. Is maybe a switch that is actuated by pressing the key. Can’t say but very disappointed that an $800 laptop seems to be failing and has become unreliable in less than 3 years. Actually I think less than 2. Acer owners need to get together and complain befor Acer gets away with this again.
