I have an Acer Aspire E5-571P-5930 that I purchased in 2015. I recently bought a new LCD screen and battery for this model since the LCD screen was having hardware issues and the battery had never been replaced.
Just before these new parts came, my laptop suddenly shut off and would not boot up. Whenever I pressed the power button, the computer would attempt to boot (I.e. blue light would come on) but then after a split second immediately shut off. I tried booting up with the new battery, no battery and the AC charger, and the old battery, but the result was the same. I then tried the trick where you remove power and “drain” the power by holding down the power button for 60 seconds, but upon reinserting power my laptop still failed to boot after a split second.
I figured I’d try some hardware troublshooting while replacing the LCD screen, so with the laptop opened up, I:
1) Re-seated and cleaned the RAM sticks
2) Unsoldered the CMOS battery, let the motherboard drain for 15-20 minutes, then re-soldered the battery
3) Reseated all cables
4) Replaced the LCD screen
I then turned on the computer with both the battery and AC charger and the screen worked and it booted up! It did mention it needed to do some repairing, which I elected for. I then logged into the computer and left it running for about 10 minutes. After this, I then shut down the machine to officially close up the computer.
But sure enough, after I closed everything up, the computer couldn’t boot up again! I then tried all the different power options for boot-up, but nothing. I then thought maybe the BIOS was corrupted, so I attempted to initiate the built in BIOS recovery, but it appeared my attempts didn’t do anything (but maybe they did?!?!). After more fruitless attempts, the computer finally booted up, but now the LCD wouldn’t turn on! I verified the computer worked through an external monitor. I then re-opened up the computer, re-seated the LCD cabling, turned on the machine with only the AC adapter and no encasement screws in, and the LCD screen worked!, but ONLY if I had the external monitor plugged in. Yes, plugging in the external monitor made the laptop screen turn ON, and OFF when I unplugged the monitor.
So convinced the blank screen wasn’t a cabling issue, I re-closed the laptop and booted up the computer, but the LCD screen was totally off. I then tried some more power cycles, and sure enough. the computer won’t boot up anymore. I’m letting the laptop rest without a battery inserted for the night to see if that helps.
I know this is a TON of detail, but any ideas or insight from where I’m at now would be greatly appreciated. Here are some guiding questions:
1) What would have caused my computer to shut off and not be able to boot-up in the first place? I understand my troubleshooting may have further messed things up, but I’m trying to pin point the original cause.
2) Is it possible I somehow corrupted my machine during all the power cycles? That would seem to explain the unpredictable behavior I’ve seen so far. If there’s corruption, then what’s corrupted? The BIOS? The OS? Both? What reset options do I have that don’t involve an entire factory reset?
3) What would be causing all the weird behavior with the LCD screen not showing up? I tried several different “quick and easy” tests (power-cycling, hot-keys, etc) but no luck. Again; I think the LCD hardware is working.
4) What next steps would you recommend I try?
Thanks for making it this far. I greatly appreciate it!
