Acer Aspire E5-574-52RH - black screen
Hi everyone,
I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
Laptop came in for a SSD upgrade, took everything apart to install the SSD.
Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image
Symptoms are:
- random black screen after displaying Acer logo...

Re: Acer F5-572G - black screen when changing boot to Legacy
So i followed your advice. I programmed Peste's bios on the good/new chip, put the chip on the board and power on. Got image and went to bios to se password and then saved and exit. I entered bios one more time to change from uefi to legacy boot, save and exit and after that black screen only. The same as before. If i recover bios from Fn+ESC with official bios 1.18 (file ZRW.fd on usb) i'm back to image on screen and default settings in bios.
I'm thinking this is another problem and not the bios.
Thank you...

Re: Acer F5-572G - black screen when changing boot to Legacy
I bought a new Winbond 25Q64 and i use it for testing bioses. Old bios chip has some problems when i try to write or erase.
I am using an Orange5 Universal EEPROM & MCU Programmer and latest software 1.36. I did comparison after writing, all ok.
I dont understand the bios pass stuff? If i set a pass will i be able to do what?
Thank you guys for your support!...

Re: Acer F5-572G - black screen when changing boot to Legacy
All the bioses that i tried were written on a new chip. Original chip gives me some error when i try to program/erase.

Re: Acer F5-572G - black screen when changing boot to Legacy
I just flashed your bios, it powers on with image. I entered bios to change from UEFI boot to Legacy and after saving and exiting bios the laptop show no image again. I am pretty sure that after i reflash your bios again it will power on fine, this is until i change to Legacy boot.
Any ideas?
Thanks...

What i've done so far:
- check for shorts, measure power rails, all ok

But... it defaults to UEFI boot and as soon as i switch to Lecacy boot black screen again. I did USB recovery again(it works everytime) and i tried to...
