Hello I was wondering if it's possible to downgrade BIOS. I have Acer TravelMate P633-M with BIOS version 2.15 (latest). I had 1.12 and by the time I was upgrading it but unsuccessfuly and my laptop won't turn on. Then some PC service fix it but my laptop don't POST correctly. When I press power button the light comes up and that's all. No optput on monitor. But when I power it down (by button) and immediately power it on, it boots normally.

    It's most likely not the BIOS. Can you get into the BIOS Menu at all? Does it show the splash screen when you turn it on?

    OK, so we know the hardware is working and it's likely failing during the initial Windows load, not during POST. Do you ever see the juggling balls after the splash screen? Can you attempt to boot into safe mode?

    No the Windows load without problems. As I sad. When I press the power button the power led light and nothing happening. I don’t have the output. Splash screen don’t appear and I also can’t access the bios. Nothing works. But when I power it down by button and immediately power it on, the splash screen appear and it booting to windows.

    Could be, try booting into safe mode. That will bypass the GPU drivers and use the generic stuff instead.

    But my laptop boots up every time when I power it on again and then works perfectly. I think that something happening during POST. As I sad. When I power it on for first time. Nothing happens but when I power it down and power it on then I have the output at screen and I can see windows 10 boot screen. That’s the problem. When I want to power on my laptop I have to power it on, off and again on and then my laptop get POST. Everything then works fine.
