    Yeah, I saw that. But I'm using Windows 8.1 still. However, I did try CSM. It still did not work. Safe Mode is black screen with a cursor that disappears unless I move it around. Trying to bring up task manager with Ctrl+Shift+Esc does not work. Sticky Keys by pressing Shift 5 times also doesn't work. Nothing from the keyboard works. Yet I can see the mouse if I move it, so it is not a display issue...

    I did a lot of digging yesterday, but all results come up as problems with the normal windows boot, not Safe Mode. I saw a suggestion saying that it might be a virus but MalwareBytes and Spybot don't find anything.

    I also checked the registry key that most people suggest might be deleted by a virus causing this, and it is still there so that's not the problem either.

    I installed a new nvidia driver by just uninstalling the old one in normal mode without using DDU. And the problem still persists in Safe Mode.

    Ran chkdsk and sfc scan and still nothing.

    This is very puzzling...

    Wow, 2 years in and this laptop continues to annoy me. AC adaptor is not charging up this up for me anymore. Should any np9752 adaptor from any reseller work with my laptop since I don't want to deal with my reseller again?

    edit: nope, I'm dumb. Was the loose plug that connected directly to the adaptor end. Forgot that plugged in at that end as well as the outlet end.

    D'oh!

    Mine's going on 2 years and it's been fine other than the dead display panel which was either Microsoft's or nVidia's fault, or both, but not Clevo's.

    When it comes time to replace it in another year or two I think I'm going to avoid the whole gaming notebook thing, though. My Surface Pro 4 has been able to reasonably run almost everything I've tried on it. It's remarkably capable for a mere 35W processor (CPU and GPU combined) in a sub-2 pound package.

    I have a P7500ZM model from PC Specialist and have managed to botch the BIOS with a failed premamod update (serves me right for not taking care over the instructions).

    Is there a means of recovering the BIOS on this model? I have tried removing power, battery and CMOS battery without success, and also tried boothing with Fn+B pressed. Ditto attempting to boot with a stock P7500ZM BIOS on a FAT USB stick, although I couldn't be sure what filename the stock BIOS should have (tried P7500ZM.ROM, AMIBIOS.ROM, AMIBOOT.ROM and SUPER.ROM). In each case the power light comes on and - sometimes - the fans start up, but that's as far as it goes. There never seems to be any access to the USB stick (no USB LEDs flicker).

    Is there a BIOS jumper on this model that can reset the BIOS? I did look at the service manual but couldn't obviously see one.

    Any suggestions appreciated.

    At first: Don' t go back to stock BIOS. There have been problems reported which you don't want to hassle with additionally.

    You can ask in this thread: http://forum.notebookreview.com/threads/clevo-bios-thread.416916/page-411#post-10433032

    This guy even described a repair method. But it seems (the autuexec-text for example) that it is a bit BIOS and laptop model specific, so check out the details first.
    However, use the same BIOS you bricked your laptop with. Or if you took the wrong Prema-BIOS (You didn't give details) use the up-to-date Prema-Version.

    PS: The model name is P750ZM or P751ZM.

    Many thanks, I will ask in the thread suggested. I have spent time trying to restore the same version of BIOS I began with, albeit with no success at all. Power comes on but I can't see any USB access nor do the fans seem to kick in (at least, not obviously loudly).

    Re: your question I'm not sure I used the wrong Prema BIOS, however the laptop did simply power off part way through. I will try again using the current Prema BIOS, however I'm not sure the laptop even recognises the USB key (I tried a couple of USB sticks just in case one wasn't recognised).

    Anyway, thanks for your suggestions, I will post over on the other thread in case of any other suggestions.

    Hi everyone, long time no see ;)

    I wanted to flash prema bios mode on one P751ZM but I've noticed something odd - the file size in T|I forum is twice the size of the one on Prema's site.. It was also "updated" after it was posted on his site.. I was wondering if someone who have/can download both files could compare it, and if possible provide the one from T|I? I've registered myself there, but can't download anything yet.

    I suggest reading up on the thread over there and asking about it before jumping in feet first into a third party BIOS mod ;)

    Which file are you talking about? The one in the very first post in this thread by @Jaybee, which includes the 970M and 980M Bios-Mods?

    The one hosted on T|I forum is twice he size as the one from premas site - possibly different compression type, thus the question if someone who have access could compare.
