You're welcome @pcfr33k - Not sure why they would disable speedshift, maybe for thermal reasons? You can enable as you see fit now

Hello. Trying to reset CMOS gave me problems - the plastic tab on the MB broke.

I was unable to blindly reset BIOS after several attempts.

There were a few other things that weren't right with the laptop - the fans were super loud and there was significant screen bleed.

After the MB tab broke, and with the other issues (screen and fans), I decided to replace it. OP sent a replacement after seeing pics of the screen bleed (it was pretty bad). We would of replaced it right after buying it and seeing the screen - but they were out of stock so we didn't know what to do. OP Support had stock and was able to send a replacement.

The new one has the latest BIOS, very quiet fans and no screen bleed. The unit is new too, it's not a re-pop or refurbished. All sealed up and smelling like a Chinese clean room.


I'm certain I could of fixed the BIOS with your continued help.

Thanks to all!

@Pear - I have never used or seen one of these systems, so I don't know what this plastic tab is you speak of, but clearing CMOS should not involve any plastic tabs? Glad they replaced the system for you though, without hassle too!

If you need unlocked BIOS now, guide is done and posted here - OverPowered TONGFANG CyberPower Machrevo MACHENIKE - Unlocked BIOS Guide W/ Files

I have Monster t7 v19.3 same (mech 17) bios 1.03/ 9750h/1660ti ''How do I reset BIOS settings after an unsuccessful undervolt? I've tried removing the CMOS, battery and RAM's overnight but didn't work.'' I try fn+d power..... etg I tried everything I could not reset bios

@mnstr - re-flash BIOS again if you can boot to DOS or BIOS. If nothing helps, press and hold down power button overnight while all the other power is removed like you did before.
Maybe shoot email to Monster and ask if they have clear CMOS hotkey-combo. Also, try booting with only one stick memory might reset things too, or other memory if you have.

@Lost_N_BIOS Now I put the phone to the power key will stay all day. I removed the cmos and the battery first. Could the bios be saved on the memory card, so if I leave the PC for 10 days without electricity, it may not be reset?

Phone to power key? I meant, push it down, with something heavy, or short the pins/wire/connector etc. No, I doubt anything BIOS related is on a memory card, but you can go ahead and remove that too if you want.
10 days is not necessary, 12-24 hours is more than plenty, if it's not reset after that then the settings are stored in NVRAM somewhere on the board and only a hotkey combo would reset it. Someone mentioned a key combo or method to clear CMOS in this thread I believe (However, this is not a Monster thread? Are those same systems as these?)

see how much current it is pulling. If it's > 1000 mA (1A) closer to 2-3A, it's a telltale sign it's on. iGFX only keeps it under < 1A easily. I blacklisted the nvidia driver so it never loaded, but it just makes things worse. It simply gave me massive screen tearing on Mint.

Thanks. I ll read more about optimus ! waiting for bios to flash and play around with settings !
installed tlp-stat, I can see it is consuming ~2A.
I have uninstalled nvidia driver and confirmed that nvidia is not loaded (via lsmod | grep nvidia). screen tearing is not happening to me.

PS: Yes, and now I resumed it after 1.5 hours, it resumed :) I am happy!

Update: Thanks again, for more than doubling my battery performance with that acpi_call stuff. A W E S O M E. you have single handedly done, what opowered support could have done :p

@geekasm Great, good to hear! Long story short is basically Optimus and this laptop uses a muxless set up, meaning there is no hardware (discrete) switch to control the graphics. Even if you unload the driver, dGFX will be on. That's just how it works. Simple way to check is to install tlp-stat and run tlp-stat -b to see how much current it is pulling. If it's > 1000 mA (1A) closer to 2-3A, it's a telltale sign it's on. iGFX only keeps it under < 1A easily. I blacklisted the nvidia driver so it never loaded, but it just makes things worse. It simply gave me massive screen tearing on Mint.

The correct way to unload it is to turn it off in the BIOS, or issue an ACPI call like found here to physically turn off the PCIE bus it is sitting on: https://wiki.archlinux.org/index.php/hyb...Using_acpi_call (don't use bbswitch, it's broken on recent kernels).

@vikss - quoting people doesn't alert them you're talking to them, you need to use @ tag directly in front of their name like I've done here with you, then they will get a PM

@vikss - You're welcome Yes, it's possible to use "Some" of the BIOS interchangeably, but you need to pick one that has same GFX as your system so the correct vBIOS/GOP is in there.
And if/when you do that, would flash over the entire BIOS and EC at same time to the stock version, then if you want to apply mod BIOS do that once done with stock flashover.
See notebookreview forum for most and best up to date info on all these models, there a few huge threads in the "other manufacturer" section.

@vikss - The versions listed on the first page of the guide linked below for each model, I believe I have many of those stock if you need, if not I can probably find for you over at notebookreview forums.
I don't use, have, or keep up with any of these models, so I only go by what users request or provide here, there may be newer BIOS out there for many of the models I have listed on first page of guide below, you'll have to google around and see what you can find.

For OP-LP3, I have N1.08 stock BIOS linked on first page of the guide above, but that does not contain the updated EC File to go along with it. I think @blind012 emailed them a while back for matching EC FW, but unsure if he ever received a copy or not
@pcfr33k may also be able to get us a copy of that EC that goes with BIOS N1.08, I think he can dump it if he has time.

Read online at Techwala site that there’s another way to unlock menu options. I quote:

“Press the "Alt" and "F1" keys to unlock the hidden settings on the AMI BIOS. If nothing happens, try pressing "Shift" and "F1" or "Ctrl" and "F1" instead”

Anyone try?
