Am I reading it right, you can't get into BIOS?

 

Thanks for the reply. Unfortunately, the CMOS battery is soldered in between the connectors, however I did manage to pry off the negative terminal and then set it back on the battery. It did not help. I will try the suggested steps by you and report back. Thanks again.

Try to do all steps, but skip disconnect the CMOS battery.

No luck so far.

 

Just to be sure, this is the CMOS battery right?

Should this Intel Dual Band Wireless-AC 7260 work on my Lenovo Y500? Like could i just take out the old Qualcomm Atheros AR5B225, put this Intel one in, connect the 2 wires that i'm assuming are antennas, boot wWindows, install the drivers from Intels website and be good to go? Or am I gonna have to do some of this annoying BIOS modding stuff?
Edit:
BIOS Version: 6BCN42WW(V2. 02)
EC Version: 6BEC42WW(V2. 02)
I'm using Windows 10 in case that matters

And while we're at it, how can i use the ultrabay for a 2,5" SSD? I currently have the one with a second graphics card. Would I have to buy a whole new ultrabay that was meant to be used with a 2,5" drive? I'd rather buy a 2,5" SSD than an mSATA SSD, but if it means having to get a new ultrabay then i'm just gonna go with the mSATA SSD instead.

Hi!

This means that you need execute prr.exe before you flash mod bios. All steps already described in first post of this thread.

Just to make sure: unlocking the BIOS wouldn't do anything bad to my system? I do not need GPU overclocking features, will they be disabled by default?

Nothing can go irreversibly wrong during/after BIOS install if I'll be able to successfully make a BIOS backup like instructed? 

 

I just want to install 5ghz and ac-compatible wi-fi card and thinking of ordering 7260ac.

As long as you follow the directions, You should be fine. Nothing is overclocked by default,you just have to option to overclock if you wanted to.

I have successfully flashed my bios with the modded one. Do I need to flash my second GPU now? This is how it looks like in nvidia inspector. My main GPU says modified and not the other one. (See pic)599a031265111_Namnls.thumb.png.b734081d773efef31f2ccda59d720489.png

Second GPU needs to be flashed separately.

Thanks for the answer. Im a lil bit confused. I have never had a SLI laptop before. What's your settings in NVIDIA control panel? Do you have it set to auto or cpu? Or does it matter?

The vBIOS for the second GPU needs to be flashed separately. As you saw, only your primary GPU vBIOS says modified, so now you need to do the second GPU.

I have SLI enabled and PhysX set to auto-select (GPU2), which are the defaults:

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.

      Hey guys, I have an Alienware m14x R2, and I have been trying to get access to the BIOS so that I can change the boot options (Everything is locked, I am unsure if someone set a password of if these are locked by default).I've tried updating the BIOS, and resetting the CMOS and nothing has changed this. Would anyone know if there are other options I can explore? Thank you.

      In this thread you can post your requests for Lenovo ThinkPad X250, X260.
