I upgraded my old laptop with i7-3632qm and its working fine, temps are ok but he wont boost. Lenovo g500s could be bought with i7-3632qm and it had same cooling as was 2020m so i dont think cooling is problem. Can i bios unlock? I cant acces advanced settings in bios. i need help
If someone wants upgrade Wi-Fi card and remove witelist, or unlock hidden additional menus and settings, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread.
Hello, I have several Lenovo L530 notebooks, but there is no wi-fi adapter inside. I tried to use my wi-fi adapters, but whti every adapter I have an error "1802 unauthorized network card is plugged in". I have already used all available wi-fi adapters, but no result. I really need professional help and I hope I find it here. As far as I understand there is a way to remove whitelist in BIOS, so here's the file with my BIOS dump.
Hope you can help me with BIOS mod. Thanks in advance.
P.S. Sorry my English, I'm from Russia
Hi all! I am wondering if it's possible to remove the bios whitelist easily. Because of the whitelist, my external gpu setup that I got recently refuses to work. If it helps at all, I know that the wifi card that used to be in the slot was the intel 8265ngw. Here's the bios link if that helps too: laptops and netbooks :: thinkpad x series laptops :: thinkpad x380 yoga :: 20lj :: 20ljs20n00 :: mp1e15eb - Lenovo Support US
Thanks for your help!

We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
Here's some common problems and some troubleshooting steps to correct them.
Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
Use the Setup1.30 PCIe Ports->enable to enable the missing port.
eGPU does not get detected
Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
eGPU still not detected - set the PSU to be permanently on
The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
eGPU still not detected - a non-standard mPCIe implementation by your vendor?
PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
eGPU still not detected - faulty hardware?
If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
NVidia driver stops responding
EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30
