Hello Guys, If anyone is having BIOS config issues like if you changed an option then saved and the laptop won't start, i'll give you some steps to follow to reset the BIOS on a Lenovo Y50-70. ***FYI: I haven't tried this on any other Lenovo laptop so feel free to try it.*** WARNING: *****For this steps i recommend a 2nd person to tell you when the laptop power cycles on and off for a few seconds on a couple of the steps below.***** -Step 1: Open up the laptop and unplug the AC Charger, CMOS Battery, Laptop Battery and RAM Modules. -Step 2: With everything UNPLUGGED, press and HOLD the Power button for 30 seconds. -Step 3: Connect the AC Charger to the laptop and turn it on, at this point the laptop should turn on and turn off every 3~5 seconds, leave it like that so you can know the interval of time that you have. -Step 4: While it's OFF, quickly connect the CMOS Battery, wait for it to turn on and off again. -Step 5: While it's OFF again, quickly connect 1 RAM Module, wait for it to turn on and it should give you the "Lenovo" BIOS logo at this point. *You can wait until it reaches Windows to turn it off or just press the power button. -Step 5: IF you're good, you can proceed to leave it OFF and connect the other RAM Module and the Laptop Battery. -Step 6: Close your laptop undertray and power on and make sure to setup your BIOS once again because this will load bios defaults.

I was looking to open up my y50-70 and replace the thermal compound with liquid metal, but I can't find any information on the heat sink. I know you can't use LM on an aluminum heatsink, so how do I find this info? Didn't see it in the user manual- does anybody know if it is safe to use liquid metal on this heatsink?

Hi . İ need your hepls. Firstly my notebook model is lenovo z500. Intel Core i7 3632QM gt645m g. i could not find information abouth z500. Does eGPU work on Lenovo z500 ?

Hey sorry for my bad english and sorry if this question is kinda stupid.. So i have a y500 650m SLI and already flashed the bios. I thought about getting myself a EXP GDC v8 + 220W Dell power brick and a 1050 Ti from Zotac. i googled a bit and found some ppl saying that the y500 model 1(? - i don't know which one i have) only has mPCIE x1 - so whatever it is they say it's kinda slow. So my questions are, do i only have 1x PCIE, how can i find out and to what "powerer degree" of graphics card can i get, that doesnt suffer from power loss then?! Is a 1050Ti ok für that PCIE 1x? i attached a screen of my nvidia inspector window maybe it helps

Specs: Windows 7 Lenovo w510 12 g ddr3 ram intel i7 Q720 @1.6ghz discreet card: Nvidia Quadro Fx 880M egpu setup: GTx 960 card hooked up via exp-gdc v8 dock via pci express card Using dell 220w psu (12v, 18Amp) Using an external monitor hooked to 960 via hdmi The Problem: Drivers successfully installed, device manager shows GTX 960 and shows it functioning properly. However, no external monitor can be detected. Aditionally, when installing the 960 drivers, it broke the 880M (shows up as error code 43 in device manager iirc). So currently I'm stuck with crappy display on the internal monitor (internal graphics? even though I don't have intel integrated graphics..) and no external monitor detected. I read in the FAQ section that trying to get a dgpu and egpu from nvidia to work is about getting them to run on the same drivers, but it was not clear at all about how to go about doing that. Plus the cards are so far apart in age I'm not sure how to even begin to go about trying to find a drive that will run both. What I have done so far: Disabled pci power managment, this allowed the egpu to be sucessfully detected. Showed up in device manager as "generic vga device" or something like that. Downloaded and installed appropriate nvidia drivers for 960, restarted computer. Computer running on crappy internal(?) graphics card (cant even display full screen resolution) , error for dgpu in device manager (error only goes away after uninstalling 960 drivers and reinstalling dgpu drivers), 960 shown as working fine. Disabled dgpu in device manager (I don't have the option to in the bios for some strange reason, screen shot attached), restarted. Upon restart device manager shows 960 working fine, however, no external monitor detected and computer internal dsiplay still running on crappy internal(?) graphics card (cant even display full screen resolution). Any help would be much appreciated. I feel like I should be pretty close since the egpu was detected and is shown as running ok in the device manager...

Witam, właśnie pracuję nad tym aby ulepszyć chłodzenie GPU i CPU w swoim lapku. Plan jest prosty, zakupić heatpipe'y i radiatory w pełni miedziane odlewane i na razie plan przetestować złożenie takiego zestawu z pomocą kleju termo i drugi lutowany. Wszystko przystosować frezarką aby całość pasowała pod oryginał. będę próbował jeszcze dołożyć po jednym dodatkowym heatpipe do każdego układu. Generalnie laptop jest po wymianie pasty na standardową i temperatury wynoszą dla CPU 48 i dla GPU 44 stopnie C. Zaraz będę wymieniać pastę na miedzianą AG Thermal Grease. Potem pójdzie w ruch Thermal Grizzly Kryonaut i też podam wyniki i oczywiście po całej procedurze wymiany układu chłodzenia. Podam również wszystkie koszty i umieszczę zdjęcia z tworzenie i wymiany układu dla chętnych zwiększyć możliwości lapka. Jak macie jakieś pytania i propozycje jak to można jeszcze udoskonalić to pisać

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 people of Tech Inferno. I am trying to get my laptop withing with an eGPU, i have: Lenovo e540 laptop, EXP GDC Beast 8.4d with mPCIe connector, Nvidia GTS 450, Power X3 450W PSU, eGPU setup 1.30 Initially I would get a black screen when trying to boot with the eGPU connected and when trying with plugging the mPCIe connector in during boot I got this error: "0187: EAIA data access error. 2201: Machine UUID is invalid." Connecting the GPU to an external monitor has no effect. I got around this by putting tape on one of the pins as per this post. After that I no longer get the black screen but windows 7 does not detect the GPU, the fan on the GPU still spins when the laptop turns on and there is a green light on the EXP GDC. I followed the guide on this post but I got this BSOD once rebooting after applying the DSDT override in step 2: "The BIOS in this system is not fully ACPI compliant. Please contact your system vendor for an updated BIOS. Technical information: ***STOP: 0x000000A5 (0x0000000000000006,0xFFFFFA80066BCD50,0xFFFFFA8007103CAB,0XFFFFFA80074FD340)" Does anyone have and suggestions or advice? Thank you in advance. UPDATE: Was able to get Win 7 to detect the GPU when swapping the mPCIe connector while in sleep mode but now I have error 12. UPDATE: Tried the DSDT override guide here but loading dsdt-modified.aml as a registry override causes a blue screen and setup 1.3 hangs when loading the dsdt-modified.aml as an in-memory substitution, it does not hang when the SATA mode is changed from AHCI to Compatibility but it is too fast for me to tell what it does and it causes windows to freeze on boot once it is done with no effect on memory for the next boot. Got it working, just trying to get the laptop to switch to the eGPU now.

Hello everyone! I would like to unlock the BIOS on my laptop. The refresh rate cap is really bothering me and I feel I can't unlock my machines full potential. Any help would be MUCH appreciated! System Info: https://www.sendspace.com/file/4helar

Hey guys just bought a Lenovo Y510P about 2 weeks ago and I still haven't been able to enjoy it without getting a fire extinguisher ready So I have been reading about its faults and what I can do to help ease them. So far it's been a education. I have the 3.05 mod bios, spring mod, new thermal pads, paste and cut holes for the fans. The thing I am trying to figure out is I can see if gpu-z that one of my GPUS have the [MODDED] next where is says the bios version. Can't distinguish weather its the built in GPU or ultra bay. My money is on the one thats built in. So with that said (might get corrected) but lets say all thats left is to flash and mod the bios on the ultra bay gpu. When I try to save my bios in GPU-Z I get an error with some research its a mobile gpu and thus wont save my bios. I am a little confused on the instructions on how to flash that gpu's bios and what steps I need to take in order to under-volt them. I am able to under-volt one of them assuming its the one that says modded next to it. I am a complete noob when it comes to this stuff but charting into unknown territory is well...lets just say challenging. If someone can please give me a detailed guide on what do to I would really appreciate it. Thanks. Joe.

Hello, Lenovo system update installed an update. Also my wifi was unstable so I downloaded the official intel update tool and tried to install the new driver for the wifi. The intel driver installer tried to install the new driver but it was unsuccessful and said reboot required before installing the driver, I rebooted the Z510. Then after reboot it automatically went to the bios. and I exited not saving the changes. ... and black screen. I don't even get the lenovo logo. NOVO button cause black screen too. What I have done: - opening the laptop and unplugging the battery and holding the power button for 15 second and turning it on with AC adapter - changing the ram - removing the hard drive - replacing the laptop monitor with another - plugging external monitor and try it not luck Also, when I turn it on I noticed that the backlight of the screen blinks approximately every 2 seconds, as if it is some kind of corrupted boot loop. please help me I am student and I need my computer and I do not have money to buy a new one at the moment If you need more information please don't hesitate to ask, I really appreciate your help,

Can i replace the wifi pcie slot with an adapter for an pcie graphicscard? or is it whitelisted and i have to unlock the bios? if yes then pls a tutorial... thank you

I have an lenovo z710... i5 4200m GT 740m can i use the pcie port on mainboard to put my adapter for and pcie Graphics Card in? have my bios been unlocked? have the wireless lan card in pcie port locked? how can i unlock the bios?

Hello. I have a Lenovo z70-80 laptop. i7-5500u (2.40GHz). 16GB ram. Nvidia 840m (I believe). The laptop has done wonderful for all of my school CS projects, but I have recently started gaming and I notice a serious lack of graphics power (or to me). I have no experience with building computers, nor do know what many of the technical acronyms mean! I digress. I noticed I wasnt able to run games like rainbow 6 siege or H1z1:KOTK without putting the graphics to the lowest level possible. Even then siege was giving me 22fps when standing still. I also noticed that my Nvidia GPU was not being used. Instead my intel HD 5500 graphics (idk what it is man okay... im sorry!) was being used to process all of the graphics. Long story short. I want to know if i could/should run an eGPU? is it even possible on this model? if so what should i look towards. also any other tips or suggestions are welcome! thank you.

Hi, I'm new on a forum and i didnt see any answer to my problem on forum or googling it. I own Lenovo ideapad 15ISK with GT 940MX 2GB DDR3 and it has serious throttling problems (throttles at 61 degrees, everyone on Lenovo forum are complaining about this yet Lenovo doesnt do anything to resolve these problems) so i decided to modify my vBIOS, or let someone do this. The problem is that i can't extract it. I tried using GPU-Z and got "BIOS reading not supported on this device". Does anyone knows another way to get my vBIOS, or maybe someone has vBIOS suitable for my laptop. I've found vBIOS for 940MX on general 900m series overclocking threat, but its for a 4GB version and for another model of computer ( Lenovo T560) so i guess that i cannot use it? EDIT: When using nvflash i get: " Display adapter's EEPROM ID process failed " EDIT2: I manager to extract my vBIOS ROM file (i think) from Lenovo BIOS update, here it is. My question right now is: Is it right file? I checked on techpowerup and most files for NVIDIA mobile graphics are about this size. And if this is how can i modify it?

I plugged in egpu, booted it up with my gtx 1050 ti and no matter what driver I use, I keep getting code 43. I don't know, but i believe my bios has something to do with it. Can someone plz clearify what I need to do in my case to get code 43 out. Thanks

Hi, i have some questions about my laptop compatibilty for a egpu laptp specs: Intel Core i7-6500U CPU @ 2.50GHz Intel HD Graphics 520 8 GB RAM DDR3 1600 MHz so the first question i have, is possible adapt a desktop graphic card to this laptop? i see in this forum about similar models can do it, but what you do think about? ---------- the wifi adapter is a Intel AC 3165 wich is connected to a NGFF port of the laptop, so i will need the NGFF version of the EXP GDC adapter... i am correct in this??? -------- im think get a GTX 1070 or a 1060, the bandwhich of the NGFF port, and the cpu of my laptop have power enougth to use the 1070 or i'll be better a samller graphic card? --------- other question is what i need to change in the bios to enable correctly the eGPU? your help be useful to me thanks pd: sorry for my bad english :/

I know, i know, i know... @svl7 said it's disabled, @octiceps said it's disabled and many other forum users said it's disabled. I am always want to double check everything and i did it this time too. And i would like to post here result of my research. But first thing first - my PC: Laptop Configuration: Lenovo Y500 SLI CPU: Intel i7-3630QM (2400-3400 MHz, Ivy Bridge, QuadCore) VGA: 2x 2048Mb NVIDIA GeForce GT650M (SLI Configuration) MB: Compal LA-8692P RAM: 2x 4Gb Ramaxel RMT3160ED58E9W1600 (11-11-11-28) HDD: 1TB Seagate Momentus 5400 (ST1000LM024 HN-M101MBB) SSD: 120 Gb Samsung 850 EVO (MGX S4LN062X01) Display: 15.6" LG\Philips LP156WF1-TLC1 (1920x1080) WIN: MS Windows 10 Pro (x64) Also i must say, that i have got UNLOCKED BIOS by @svl7. And for second VGA too. Research It's beginning from @geraldthread about his Ultrabay to PCI-E Adapter for Lenovo Y510p for useing Radeon Desktop VGAs as external VGA. It's performed well with Y510p, but there was zero info about how it perform on Y500 or will it perform at all (now we know that it's no, but it's another story). Unlocked BIOS didn't help with adapter and i decided to dig more deep in re-enabling integrated GPU in Intel CPU - Intel HD Graphics 4000. And new unlocked BIOS give me a lot of new options to play. But important thing is... some of them working, some of them no. So, here is what i am founded. First i go to new unlocked BIOS and saw there a lot new tabs. I go to Advanced => Video Configuration => Special Features This option already was Enabled (Switch Graphic Function) After that i go to Internal Graphic Device and Enable Internal Graphics Device. Then save changes and exit. Laptop is shutdown and after few seconds turn on again. I saw Lenovo loading screen and then nothing when loading complete. Windows didn't start. I am restarted laptop three times and it's started recovery mode. From recovery mode i am loaded Safe Mode and at that point i am finally was at Windows. My first way goes to Device Manager to see new device. And there was new device - Intel HD Graphics 4000. In safe mode windows can't access to it's current status, but there also was no error codes. First time there was no driver installed, but now it's even have last driver! After that i go to AIDA64 Engineer Edition and look what it's show me. It's saw iGPU! So, at this point i don't what to think about it. I can see iGPU in safe mode, but i can't boot with it in normal Windows. Is AIDA64 lie to me or even Device Manager? What do your think about it? P.S. Oh yeah, most menus on Russian language, but i hope your got the idea and trust me. =) It's no fake.

Title. I'm experiencing a few problems including P-state drops when playing mid game and it really hurts my FPS. Thanks in advance. (Y510P SLI 755m) EDIT: I'm on Windows 10

Ok, a little background. I have a lenovo L420 laptop and bought an EGPU adapter via Express Card. I used a Geforce GTX 1050 TI In order for this to work you need to first disconnect any egpu external device and perfrom DSDT override to your system. Very easy guide thanks to user 'angerthosenear' found here (JAVA MUST BE INSTALLED IN ORDER TO RUN .BAT FILE. Other wise nothing will open) Keep in mind step 5 on his tutorial was a bit off. The correct code should look like this: DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x00000000, // Granularity 0x000A0000, // Range Minimum 0x000BFFFF, // Range Maximum 0x00000000, // Translation Offset 0x00020000, // Length ,, , AddressRangeMemory, TypeStatic) /*above this line is only for reference. only copy below*/ QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x0000000000000000, // Granularity 0x0000000C20000000, // Range Minimum, set it to 48.5GB 0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB 0x0000000000000000, // Translation Offset 0x00000001F0000000, // Length calculated by Range Max - Range Min. ,, , AddressRangeMemory, TypeStatic) Restart your computer and confirm your DSDT override worked by going to Device Manager -> Resources by Connection -> Memory and you should see a hierarchy for 'Large Memory' When I was at this point I was still getting error 43. I thought it was a driver issue, but ****** via email thought it was a timing issue with clocks so he suggested I 'Jumpered' the powersupply so it would constantly stay on as long as it was plugged in. So when I plugged my expresscard in the laptop, the GPU would already be powered on. I would first plug your EGPU in your system and see if you still get this error. If so, jump the power supply unit by grounding the greenwire with either of the black wires to the right or left of it. This can be done in many ways, be smart about it. Try to make it reversible. Don't be like me and cut it, splice it, and jam in behind the ground wire. It works, but, not very pretty. This should get yours working. Unless you have a 1050 TI, if so, read on. Download driver versions 372.70 and 375.63 and extract them 1:) - Open the INF for 375.63 Extract the drivers you want to modify using something like 7zip. (with 7zip installed, just rightclick and press "Extract to "/File name here"") Inside the extracted driver folder open Display.Driver. The "nv_dispi.inf" in that folder is what we need to modify. If you can't find nv_dispi.inf, look for "nvts.inf", "nv_dispwi.inf", or "nv4_dispi.inf" instead. 2:) - Your GPU string Search (CTRL+F) for your gpu '1050 TI' Copy these lines, should be 3 if I remember correctly 3:) - paste them in the appropriate place on the 372.70 INF file 4:) install 372.70 Drivers and restart 5:) Now, your error 43 should be gone but your GPU will run like dog sh*t. You need to install drivers 375.63 EXPRESS INSTALL ONLY. If done correctly you will not be prompted to restart. Congratulations, you're done. Took me 3 days to figure this out. If an idiot like me can do it, so can you. I will gladly answer any questions

So i was thinking if i could make my lenovo yoga 500 better since its not very powerful when coming to games i usually play War thunder and i can get 60fps while on minimal and the laptop overheats quite fast so would there be a way how to make it faster like getting eGPU upgrading the components etc. I have also heard that the graphics card and the processor are soldered to the motherboard so i cant change it that easy please im open to any advices thanks in advance

Hello all, I recently picked up a Lenovo T430 as a replacement to an Asus laptop of mine. Soon after it arrived I found that the expresscard slot could be used for eGPU setups. So, I decided to try my hand at it. I have reached a bit of a roadblock though. Laptop Specs: T430 i5-2520m 8gb RAM 120gb SSD Board being used PE4C-EC060A V3.0 GPU: ATI Radeon 5670 512mb I am able to run an external monitor off of the eGPU and it does not show any errors (12) or otherwise. However, after working flawlessly for anywhere between 1 and 5 minutes, the display driver begins to crash every 5-10 seconds, freezing the computer completely. I managed to open MSI Afterburner for a moment before the driver crashed and saw that each time it did so, my eGPU usage spiked to about 80-100%. Not sure if that is relevant, but I found it odd. The 5670 does not require external power and the PE4C is connected to an EVGA 430W psu via the mobo power. I'd appreciate any input anybody with more experience has on this issue. Thanks, Zach
