Yes, some of our previous discussion on doing the BIOS chip swap was replaced. Anyway, I opened up the system to look for these BIOS chips as indicated by @Lizzo and believe these are the ones:

If Lizzo can confirm that would be great, also any tips on performing the operation would be most appreciative. Ie: specific step by step instructions and what tools are needed.

Sorry for not being on in a while, but those are in deed the BIOS chips

I changed the multiplier of the third and fourth core to 27 and undervolted by -60mV. Where do I get this stock bios file named Yx01.bin?

Thanks so far

Just download a bios from the Lenovo website for your model, use 7zip to extract it and then you will see a file with the extension ".bin" and rename the file to Yx01

Hey Guys,

I've got a big problem! I changed the voltage and the multipliers of my CPU inside the menu of the modded BIOS (I know that was so stupid) and now it won't boot. If I press the power button the display doesn't start but the LEDs of the keyboard and the power button turn on. If I remove the AC power there is a beep sound.

I HOPE for help.

Thank you guys

Lol changing the multiplier won't cause that issue... Changing a setting pertaining to the video card (like I did) will cause that issue. As I posted, the solution that worked for me was taking it apart, and exchanging places of the primary BIOS with the secondary BIOS then running the emergency BIOS of recovery method of putting a stock bios file on a flash drive (named Yx01.bin) then plugging in the flash drive (fat32 format), removing all power sources from the laptop, and then holding down fn+r then plugging in the power adapter and finally pressing the power button while still holding down the fn+r keys.

I solved it without chAnging the board and I have no problem actually helping someone else.. USB wasn't even booting and after doing some research it came to me. The laptop has a DUAL BIOS, and the purpose of the secondary BIOS is for situations just like this.. I swapped the primary with the secondary bios, then I proceeded to do the emergency recovery with fn+r then plugging in the laptop and pressing power... I'm happy to say that I now have a working laptop. Now then, to my question: can someone tell me how to flash modified clock settings to the internal 750m? I've noticed that the 305 modded bios has got a higher than default clock setting flashed to it.

So NO one even bothered to help me solve my issue... But its cool, I got it sorted out by myself. I have a another question that the helpful people can once again ignore. Can someone tell me how to flash a higher default clock settings to my internal gpu? (I have the secondary 750m gpu from a 510p in my 410p and its working fine)

Hi, I know you probably get this a lot but I fruited up...being a man about it. I really fruited up, and I need your help. I'm not sure if you would be able to help, but I'm still asking.. Today I decided to flash the bios mod to my laptop because the WiFi card that came with my y410p disconnects every few minutes and I wanted to change it. I flashed the mod,everything went fine and I went tinkering in my bios and changed the igpu size and now my laptop powers on but the screen is blank and the keyboard lights up. I have followed the link posted many times to recover the bios and I have the files on my flash drive and my procedure is this.. Inserted flash drive with the bios files renamed accordingly, its formatted in fat 32 (tried all 3 ports) then plugged in the power cord with the battery out while holding fn+r (also tried x and the flash drive would only blink once as I powered it on but nothing flashed. Please direct me as to what I can try or what key combination worked for that y410p. I have read through the posts but no one really talks about what worked for them.thanks again

Yeah orc i try it, but nothing just after 2 second the laptop shutdown itself and nothing more. Not even a single lenovo logo or something. The keyboard start lightning the hdd spin up then the all system just shut down

same here/... and now, i'm not even gettin power

I do the same but Still nothing. Its just unbelivable one bios settings can damage the whole machine like this

Anyone knows where I can orser a botherboard? Or here I can buy the bare case with motherboard (or something like that)

Try unplugging all drives from your laptop and see it changes anything during boot.

I disconnected everything includung the hard drive and I even changed the ram...ughhhh... Think I may need a board

Hey the bios mod worked great, but I have a problem... I changed my settings in my bios afterwards and my computer powers on for a few seconds and then powers off. It does that for about five times and then powers on and stays on but the screen stays blank. So I'm wondering if someone can tell me how to reset my bios to default or flash it back or something. And if it can't be done, can I be directed to where I can purchase a board? Thanks in advance. And again, wonderful mod.

clevo always seems to be the better option to me

i have the same configuration on my y500 and i don't have that issue... well, i mostly play league of legends and in that game it has on screen fps that shows me it's always locked at 60fps when vsync is enabled

i used a copper coin between my gpu and my heatsink with thermal paste and it lowered my temps significantly (i was advised not to do it and it would not work) my temps were around 68-74C

buy anything but a sandisk ssd

notepal 3 is awesome use it daily and it keeps laptop nice and cool

i had the notepal 3 myself.. i would recommend it

nice, perhaps i can repaste the internal gpu. it for some reason always runs kinda hotter than the caddy 650m
