Ok, well if you are convinced you have the right Bios, then the only other thing is that you have a hardware problem. "so i replaced from the fully working 7310 the bios chip UC5 and two other winbonds UT2 and UT9 but still the same behavior." means you used hot air I suppose - might have inadvertently unsoldered a resistance, capacitor, or something in the process. Check around those chips to see if you might have something that is misplaced. If you need help, post some clear and close photos of the areas you worked on. How would you rate your level of skill in using hot air ?... -
This is where I think you are wrong. The 7310 bios might not be right for your 7410 laptop - if it works in the 7310, doesn't mean it will work in the 7410. Try and get a 7410 dump, compare it to your original (use hex editor to compare). Pretty sure you have a bios issue....Leave a comment:

Not sure I understand you, if it's working with a swapped bios chip, just copy the chip and get on with it?...Leave a comment:

So ? Doesn't matter. You want to fix it or just abandon? Cleaning the ME of a Bios has nothing to do with the CPU brand or type....Leave a comment:

Ok, so read this thread [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/92419-lenovo-thinkpad-e14-bios[/url] - go in the same section and upload your original bios and ask someone to Clean the ME.https://Ok, so read this thread [url...nd ask someone...Leave a comment:

Had that happen to me once and it turned out that it was the power supply not providing enough current - can you measure the current coming from your power supply? If not, do you have another power supply you could test with, one with higher amp rating? Also, I noticed in the photo you have circled a small capacitor that heats up. Did you try removing it?Leave a comment:

Did you get your programmer?Leave a comment:

The only reason I am asking is that removing the chip and the laptop boots doesn't mean the chip is bad, it could just be making the connection to a shorted area of the MB. You've got voltage coming in on pins 1, 2, 3, 4, 5, and 32 with a bunch of capacitors on those pins, check that there is no short there with the chip removed. Check all other pins except 33 which is ground to make sure there is no short anywhere else. There is another bunch of capacitors on the output lines (pins 20 to 25). Been there, seen this as you replace the chip with a supposedly new one (depends where you ordered it)...Leave a comment:

Was your fan plugged in when you checked the mb with a thermal camera? Could be your fan that is shorted? Also, how did you measure the output pins with the chip already removed ?...Last edited by rddube; 02-26-2025, 06:25 PM.Leave a comment:

You might want to take a look at the schematics and try and find in which area the chip is. Could be one of it's outputs that is shorted ?

So what happened ?...Leave a comment:

Sounds to me like a corrupt BIOS, so I would get a CH341 adapter, reflash the BIOS (you can probably get a dump here on Badcaps) and I think you should be back in business. Make sure if there are more than 1 bioses to flash both. Let us know.

No unfortunately, same behavior. A burst of fan spinning this time, with merry go round of keyboard colors, power light green turning off and back on a few times then normal fan spinning, power light still looping and nothing on screen....Leave a comment:

Hello friends, need a little help with a Razer model RZ09-01952W71 which is behaving as if it is a bios issue. When I turn it on, the fans spin very quickly about 1 second, then the keyboard goes into a ever changing color pattern and the ready light flashes very slowly green when plugged in and red when on battery. Then fans start spinning and they just spin no post.
Attached are the bios files U50 is the main bios I think, I did try another version (in fact 2 other versions that I got in the forums but no luck). U49 is I think EC, and I was able to try another version that SMDFlea...Leave a comment:

The 16mb chip is on the other side of the motherboard, so you are going to take the motherboard out. I always desolder the bios they are so easy to desolder and use one of these attached SOP8 to DIP8 (I have different sizes) and resolder onto the board. You can always use the little board that comes with the CH341 programmer - just make sure you've got pin 1 on pin 1, etc. I never use the clips they are junk as far as I'm concerned....
