If you can read and write from the chip it is still good (do a verify to make sure it stores what you wrote). Try a few things. Did you do a full reset of the bios before trying to turn it on - remove CMOS battery and short the terminals (don't forget to remove the internal battery also before you work on anything). Report back.
If that doesn't work, did you make a copy of the original bios? What happens when you flash the original dump. does it boot up? If yes, then you don't have the right unlocked bios version.

Are you saying you are getting perfect output on an external monitor but not on the internal monitor? Do you get bios screen (non graphic) ?Leave a comment:

Ok, so figured it out and will post the solution in case someone has the same issue. Unlocking the 32MB file did not to the trick. Used RcUnlocker on the 16MB chip and that did the trick it is now unlocked. Many thanks to all of you and thanks Peste!...Leave a comment:

Not sure if this is important, but when I boot and press F10, before getting the Bios Administrator Password screen, I get this screen which say PROPERTY OF GHD then the HP logo and then the message Protected by HP Sure Start.
I tried looking for the string "PROPERTY OF GHD" in both the 16MB and 32MB files but did not find anything. Not sure what to try next?...Leave a comment:

Need help interpreting schematic of Lenovo B470 motherboard
Hello everyone,
OK, so here is my issue.
This Lenovo B470 motherboard I am troubleshooting died and I identified it is the discrete Nvidia graphics chip that has lost it's ways!
So I removed it and now I am trying to change this motherboard to use UMA graphics, but I am having an issue interpreting the attached diagram. I have a 10K resistor in at the R2013 position and another one at the R2012. R2010 and R2011 are empty.
The motherboard starts, the fan spins but no display. It turns off by itself. I restart it and it does start but stays on...Last edited by rddube; 08-12-2024, 03:16 PM. -

Can anyone fix this bios? The file size is 8192 and I did get the bios region which is 3584 bytes and merged it into this file but that didn't fix it. Same symptoms, laptops starts, fan spins for about 15-20 seconds then stops and nothing on screen. When I turn it off, it turns itself back on, all by itself. Many thanks to anyone who can help!Leave a comment:

Hello,
I need some help in fixing this corrupt bios on a Toshiba Satellite Pro A50-A. Laptop starts, lights flash, fan starts spinning for about 15-20 seconds, then stops. And starts over again. When I turn it off, it turns itself on all by itself.
Serial number is (E175457H)
Attached original bios dump.
Many thanks,
Raymond...Leave a comment:

Toshiba Satellite Radius 14 Bios extraction help
Hello,
I am trying to extract the Bios for this machine (I bought this on Craiglists and it is a Toshiba Satellite Radius 14 with no serial number and the Bios chip is blank!). Attached is the file and I followed the instructions SMDflea suggested, but when I run this, it doesn't create a .com file it creates a .rom file?
Please help and thank you!... -

For some odd reason, every time I turn it off, it doesn't want to turn back on? I have to unplug the CMOS battery and the main battery to get it to start up again. Any thoughts?
Tks!...Leave a comment:
