Sorry but I did not understood you. My problem is to find on the motherbase of LA-C421P the bios (you said mec 1653 but I can't find it). And on the second answer you mean this chip doesn't have SCL and SDA? if that so how can i unlock the bios of this computer?
Many thanks in advance.
want unlock you need know Programming IO MEC or buy one servicer patch.
The problem may not be from the BIOS. above have many BIOS can test and check hardware..

I know the history of the laptop ... the laptop is correct only in one service they deleted the contents of the chip
But above there are a lot of BIOS you say all it doesn't work, but bios lock above 100% work you can test

You can try adding additional BIOS locks that customers send to unlock requests

Listen you mistake something (25w128fv is work 3.3volt)Or (25w128FW is 1.8volt) IC

Hi, I have a problem with an L560 laptop. The client says that after the bios update, the laptop died and no longer gives an image. I wrote several bios on vinafix, "Clear me L560.bin" with this dump the laptop starts but does not give an image, only 4 beep signal. I put a flash with operating system on it and the laptop crashes but I have no image. Can someone help me with some advice
have GPU or not ?
If all the BIOS doesn't work next you need to double check all the hardware, they could be faulty at any time
