Have you flashing it with an external programmer?
If not, try it this way.

Re: Lenovo t510i bad bios flash

Yeah thats what I am doing I dont rely on these Crisis way using floppy or usb key. I removed it from the board, the problem is there are 3 files in the Lenovo bios package 1 compressed (1mb ish) and 2 uncompressed usually named xxxxx.FL1, xxxxxxx.fl2 and slightly different number to other 2 also ending in .FL1 both files around 3mb, so I followed the instructions for decompressing the compressed one it then becomes 3mb and I have tried flashing all 3 without success.Camera led flashes, fan spins unit turns on it itself and then off again pauses for a a while then does it again. I know the unit worked as I recently serviced it. But it died during bios update a few months later. The schematic I have (wrong version one) shows 2 spi chips 1 bios other EC controller, problem is I can only find 1 IC the Spi1 chip no sign of the other one. I can only assume then there is no seperate Ec controller on this model and SPI1 is the correct EEprom.

Re: Lenovo t510i bad bios flash

in your case there is no other way than to find dumps for these two chips. what is the size of your bios (1mb 2mb 4mb or 8mb) ???? because 3mb is not a correct size.

is yours I3 i5 or i7 lapy ????????

Re: Lenovo t510i bad bios flash

Its an i5 and also in the bios package there are 3 files 2 cannot be decompressed so Im assuming they are already decompressed these are 3mb the other 1 is 1mb and when decompressed using the utility (e_bcpvpw) it becomes 3mb. Its an unusual system they use. Yes you are right if I could get a dump of the bios and EC that would certainly do the job.
Thanks for your input.
