Re: dell latitude e7470

Ok - Here is the bios removed from the board and it looks the same as the one I did on board. Not sure what I am doing wrong. I am using CH341 programmer and I tried with Asprogrammer as well as NeoProgrammer. I picked winbond 25q128fv, hit read and then save. Then zipped file.

Both files are not Identical and they are not good.

You said that you have tried another files, is that means you lost the original backup and there is another file on the chip?

Re: dell latitude e7470

No, I never lost the originals and I put the original back on the chip after trying the others. Here are some other backups. Backup 1 and Backup2 were taken with clip and different software. I never modified the originals either.

You didn't take the proper backup from the chip at the first time. However, I attached a BIOS for your device and you can try it.

Use NeoProgrammer and remember to select verify the chip after flashing it.

Re: dell latitude e7470

Wow! I am amazed. It restarted a few times and then I saw the display for the first time. Then I set it to UEFI and it booted windows and then restarted and updated firmware by itself. I was beginning to think that this wasn't a BIOS issue, except I had read other posts which had the same issue. What causes this to happen? My client said he used it one day without issue and the next day it would not power up. I guess my mistake was reading the BIOS while it was in circuit, even though I had the battery disconnected. The CMOS battery was still connected though. At the moment, it appears that everything is working perfectly. Thanks again for all your help.

Try this one,give it a few minutes to statrt/restart. If it boots up ok then run the latest bios update from dell to update the bios and EC .If it doesn`t make any difference the problem isn`t with the bios.

thanks bro works 100% no delay
