I have a Dell Inspiron 3721 and suddenly the laptop have a problem. When i turned it on is gives no screen and only one beep and repeat it.
I search and found the this could me a bad rom and that it could be fix with a new bios flash.
Suddenly i had screen again and flashed the new rom. When it reboot i saw the message the it was the wrong one and that it boot again the revert to the older on.
From that moment the screen was gone and only the beep.
Tried:
Reset BIOS (remove CMOS battery)
Remove accu power AC and hold powerbutton for 30 sec. Discharge
Tried booting with END key / CTRL-ESC etc and plug power adapter and all other tips i could find.
So now found the right BIOS file but because i have no screen i could not install it.
Tried it with bootable USB disk and BIOS file as Dell mention but noting happens.
So i now order https://www.amazon.de/-/nl/gp/product/B0...prod_image and hoping to get it end of this week.
But when i extract the file i don't get the bios file i think to flash it.
So hoping for a little bit of help with it when it receive the KeeYees SOIC8 SOP8 testclip.
How the get the BIOS file from the link below (3521A16.exe).
bios: https://www.dell.com/support/home/nl-nl/...on-17-3721
extracting gives and error but do get files. Trying the extract isflash.bin result in few files. One file is large but is .data as filename. So i think the is not the right way.
Update:
Received the KeeYees SOIC8 SOP8 testclip voor EEPROM
I think i have mange to extracted 3521A16.exe to get a bin file. When i open the bin with HEX editor it looks like a bios file.
But now need the create a dump file from the EEPROM this weekend and then the hard part i don't get.
So Questions i have
1.What to do the get the old info from the dump file into the new bios file. Seen lot of youtube but most are in Hindi and not very clear to me.
2. How the know the exact file size you need. Is the size of the dump file the size it needs to be for the new bios file.
3. The KeeYees can read 24 and 25 serie EEPROM but how to know which one you need.
p.s when i create i topic i have no big screen to type the message here. It is all messed up. Tried it with different browsers. Check picture.
So sorry that my message is a bit messy.
