BIOS Upgrade Problem
Hi everyone,
I have a strange problem with my laptop Dell Precision M6800 when upgraded BIOS.
- Here's my problem:
A month ago, my laptop Ethernet has problem with connection, so i broguht my laptop to the store i bought for warrantly. At the time, i've already upgraded my BIOS version to A26
Few days later, after the store returned my laptop, i opened my laptop to check, then i saw my BIOS is being downgraded to A5. So i decided to upgrade it again
So i downloaded the program M6800A26.exe again and run it to upgrade my BIOS
Before i upgraded, i've charged my laptop
After my laptop rebooted, it booted straight to Windows OS. Nothing happened, no errors, no upgrade, nothing!
I did repeat that step few times, then tried the usb flash method to upgrade BIOS but not work. Still nothings happens
Looking forward to all your comments
Thanks a lot

Welcome to the Dell Community @tuan.nguyen09
Did you try an intermediate version first???
Like A9 or A10???
Best regards,
U2
NOTE:
The "Warranty Repair", did they replace the system board???

Hi U2CAMEB4ME,
Maybe i should record video for more details. But in brief, my BIOS cannot upgrade no longer
I do not know where they replace or not? But this problem happened when they returned my laptop after warranty

Answer your first question,
Yes i did upgrade from A5 -> A6, nothing happened
P/s: when i bought the laptop for the first time, i upgraded my BIOS directly from A5 -> A26. The result was successful

i hope you don't get my wrong
if you upgrade your BIOS, your machine must restart. But after the POST no upgrade information appear on the screen. But in stead my machine boot straight to Windows like i have not run program upgrade my BIOS
