Hello everybody

I have a Jumper EZBook x7 with no picture, caps lock no working. The laptop starts, the CPU gets warm, after a while the fan starts spinning but nothing on the screen. Current consumption is stable, about 1 amp. I can't see any short on the motherboard (CPU resistance very low but mosfets seem OK).
I suspect a bios issue (or a problem with the onboard RAM), but can' find any bios for this model. I already try to clean the ME Region, but without any success. If someone has this laptop, can he please share the bios? Please find attached the dump of my original...

I think i found the answer : double N channel mosfet DMN2004DWK. Can be useful for others... :_)

Here are the backups (the 3.3V doesn't reach the chip of the main bios, but only the chip for the EC because the mainon signal is missing. I hope that the EC firmware is the only one problem...)

Thanks for the reply!...

Hello everybody!

When my father bought his first computer, i was 16yo. I'm 57 now...
At the beginning i hated this machine, because he spend a lot of time with it, and not with me!
I bought my first one in 1997, it was a Pentium 2, 350MHz. When it broke down the first time i asked to someone to repair it, and waited two longs weeks.. The second time i decided to repair it myself, and it was for me very pleasant! Now i spend a lot of time buying and fixing (or not...) dead laptops (and other devices)...
