I tried couple of bios that are listed under older E5470 threads but none of them worked.
I am getting black screen with power button light on. No other indication.
[B]Condition Before Bios Flash :[/B]
- Was stuck on booting into Diagnostic Boot Menu for some reason and no key combination worked at all. After little bit of research I concluded the faulty bios.
Oh BIOS is empty, I think that's the issue. I am not able to read the chip now , It seems damaged. My programmer reads another Winbond chip but not this one.
I have old bios 1.13 backup. I am attaching here.
Requested information :
Model : HP EliteBook G3 Touch i5 6200
Logic Board : 6050A2892401-MB-A01...
I did bios upgrade 1.51 after password unlock. It was working fine but after couple hours it started behaving weird. So I thought it might be soldering fault and tried to heat up the chip with no success. I was able to backup 1.51 backup from the chip but I feel that its corrupted based off comparison with another laptop backup.
I am attaching it here.
So far I tried older bios version 1.39 unlocked backup but nothing worked.
Same LED blinking pattern that shows logic board failure....
My Laptop : HP Elitebook 840 G3 (Touch version)
It was locked so I successfully unlocked it and updated bios to latest.
somehow bios chip was not properly soldered so it was showing flashing LED.
Now I soldered it and but it failed.
So I took same winbond chip from another board ( matching ) , flashed it with my backed up bios.
Now laptops starts with blank screen and runs the fan very highest speed for a while and then it goes off. Keeps on repeating the same cycle.
Not sure...
I recently got EZP2019+
I am trying to read Winbond W25Q128FVPQ but always getting not detected message.
I am using SOC8 pin socket that came with programmer.
I am selecting W25Q128 inside EZP2019+ software available chips.
Is there anything I am missing ?
Thanks
