Lenovo t560 lan fix after loaded bios
Hello
I have 3 t560 where I reloaded the bios ( Orig+$0AN1K00.rar , from here ) to recover from non booting or slow booting, al was fine and update-able but seems that with all of them has a intel lan adpater what is not able to start, new drivers or reinstall does not help.
tried to reflash the gbe file with original mac but that does not make the different.
Has anybody a tip what to do to get onboard lan working again ?

HP Pavilion x360 - 14-dd0505nd gpu freeze bios ?
Hello,
I have "repaired" this laptop by replacing the intel me with the newest stock bios from hp. originally the laptop was comming on but no image, after the bios mod and long without battery the laptop powered on with image and loads windows.
While installing the drivers the system keeps freezing (no bsod) while installing the intel 610 cpu driver, screen go black and stuck, turn off and on in save mode it works, disable the gpu driver wil result in "working" system.
Could this be related to the bios ? I do not have history of this laptop....

Re: Legion 5 15IMH05 Bios
Is there a tutorial about adding or edit the DMI ?
based on the comments assume you can't clone a working bios over a corrupt one ? (with programmer )
thanks in advance....

Re: AMITSESetup Decryptor
thanks for bring the python and the windows exe !!
I have a asrock mb ami with stored password, both tools are unable to find password.
If I look into uefi tool I can find (multiple)
4E5641523800FFFFFF820B414D495453
4553657475
(amitsesetup)
The one with data in it starts at 0020 and 01 is at 0030
I understand it should start at 0040
And my length is just over 1 line in uefitool
On the main board I see a other small windbound chip, maybe I am unlucky and is it...

Lenovo yoga 330 powers on no image
Hello,
I have a Lenovo 330 (Yoga 330-11IGM Laptop (ideapad),Yoga 330-11IGM, Flex 6-11IGM) wich powers on but no image and only consumes 1 watt at the 230v adapter. It does charge the battery with or without ac no diffrent.
YOGA330+MB_V06
I measured the coils:
U6002 > 3,3v 2,4k ohm
U6001 > 5,2v 300k (and less) ohm
U5901 > 12,9v 114 ohm
U6102 > 0v 19 ohm
U6104 > 1v 77 ohm
U6103 > 1v 27 ohm
U6105 > 1,2V 222 ohm
at U6102 is a mosfet apw8707 located, I attach image....

Re: Lenovo 320s no power no led
update
I replaced also q5902 because it was shorted, for sure diffrent then the other ones.
Result was no flashing red led anymore while pluging in power cable.
I replaced the isl again with new one, and now the board is fully functional.
So the isl broke (already) or was not good solderd.
Now it does turn on on power only but also charges, all lenovo tests are green/OK.
First succes with real chip replacements.
case closed and @mon2 thank you very much

Re: Lenovo 320s no power no led
I replaced the mosfet and the isl. but is does not turn on.
with the mosfet there was no diffrent with the isl you see a short red blink when plug in adapter. so that is new.
but won't turn on with adapter only nor it will charge.
it tries to start but shutdown

Re: Lenovo 320s no power no led
ok update
replaced d5902, was a bit smaller, and due to my non expierence some other components moved due to air or movement, but all fixed to it's place. I now also see that the resistors are a bit bigger, I think I need need new glaces haha
therefore always make pictures.
On battery mainboard turns on and windows is loading fine, with ac adpater plugged charge led is white, does not consume a lot power, windows does show charge indication and see a bit v increase (triggle charge ?)
system on at battery and adapter,...
