Surface Pro 7+ LTE 1961 MP5 L MB, looking for schematics

Thank you. Sadly, no change - still 3,6. -
HP Pro Mini 400 G9 - Led code 3/6 Processor does not support an enabled feature / disable AMT in dump?
Hey,
I got HP Pro Mini 400 G9 waiting for a long time for a CPU. Bought I3-12100T which is on supported list just to receive code 3,6 which says "Processor does not support an enabled feature".
After research I found this is most likely due to all the management stuff being enabled in BIOS (it has vPRO essentials I5 sticker so that is very likely) where 12100T definitely does not support it.
Unfortunately I wasn't able to find any friend who would have and lend me their CPU to fix that... so the question is, can this be changed at bios dump level?
I attached... -
It worked, thank you!Leave a comment:

HP 400 G6 DeskMini broken bios - never ending boot loop - fix request.
Hi,
I have HP[B] 4[/B]00 G6 DM which is not booting - it will spin up for like 30 seconds, then turn off for a few, boot again... and it goes on forever.
Can anyone check this dump and maybe attempt to repair it?
SN is 8CC1340PC8. Board is "Missandei-AUD Rev B Model F91" DAF91MB16B0Hi,

Hi,
Panasonic FZ-M1. Asks for password on boot.
This is Haswell so old trick with AMITSESetup doesn't work.

No such option visible in menus. But there's i2cTouchPanel DXE driver, as well as some strings like [I]Touch Panel Support Enable / Disable exposing of HID (PNP0C50) in ACPI ASL code to OS[/I]... so not sure, maybe?
Nothing in SetupUtility though.
On the other hand see the attachment. Left is Intel variant, right is AMD. And indeed pins 1-10 are open line, not even ground on pin 1. Thus even if TS support existed at some point I don't think it made it into a final PCB.

And unfortunately disappointed. There's no trace of touch screen except on 1st page
LCD connector is the same as on intel model, just touch screen pins are not used. And there's non used I2C lane on CPU.
Wonder if that was removed during development, or just editorial error...
Oh well, no touch screen for me.Leave a comment:

Lenovo Yoga Slim 7 14are05 DA0LS3MBAF0 - looking for schematics.
As in topic, I'm looking for schematics (and boardview if available) for Lenovo Yoga Slim 7 14are05. Board model is DA0LS3MBAF0.
Turns out AMD variant never had touchscreen option while Intel had. And cover page of that schematics available on Google suggests it supported it at one point.
I happened to have intel TS display cable and a touch LCD... wondering what's missing to enable it (display works fine, but without touch)... -
What are you trying to do? What decoupling caps? Where did you get 5v and 1.8v?
For LPC you short data pin(s) to ground, not up...Leave a comment:

As written in another thread, L14 G2 AMD, NM-D391 + NPCE68B works fine

That was likely incompatibility between bios image I flashed and EC, or the image was somewhat broken.
Reflashing this one clean didn't help. However I still had original BIOS backup (which was not booting), decided to flash it - first boot attempt was no signs of life except power led, 2nd - it booted fine and without that error

I know what I'm doing hardware-wise, just don't know what the software was doing.
Turns out I was looking in correct place, just my timing was wrong.
I can confirm it works on L14 G2 AMD, NM-D391 Thank you!
I won't spoil how - that's for you to share
Now I'm getting "boot configuration has been recovered by restoring backup" on every boot. No amount of resetting things, setting and removing passwords, etc. help with that.
But the machine was dead on arrival and I revived it with bios found on Badcaps - thus I think I need to grab a working...Leave a comment:

In the past I tried to block communication from KBC by pulling down / up some signals but without success.
I have L14 G2 AMD, NM-D391 20X60S1Q400 PF-3ML8Y4 (assuming sticker / back plate comes from that unit).
It has the bad combo of both supervisor and power on password enabled.
Unfortunately I have only access to RT809H, so would definitely be interested with that method....Leave a comment:

Looking for schematic / BV - Dell Wyse 5070 / Wistron San Bernardino 16561-1
Hi,
I wanted to modify 5070 board into 5070 extended variant (one with PCIe x4 soldered in) but from a few low quality photos I'm fairly sure there are more components missing than just the PCIe connector. Do any of you happen to have Wistron San Bernardino 16561-1 schematics and boardview available? -

Thinkpad L14 G2 AMD (NM-D391) Power On / Supervisor password
Hey,
I just revived this motherboard (fixed no POST, thanks to a BIOS from [URL="https://www.badcaps.net/forum/showthread.php?t=119595"]this thread[/URL])
Now there's a supervisor password required on power on. It is stored likely in EC, which is Nuvoton NPCE68[b]B[/b]PA0DX (sometimes misspelled as NPCE68[b]8[/b]).
I've seen some success on reading this chip in thread for Intel version of this laptop [URL="https://www.badcaps.net/forum/showthread.php?t=115521"]here[/URL].
I have access to RT809H programmer. Is there any chance of...Last edited by kitor; 09-12-2023, 08:49 AM. -
Re: Dell Latitude 7390 - all power rails up except VCC_GT, no image.
Funny thing - even though TBT3 controller (JHL6340) is broken, it kinda works.
For future readers - there's a schematics available for 7280 (LA-E121P) which is based on older version of the same project - and TBT3 part is almost identical.
Issue is with 3.3V_TBT_SX (or VCC3P3_SX) which is to my understanding suspend power. After reconnecting PJP6, TBT3 IC gets quite hot instantly (even at suspend) but TBT3 bus works - I connected to a dock with no issues.
Interesting design...Leave a comment:
