[dr.thodt]

Hi,

I have an HP 15-ec2531nd here which does the following:

- BIOS works.
- All self tests pass, except smart pin. Not even with another adapter connected.
- RAM is ok.
- RAM slot pins are ok.
- Battery is ok.

Whenever I want to boot Windows from m2 SSD system switches off.

Got a MacBook Pro M1 Pro 16'' to rescue immediately after liquid accident - I got it in less than 30 minutes after the spill.
It got spilled from behind when the laptop was closed. It mostly affected the rear of the mainboard and the bottom of the LCD.

I quickly took it apart and washed the liquid residue off the mainboard.
The area around the UP800 had some light corrosion, but it just washed away with some IPA. Other areas looked undamaged.

The mainboard got a thorough cleaning, as did the top case and LCD connectors / cables.

Now the laptop...

Hello everyone,


I'm new to the forum and looking forward to learning something new.
I got a Lenovo Thinkpad X1 Carbon Gen9 (with intel CPU) on which the USBC ports were broken, these are now repaired, I have reinstalled the notebook with Win11 and actually everything works, but it has a bios supervisor password.

is there any way to read out the password, or install a new bios? or any other methods?

as I said, I am an absolute beginner and need to get an overview first




Greetings to all...

Plugging the power in will turn on the backlight after about 5 seconds and then immediately shuts down.

If I unplug either of the two cables with the yellow outline in the picture the backlight stays on and the startup sound plays but no image. Any ideas how to proceed with this please?

Hello adventurers

I have this board and it came from a friend with a shorted EC.
I have ordered a new one and replaced it.
Now i have 4 Milliamps draw on pluging
3VALW and 5VALW present (i know nothing about RSMRST and ECRST because web only has boardview for 16r3 and this modell looks competly different)
For EC flash i need KSO3 KSI4 KSI7 KSI6 KSI5. These are all 3.3v EXCEPT KSO3 is 2.2V
I have checked the FFC cable connections and they are OK.
I have removed and Reballed the IC again, but no change.
Do you have idea why EC not responding...
