Re: X210s

How are you getting the CPU temperature so high? My fan is nearlyalways off and there is no heat on the bottom or side from average use -- fan only kicks on if I'm doing a lot of heavy work, such as compiling. Even during hours of repetitive memtestx86+ runs, the reported temperature was maximum 45...

Re: X210s

This is really strange since i have already compiled for ~10h on it and never encountered any problems. Maybe the microcode fix was applied to your board already? Mine is part of the third batch (delivered from the factory in Dec 2018) and perhaps they forgot to apply the patch to the third batch. ...

Re: X210 fan and battery communications

Not really an answer to my questions, but https://github.com/erpalma/throttled/ can adjust CPU temperature ceiling and display CPU power consumption (among other immensely nice things) that can be used to tune the battery performance of X210 and other newer Thinkpads.

Re: X210s

If anyone is using their system without these issues, which RAM are you using, and what BIOS settings did you tweak. I know you must have tweaked something since I know for sure the default BIOS setting is to treat all SATA devices as Hard Drives rather than SSD. Also, what distribution and kernel ...

Re: 51nb motherboards and spill protection?

Taking care and steps not to spill anything around the laptop would help too. Fortunately I never had an accident around a computer. Beer and drinks are placed in a way that when, not if, it spills there's nothing of value that it can damage. On airplanes the laptop, tablets and phones are stowed a...

X210 fan and battery communications

Hi there, i just got the third batch™ X210 kit, and it seems like it cannot report battery current in Linux (0 via ACPI where X230 reported correct values) and neither report nor control the fan speed. The former makes me unable to optimize my battery life, and the latter results in the CPU frequenc...

I thought you mean F1 on the motherboard. It is blown and you should replace it.
Yeah you were right, my roommate decided it's a good idea to fiddle with it when the battery was in.
I've replaced F1 and it works, thank you.

Re: Upgrading X220/X230 to FHD 1080p

VBL20 is responsible for the backlight power. Given that you bridged F1, either your solder bridge is blown or the copper track is blown somewhere on the motherboard. Two things to keep in mind: 1. Do not bridge fuses I've bridged F1 on the mod board and desoldered AUX power as you've suggested ear...

Check if BACKLIGHT_ON, PANEL_BKLT_CTRL and VBL20 are present on the LCD connector.
VBL20 is zero, was too frightened to try touching the others due to their size.

Okay, the backlight on my X230 have stopped working altogether. I don't have the aux power wire soldered and have F1 bridged over. I have a soldering iron, st-link, multimeter and a crappy digital scope. How do i find out what's wrong?

Are you sure it's not a soldering issue? eDP cables failures are extremely rare unless you intentionally abuse them.
Yeah, you're right: after poking the PTHs thoroughly with a soldering iron it works flawlessly. Thanks a lot for the suggestion!

@L29Ah: The panel is powered exactly same way as the stock one. The only difference is that VCC3P, which is used to power stock panel logic, is not used by default (although the adapter board is designed in such a way that it can power the FHD display logic from VCC3P). Does this mean that 3.3V for...
