I recently purchased a T480s and after taking it apart to do a badly-needed clean, half the screws inside are missing, e.g. no screw for SSD, only 1 for the battery, various ones for the connections etc.

If I buy a specific set for the T480s, they're like £35, so I'm thinking of buying a large generic set from ali - what sizes do I need though?

M2 x 3, M2 x 4? for both the normal and the 'fat head' shorter ones?

Are there any others?

Also, bonus question, the previous owner did something funky with the screen and the sides don't seem to be pushed in equally all the way around - can I simply just apply force and push the screen into its housing so the sides align up equally, or do I need to actually take it apart?

I was one of the lucky ones to receive their C.H.I.P. computer hardware back in the day:

https://en.wikipedia.org/wiki/CHIP_(computer)

It's just another SBC ala the Pi world of machines, but it had a few features I really liked:

• was physically small
• was powered entirely by a USB port that worked off of my laptop
• ran Debian/Armbian style Linux distros
• had a fully functional USB OTG console (this is especially important)
• had enough RAM for general hacking, but nothing hugely special

Too bad Next Thing Co got over ambitious and ran themselves out of business because their design was great, though it did run really hot at times.

So, I need a replacement. My major use case is while traveling. I like to do small SBC-based projects on the go. This means on trains and airplanes, coding and working with electronics/sensors. My new job starting in a month will have me commuting on a train for an hour twice per week, so I'd like to find a new board I can work with.

What boards can people suggest? I've done some searching and I have a few in mind, but I'd like to hear your ideas.

I do know about the RPi Zero 2 W, but I've never liked the RPi Zero boards and their form factor makes me sad for some reason. Mostly, they're unweildy given the off balance design. What else is out there? What's worked for you?

Hi all,

I had this laptop (Lenovo Carbon X1 Gen 6), and when it had Debian, it would just go flat on sleep, and even when powered off. So strange. I checked all BIOS settings etc, but could never figure it out.

I moved it to Fedora, and it was perfect. Battery life was boosted like crazy, acted as it was meant to.

However, I have tomove away from Fedora, due to them dropping X11 (it's an accessibility issue I'm facing with my tools) and I forgot about said issue with Debian.

Back on Debian now, woke up, powered on laptop, which was fully charged last night, and it's flat again.

What is it, that Debian is doing differently, that is making it go flat, when powered off?

Please note, I am doing a proper shutdown. Not just closing lid, sleep, hybernate, etc.

Any advice greatly appreciated. Thanks so much!

UPDATE: I booted into a fedora live disk, and shutdown. This time the battery did not go flat at all when shutdown, indicating that it is absolutely debian related, not BIOS or anything else.

in today's episode of "el stupido stupids around", our hero wants to look up something on a MBP 15 2015 (retina). problem is, there's already a 2010 (fatso) occupying space on the desk. is hero gonna move fatso aside to achieve said goal? 'course not, close fatso and place the retina on top. haha look at my lazy ass being expeditious!

power on the retina and... black screen. no idea what's going on as there are no status lights - thanks apple... is the battery empty, dead, wtf, no way, how can this be? bring over Magsafe 2 charger, plug in, try now... same thing. what the fuck, it's dead? maybe open it and disconnect the battery and try with magsafe only...

in a rare flash of mindfulness hero unstacks the laptops and... there we are, screen lights up, plymouth's decrypt screen is visible and all is good!

what happened is macbooks detect the screen is closed by way of magnets. so, a reed relay closes, SMC says "ok we closed, turn off screen". since there was another macbook beneath it, its magnet array got detected and retina's screen was turned off.

Do laptops with recent AMD GPUs exist? I've spent an embarrassing amount of time today looking for them and pretty much failing...

I'm looking for such a device:

• 2-in-1 laptop, or at least a laptop with a touchscreen (optimally also with a stylus)
• 14 or 15 inch screen
• Good battery life (thus probably intel CPU/GPU) and lightweight
• Optimally not a thinkpad because I don't use the trackpoint and I prefer to tap the touchpad instead of clicking physical keys.

The candidates I'm currently interested in are lenovo yoga 7i 14/15 and asus zenbook 2-in-1s, but they all use OLED displays. For these devices is OLED a problem with linux? Mostly, does linux's software-only dimming make battery life worse? And are there ways to avoid burn-in risks? (I'm using wayland compositor niri). I heard that yoga 7i has IPS versions but they are not available in my region, and I'd like to avoid international shipping. And for this reason I would prefer to stick to mainstream brands like lenovo, dell, and asus.

On this laptop I'll mainly do note taking and coding with neovim (which is dark theme and shouldn't have much problem), video playing, video editing, running small LLM and image generation models (better have good GPU multithread performance), and writing latex documents (which has light backgrounds and is my main concern with OLED). Would OLED on linux be a viable option for daily driving for my case?

If OLED is a true concern, are there relatively new LCD 2-in-1 models with good linux support and battery life?

The ATH12K driver is unstable for use with the Qualcomm FastConnect 7800 Wi-Fi 7 High Band Simultaneous (HBS) Network Adapter.

It will break it eventually and if you switch back over to Windows (ew) then you will find the Windows HBS side of you WiFi doesn't work essentially making it a WiFi-6 module and not a WiFi-7 module as the 5G signal will sill work.

I blocked the person below so i can no longer see their comment which offered no help at all and was completely useless. However, a lovely person did comment saying i think i needed the Windows 11 Version 24H2 for x64-based Systems. This information which they provided is correct. You need to update to the KB5058499 update.

Once install you must go the Settings -> Network & Internet -> Advanced network settings -> Network reset. Then click on Reset now button and it will restore the original firm back on to the module. After the restart the module should work as expected.

Edit: This is a complete revamp of the post because i was high as hell when i originally wrote it. I hope this provide more clarity on the situation and details. Have a good day <3

I have a Seagate Expansion Portable HDD, which I want to check the SMART status of^[Why? For FUN of course!]

I looked at a comment for a WD HDD, which made me look into man smartctl -> /--device after having the message from smartctl -a <dev/path> having:

Read Device Identity failed: scsi error unsupported field in scsi command

If this is a USB connected device, look at the various --device=TYPE variants

Now the manual lists many different possible device types and I am yet, unable to find the correct one. Any ideas would be appreciated.

I tried simply searching for "seagate" in man smartctl, but there was no match in the --device section.

I am currently trying to look for a way to get information on what USB to SATA adapter is being used (hopefully without having to open it up)

Some additional info:
