@george Is there a 10 or 11in touchscreen that would work with the CM5 core board and V20 Carrier Board?

@george how could you explain how I could connect the Quectel RM500Q-GL 5G modem? I finally got around to purchasing the components for my tablet build and just received them. The Wifi module already occupies the A/E key M.2 slot, and I'm hoping to add an SSD to the other SSD M.2 slot. Are there enough lanes available on the M.2 slot to split for an SSD and the 5G modem?

@george is it possible to connect all the following to the main simutaneously somehow?

• NVMe SSD
• Wifi
• Quectel RM500Q-GL 5G modem

Re: Explore unlimited possibilities - Coolpi 8-inch touchscreen

I would like to build a tablet using the Cm5 core board and v2 carrier board used in the CM5 laptop. I have the 14in CM5 laptop and am very pleased with its stablity as a daily-driver. Shrinking it down to an 8 or 10in tablet form-factor would be ideal. I've got the touchscreen and boards in my cart on Aliexpress and am ready to pull the trigger pending any feedback on the following potential concerns:

1. Heat management (low profile heatsink/fan like the laptop?)
2. Structural rigidity (PLA 3D print case?)
3. Hardware buttons (power, volume, brightness, etc)
4. 5G Cellular Modem possibilty

Any insights/thoughts would be greatly appreciated.

@george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

@george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

@george I purchased to V20 upgrade and installed it with Ubuntu 24.04. It does not recognize the NVMe stick. Am I doing something wrong?

@george would you mind taking a look at this issue. I have not been able to find the instructions specific to the V20 board upgrade, so I may have missed something. I've pulled the notebook apart again and reseated the NVMe stick. I installed Ubuntu 24.04, but maybe I should have used 22.04?

I received the V20 mainboard and installed it. I followed these instructions including pulling, compiling and installing the latest kernel source, and the system boots fine, however it does not recognize the NVMe card.

@Rebel-Rider Thank you. Just odered.

@george my bad for not being clearer. I have the original notebook, and I recall you pointing us to Aliexpress to purchase a replacement main board that would provide usb-c charging and a few other new features. I was hoping to purchase the newer version of the mainboard but I cannot find it available anywhere.

Re: Cool Pi ARM Notebook Preview

Not able to find the main board upgrade for my original cm5 notebook. Any idea if they'll be available again soon? Or if there's another upgrade pathway?

@george How would I go about upgrading to a touchscreen? Can I purchase the parts somewhere and replace them myself?

@jack_admin @enok71 Great thoughts. What comes to mind the is the Framework (https://frame.work) concept. A modular design that allows folks to mix-and-match components. This already somewhat achievable as long as you are somewhat handy with a 3d printer and a soldering iron, and @george has been very amenable to helping folks through the pitfalls of adapting one-off solutions. Some possibly minor changes to the core design might open this laptop to a wider market, especially in the EU & US, for those, like me, who are not quite as handy with a soldering iron as they think they are - allowing for both "maker" level adaptations and consumer-grade mix-n-match.

I've had this linux laptop for a while, and it has turned into my daily driver in addition to being invaluable for edge-device development on-the-go.

I'd be interested in any thoughts on adapting it into a 2-in-1 platform, similar to my aging Dell Latitude 7390 2-in-1 it's replaced. Some minimum adaptations:

1. Change current screen to touch screen
2. Replace shell or hinge to allow for full 360 rotation into tablet mode
3. Upgrade to Motherboard to allow for an additional M.2 port for internal 5G Modem.

If there are any others as intrigued by the potential of this device as I am, I would be interested in sharing the development cost of such a unit, if there is a capable maker willing to take it on, and as long as as at the end of the day the total cost to me does not break my bank, incurr the wrath of my wife, and results in a functional unit at a marketable cost.

Has anyone had amy luck installing the Windows 11 arm64 insider preview on the CM5 laptop in an LXD Container? Note, I'm NOT interested in installing Win11 as the host OS, rather as a LXC client.

As some background, I am also hoping to do the same on an Ampere Altra arm64 server, but I'd like to be able to access Win11 functionality on the laptop while on the road if and when I might need it, instead of carrying another amd64 Win11 laptop.

• When I plug a desktop monitor in, the edid.bin file is empty and the monitor continues to act as if it has not been plugged in.
• So I plugged the portable monitor in, and the edid.bin remained empty, even though the monitor woke up and displayed the desktop.
• Below is the dmesg output from the time I plugged the portable monitor in (I imagine the same i2c read error would be happening with the desktop monitor):

@george Please help me out here. The HDMI port only seems to drive small portable monitors. It does not recognize the Dell P27815Q 27inch monitors or the Samsung 50inch TV when I plug them in. This makes the laptop virtually useless to me if I cannot use it to drive HDMI monitors while traveling in meeting rooms. If I cannot get this resolved, I will need to return it and get my money back.

Just wanted to set the record straight regarding the Cool-Pi team's responsiveness. @george had immediately answered me in another thread (Laptop USB-C Alt Mode). My bad for creating multiple threads on the same topic and not checking them all.

My apologies @george , I kept looking in the CM5 Laptop thread and not here for an answer, when you had already answered here, immediately. I will check this out today.
