I noticed a tiny component near the power input connector was loose. Looks like a LED? Could it have dis-soldered due to some sort of overheat?

My CM5 laptop power input suddenly stopped working. The power adapter is working, I tried another adapter, didn't help. The laptop still booted and worked normally until the battery became exhausted.
What could have happened? Is there some sort of fuse on the board?
Is there component layout and/or schematic for the laptop carrier board public available? Thanks.

@george Thank you!

@george Yes I was considering the possibility to base a custom board on a CM5 module, for a project.

I tried to google for a CM5 module reseller but couldn't find one. Where can I buy it? Thanks.

@george Thanks that solved my problem.

I followed the kernel update instructions (git clone, compile, copy, reboot) and now I have no network interfaces and no bluetooth. I don't have time to dig into it right now, just wanted to warn that something may be missing in the instruction.

@enok71 Just in case someone reads my postings in this thread: The best source for coolpi hardware support packages is probably Georges ppa. Probably best to avoid mixed in packages from Liu Jianfengs ppa.

@jack_admin I believe there can be different variants with different price tags. The top model could be e.g. at least double your current price. If the features appeal to technology aware consumers in west I think they have no problem paying for it.

Imagine a 1440p camera showing showing crystal clear streaming video in "Teams", with the hardware accelerated video drivers doing their job so that the fan remains quiet. That would be a laptop to pay for. Colleagues would ask "what laptop is that??". It would advertise itself.

A high quality keyboard is also a very important fundamental requirement for buyers with budget. I personally think backlight should be mandatory. And international keyboard laptops are impossible to sell in Scandinavia.

The security related features I mentioned (fingerprint reader, security chip, NFC reader) are more "nice to have" things, but would give the laptop a security edge, and everyone ask for (and will pay for) improved IT security these days. Make sure "secure boot" is implemented and working if going that path. Linux and open source software is preferred before Windows for security aware users and you already have that.

These are my thoughts. Of course I know very little about e.g. Chinese customer needs or wishes.

@anernest I also apreciate this laptop, although I have no need at all for touch screen, 5G modem or tablet mode. Would be more interested in

• Better camera
• USB-charger compatibility
• Keyboard backlight
• Scandinavian keyboard layout option
• Fingerprint reader (looks like there is already an input for this on the current board)
• And why not a TPM or security chip option?
• Perhaps an NFC reader option?
