Well I came across someone who has one and I was able to fiddle with it a bit. I dont know every detail about the device, but I answered my previous questions. So if you want to buy one....

Q: Does the device function when there is no internal battery(like a normal laptop)?
A: Yes. Though a caveat. The machine requires the user to boot into the BIOS and change the date and time, every time the device is turned on. As it seems to rely on the internal battery to maintain the BIOS settings. Every default setting seems fine unless you want the gpu to use more RAM; default is 3GB. Some people prefer 4-6 or an Auto setting.

Q: Can a user install Windows 10?
A: Yes. I tried a few versions. You can go back as far as 21H2 and onward up. I lack images of anything earlier. Sorry.

Q: Will the Lenovo Win11 manual install drivers function, even though Lenovo explicitly states only Win11?
A: Yes. Why? How the hell should I know! But some nice programmer made it possible, so lets not rock the boat!

-------Added information, to save your sanity------
Missing Driver; USB4
https://support.lenovo.com/us/en/downloads/ds564847-amd-usb4-driver-for-windows-11-version-21h2-or-later-10-64-bit-version-21h2-or-later-thinkpad

This is the missing driver you will need. If you right click The PC and on the right side, click Device Manager(other methods to get there). You will see you are missing 2 drivers. The lenovo link, is the exact file you need for Windows 10. If you need it for Win11, look up the same thing and choose win11.

If anyone ever needs to know wtf a mystery driver is. Right click the entry in Device Manager and go to Details. Click the drop down menu(looks like it says Device Description; its a menu list) then choose Hardware Ids. The id is what you should look for in different search engines. This will help find the driver you need.

Q: What about Legion Space?
A: Yes. It seems to also work just fine, though the software seems to sit in the taskbar as a program or folder instead of running in the background or in the icon area as a background icon. Ok so Im crap at explaining it. But most understand what a program looks like on the standard taskbar area. No idea how or if it can be iconed near the clock.

----------added more info---------

Q: Does the device have Battery Bypass?
A: Yes, it appears to have this. However, it uses Legion Space to toggle a switch in the User Interface of Legion Space to do it. It has one option. To set the charging stop at 80%. While it is better than nothing, I would hope a 60% option comes with future updates. For context; The pc was shut off completely, without sleep or hybernation. Pack in 65w charger was used. Charge at time was 18% and charged all the way to 80%, while turned off. No apparently button to visually know where the charge state is. However, there is a trick to know when the device is actually finished charging. Phyisically touching the wall charger; if hot= charging device. If cool= finished charging.

After pc is done charging to 80%, pc was turned on. Appears to stay at 80% battery while plugged into AC.

Some annoyances though:
1- Right analog stick does NOT seem to have a mouse optional mode. This is just stupid. Literally one of the most obvious things anyone trying to do is to fiddle with the right stick, to use as a mouse. Left/Right Shoulder buttons should be left/right mouse buttons. But not anyway I can find to the how. The only mouse options seem to be a track pad the size of a postage stamp and an option to detach the right controller to then flip a physical switch to make it a joystick mouse....on a table. All this crap instead of the most obvious....the analog stick idea, wtf!?

2- With the machine shut down and not in any sleep mode. The option to plug in and charge the internal battery is a good idea. It has an option in the BIOS to show the percentage of battery charge when AC power is plugged into the device. Why is this annoying? While it flashes the percent onto the screen when plugged in from AC, it does not seem to respond with any button press to show the user where the charge is after the first plugin shows it. Then turns off the screen a few seconds later. I pressed all the buttons. Nothing seems to tell you what percent the charge is at. I also think when pulling out the AC cable and immediately plugging it back in, presents a electrical hazard. The very least, it is a bad idea. Only other option is to turn on the device and check within the OS. Which defeats the purpose of the tablet/phone-esque feature.

3- Speaking of which...While in Windows, lower right corner has a little tv icon. Click this and right click the "Tablet mode" options/settings. Choose the turn off permanently option(save your sanity). This really pissed me off, being on by default. I truly hate tablet mode. Whomever made this in the OS, I hope a stench of a 1000 flatulent camels blow in your general direction! May you stub both toes and fall into a thorn bush!! >_<

Anyway. Just sharing the knowledge, as Win10 is a lot more compatible with certain games and software than Win11.

Have a nice day(except the clown that made Tablet Mode in Win10.... give me back the hour of my life you......not not nice person!!).

edit: Additional information about the battery.

Another edit:
It seems the software developers goofed pretty bad. After about two weeks of testing the device. The operating system would get so corrupted, that it dumps the entire os into a trial period mode. But it gets worse. Not only does the system do this, it half does it in a manner that does not explicity let the user know right away. So you get totally fu!*ed, due to your return window lapsing. Meaning you cannot return the piece of crap for a refund.

So what may cause the corruption? Well it can be a combination of small details that lead up to this. But since I was only observing the device and not the shmuck that designed it. I can only speculate.

I can however tell you what I observed. Lets begin there:
In the BIOS, there are a few things. TPM, BIOS self heal and secure boot. Normally these are to protect the machine, so a bad actor getting your rig, cannot tamper with it. The problem is, if you are bad at your job as the developers of the device seem to be, they goof the software. Thus making the os get corrupted....and your lose everything on the drive.

I wanted to test a few different operating systems. So I tested the device in various states. Different combinations of settings in the bios. Several times when restarting the pc, I was greeted with the bios self heal screen. This was not well recorded, beyond me and my surprise. I truly did nothing out of the ordinary of using a few different versions of linux on USB. So the machine having a reaction is a mystery as to why(crappy dev work from lenovo?).

Oddly enough, within Windows is where I detached an attached the controllers a few times, did I notice I could not properly eject usb memory devices, via the taskbar icon in the lower right(near the clock). Then I looked at the activation area in the Settings. It was blank. I ran a few powershell commands to check the os key. Errors and no key access. Ran some basic DISM repair commands and that supposedly fixed a few corrupted or broken things. But it really did not. From that point on, the os behaved as though it were stuck. Halfway in trial period mode and activated. It didnt explicitly show trial period function, as though it were still activated. But many os features failed to function at all or were broken in odd ways.

So in short. If you buy one, be aware, that even using the device in a normal manner, can cripple it. Detaching the....detach able controllers after swapping the os can cripple the device. FYI- factory untouched bios.

99% certain there was a problem in the way the BIOS is programmed. As the bios has been an ongoing problem users, since lenovo began selling these machines.

PS- if this happens, it requires a full wipe and clean install of the entire os. After 2 weeks. That is not acceptable!!

You are warned about this device.

Anyone familiar with github mind helping me find something?
https://github.com/Valkirie/HandheldCompanion

Trying to figure out if this software can be used offline. Because according to different random redditors, this has analog stick mouse function.

The "just install" nonsense is not the entire package as the dev implies. Which is really deception being a troll.

Releases -> Assets -> Download and be happy

Thanks, but thats an online installer only. Im guessing the dev didnt care to make an all in one offline package :/

edit:
Best I can find as a work around is Gopher360+RBTray= add to startup.
It sucks, but it sort of works on desktop. Gopher, closes in when it detects a program. Even Task Manager. So it helps, but sucks when you need it in a program.

If you go back enough to the 0.15.1.1 version, it has a offline installer.

Didnt know that, thanks. But then again, I have no idea how to update it offline to latest. Any ideas?

Added some battery observations.

Also, if you do use Gopher for stick to mouse. You should add a shortcut of it to your desktop. Toggle it to run as admin in the properties, in order to have it run while most programs are running, to use it.
When you want to play a game, unhide it it using the right controllers Y button. Then click the programs x to shut it off.
If you forget while in a game. The program will conflict with everything you touch.

After you quit the game, just click the desktop shortcut again and Y to hide it.

If you have made your Legion Space settings arranged the way you are happy with. There is a trick to unf**k the game store garbage from being so obnoxious and bothersome. Rename the LegionSpace.exe to something else. The accidental button press on the left controller, no longer turns it on. But the right side panel stays active as does the right side button. So the settings from the left side remain on, but the crappy part of LS that everyone hates, remains off. Even better, it doesnt even auto start!

It may not do this if you use the AMD graphics driver though. Seems it works better with stock Lenovo graphics driver.

Yeah, I agree. Kinda sucks too. Because I hate discord. People ban you for asking legitimate questions and the moderators tend to side with whatever a moderator says. No matter how crazy the moderator behaved.

Plus I hate signing up for yet another thing to keep track of. Ill take IRC any day.

Added a link for a specific missing driver you folks will need. Lenovo does not natively ship Win10 for the Legion Go. Thus that is why that driver was missing. So I added the link for it. Hope this helps someone.

Legion Go Dock:

Sometimes I wonder how so many "smart" people, can be so dumb. The Go device has USB-4 ports; 1 top/1 bottom.
The dock blocks the bottom and runs a cable to the top......

Like owning a 5million usd home and having an out house as the only toilet, in the back yard -_-

So if you buy the pc. Dont buy the dock. At least not the official one.

Perhaps a silly question to ask everyone, as Im the only one it seems to know much about this thing on forum. Ill ask anyway, does anyone happen to know the positive and negative wires the Legion Go has for both speakers?

A few inspections show a 4 pin connector with wires of green/blue and brown/black.

I was thinking about a modification. Removing the speakers as they are trash anyway and add in 2, 25mm fans at 5v and 2pins.

But how would this work? The 3.5mm port or a usb audio option.

But wait! The speakers get power shut off when the pc detects a 3.5mm connection, thus switching over to that! Gadzooks!!

Going into windows and or linux sound settings and forcing both to use the same channels, will not in fact shut off the primary speaker system. Thus continuation of electrical power being supplied to the speaker connection. As in, you still have sound via usb or 3.5mm jack at the same time as the removed speakers. So the fans run quietly and provide 2 extra areas of cooling. Which if you look inside the device, it has ample room for a 25mm blower fan.

......now if I knew which wires were which......crap........ >_>

Anyone knowing this info would help a lot.


edit for typos

Are the speakers actually powered? I'd expect them to be just passives with 2 wires each as usual, and the amp is on the MoBo somewhere, so there's no 5V or other power source on these four pins, just two audio signals with possibly not even a common ground, if it's a differential signal.

....crap....You just reminded me of exactly that. I havent dealt with speakers in some years and forgot. Well....there goes 20 bucks. Maybe I can dremel out a usb A slot and add a fan like that. Full jank mode lol

I should have spotted the wiring as being passive, but I wanted the fans. Guess it slipped my mind. Thanks for the help.

If you're opening the thing, then you could just use emanelled wire, or, even better, wire wrap wire, to make a connection from the USB power to the fans, all inside the case, and not even need to mess with audio source settings and such.
