Does the device have a CMOS/BIOS battery?

If not, does the clock and settings have a solid state, whereby the primary battery is unplugged; the settings and clock/date remain?

For context, I always like to unplug a battery and run from wall power. It may have battery bypass, but I still need to know if the device will run while the battery is not present. Always nice to know if you can still use it when the battery dies forever.

If you actually own the device and detach the battery. I would be very grateful for the test.

Side question

Some people say they installed Windows 10 on their Legion Go. They claim on reddit the Windows11 drivers from Lenovo are compatible. Has any of you owners tried this? Really curious.

I can't answer all of your questions, but I can answer some of them.

This does has a battery bypass, and you can set it to limit charging the battery at 80%. At that point, it will completely run off of AC power. As strange as this sounds, I have only been able to get that to work by making the change through the Legion GO app in Windows 11, but it is absolutely done at the bios level since I primarily run Linux. I have yet to find a BIOS option for setting a charge limit. The BIOS does have an option for temporarily disabling the battery, but my understanding of this is that it is for troubleshooting only. It implies that the battery is not required but I have not disconnected anything to verify.

I do not know how well it runs Windows 10, but I can say that it runs Linux well. Bazzite works beautifully (but it's too steam-like for my preference), and Ubuntu also works out of the box. I was not able to get the built-in controllers to work with ZorinOS, but otherwise it worked fine there, too.

If I may ask. Would you be willing to remove the back plate to unplug the battery?

2 reasons.

1- To verify AC power works while a game is running(no sudden shutdown).

2- Look at the date and time and see if the device keeps the last known information. As in, it keeps BIOS/UEFI settings + date and time. I dont expect it to be exact time. Just not reset.

It would help save the expense. Maybe someone can verify Win10 later

Thanks for the info you have provided already.

Well, I took the screws out, but after checking some videos online after it wouldn't open, it looks like I'm going to need to get some pry picks. I don't think I have anything on hand at the moment to get this open without risking some damage (my hands are about as useful as clubs). All my other laptops in the past have opened by just removing the screws, but I've been meaning to get something for this kind of job. If I can somehow get around to getting this open in the coming days, I'll make sure to post back here and let you know what I find.

As far as my overall experience with the device - it has been incredibly positive. The screen is nice, it runs well and has a good build quality. The negatives are that the controller can get uncomfortable due to the lack of an ergonomic curve, and it really could use more than 16GB of RAM (both of these should be remedied with the just announced second version). My GPD Win MAX 2 outperformed it and that is likely due to the 64GB of RAM that it had (but it bit the dust twice, so it's now a goner). The fact that Linux and Heroic works so well on it is a huge plus for me.

Anyway, sorry I failed at getting it open. I'll let you know if that changes in the future.

I wouldnt advise doing so as Im going to say how I do it; I normally use a a sharp butter knife lol

But only because I dont care about the paint. Normally when I do care, a guitar pick works. Plastic. Ive used razor blades. But only to shim a wooden tooth pick in the gap. Then if the tooth pick broke, I know I applied to much force. So I double up and shim 2 toothpicks and gently move along the edges.

Janky. I know.

But thanks for looking into it. A main concern is I bought a OneNext mix...wtf ever its called, similar to gpd. Bought a gpd too. Then I realised they both cut so many corners, that if you unplug their batteries. You now have a paper weight. So pray the battery on your gpd never bloats like mine had. Both machines broke in months. Neither would be able to run off wall power and both lack a cmos battery, while also lacking a solid state BIOS that saves the settings without power.

Pure genius.....seriously. 75cents for a cmos battery and a standard in laptops from the beginning of time and none added.

Oh im not salty about you. I dislike those other non lenovo companies for making crap machines. Not a fan of lenovo, im hoping they may be different.

Hoping anyone else has the information they can verify.

edit= typo

If anyone else has a Lenovo Legion Go device and would be willing to perform a few basic easy tests. This is the short list of what information I am looking for:

1- Remove the back plate and unplug the battery. Youtube has a few "teardown" videos for the legion go. Reason? To verify AC power works while a game is running(no sudden shutdown). Obviously perform the test of AC while the battery is unplugged. So, unplug battery while the device is off. Plug in AC power. Power on. If all looks ok, run a any game for at least 2 full minutes. Good enough.

2- While the battery is unplugged. Look at the date and time and see if the device keeps the last known information. As in, it keeps BIOS/UEFI settings + date and time. I dont expect it to be exact time. Just not reset.

How to safely access your bios:


Shut down your Legion Go in Windows.
Hold down the Volume Up button.
Press the power button (don't hold).
BIOS
Configuration; Look at the date and time to see if it was roughly when you unplugged the battery or if it is reset completely.
Tap "Exit".


3- If you have an interest in your device running Windows more efficiently, using less RAM. Install Windows 10 and grab the manual device drivers and Legion Space from Lenovo directly. They say Win11, but I am seeing multiple people on the web show Win10 being functional with Win11 drivers AND Legion Space. I would like to know if anyone here can confirm this(with your owned device...duh!).

Im not asking 1 person to do all the tests. Any is fine. However, keep in mind, performing these tests yourself, will benefit you as well. Knowing your device wont turn into a paper weight when the battery dies, is piece of mind. Plus it can be repurposed as a desktop machine or used with an external battery when all compatible internal battery options are no longer available.

Gotta admire the chuzpe.

If yer going to snipe, atleast explain your comment.

Asking for information that benefits both the owner of the device and everyone else that buys one, is a positive. Most people are not thinking about long term device functionale. But it is good to do so.

Aside from that, thanks for the bump.

Thinking about it, the main interest is, whether or not it runs normally from AC with the battery unplugged.

Conflicting information, even on the main LeGo forums and reddit threads.

Just bumping incase some one may confirm AC power capable.

Thank you. Passive curiousity. Have you tried the Deck after detaching the battery and running off AC power?

I have not.
