Update: Battery seems to be working fine. However, I have not tested it and really don't know how to test it.

Thank you for your warning post!
Do you have a recommendation for a genuine oem battery?

Rufus seems to get easier to use with every iteration. I also like Windows 11 once I disable all the connections to Microsoft account and only use a local account. BTW it takes hours for Rufus to download Windows iso file on my slow internet connection at our rural home, and I have had it time out a...

Windows 11 22H2 is out.

And Rufus 3.20 is also out:

https://github.com/pbatard/rufus/releases

I am currently using it to download an ISO of Win_11_2H22_English_x61v1.iso to a USB to install on my X230T.

It seems to get easier to use with every version.

Update: Above battery has been working fine.

I bought this on ebay:

New Genuine 67+ 45N1078 45N1079 Battery for Lenovo ThinkPad X220t X230t tablet $59.99

https://www.ebay.com/itm/325342467333

Has not arrived yet.

Found these oem Lenovo batteries on ebay:

Will do and will report back.
Thank you!

@tpfanatic et al. I have two X230T I have set the time in Windows 11 operating system on the X230T which starts with the 0271 real time clock error. It does not fix the problem. Rather, I have to [ESC] and then usually it starts booting Windows 11. But it is irritating to start it this way everytime...

Ok now I am a little grumpy with myself. When I bought the X230T I immediately upgraded it to Windows 11. But the volume up and down function does not exist when the screen is face up and folded down covering the keyboard. Wondering how I could use it in "tablet mode" with Windows 11 I came across t...

I successfully reflashed a X230T with ivyprep and then 1vyrain. Although the laptop works fine, on start up, it presents a 0271 Clock error. After restarting a couple of times by pressing ESC, the laptop starts normally. But it is annoying. I have gone into BIOS, including the Advanced tab and there...

FYI, I have followed the instructions in the below link to widen the scroll bars on three separate laptops now. Two X230T and one P53. https://www.thewindowsclub.com/windows-8-scroll-bar-hard-see-change-windows-8-scrollbar-width IMHO, especially when using a touch screen like on the X230T, it is hel...

I have two X230T (tablet). One came without a battery. One came with an oem Lenovo battery built in 2013, FRU P/N 45N1079 / ASM P/N 45N1078 and I am surprised that it provides power as long as it does for being 9 years old. Apparently, you cannot buy Lenovo batteries on their website. You must telep...

I have really become enamored by the X230T. I have the backlit keyboard version. (True, the screen is not as tall as the X61 and the keyboard feel on the X61 is somewhat better, but the X230T seems to be a worthy replacement.) So, I bought an X230T on ebay without a battery, charger or hard drive fo...

Thank you for the info. I changed from 7260 to AX210 as well, and after physically removing the BT daughter card and scanning for hardware changes in device manager, everything is working great now.

Upgraded from Windows 10 to Windows 11 Home using Rufus 3.19. Checked all THREE options in Rufus 3.19, incl bypass Ram reqmt, lbypass TPM, bypass Security Questions (although there is not a separate check box for "no Secure Boot" or bypass "unsupported CPU," and there is no "Extended Windows 11 Inst...

Rufus 3.19 is out. Should I use it? It doesn't mention secure boot or CPU type.

Thank you dr_st !!!
I watched a bunch of older, now irrelevant videos on how to install it and some more current rufus based installations and will try the rufus method.

I bought the used X230T i7 as a result of changing to a used X201T i7 because the three or four X61 which I have collected over the years have fan errors now (except for one). (I will list them for parts only along with their docks on ebay soon.) I liked the used X201T i7 allot but was disappointed ...

Bingo! RBS in for the win! Just minutes before I read your post, I used Device Manager under Bluetooth to disable both "ThinkPad Bluetooth 4.0" and "Intel(R) Wireless Bluetooth(R)" Then restarted the computer and enabled "Intel(R) Wireless Bluetooth(R)" And as you state, it works perfectly. Addition...

I ran Ivyprep and 1vyrain to replace the oem BIOS with the wifi network card whitelist. Everything went fine. I replaced the BT daughter card with a 4.0 card. I replaced the network card with a Intel AC 7260 HMW card, and now can transceive 5GHz as well as 2.4GHz wifi. But the Bluetooth is "choppy" ...

Update: Went into Device Manager and deleted Bluetooth then restarted and scanned for hardware changes and Bluetooth is working perfectly again.

Well golly gee wizz . . . upon closer inspection, the center little palm rest tab was not in its hole, causing an ever so slight upward bend in the palm rest, no doubt pushing the touch pad into the keyboard when the keyboard screw in the middle of the Memory Door was screwed in. Palm rest is now st...

The Keyboard Screw in Middle of Memory Door on the X230T Causes 8 Beeps on Startup. I am looking for obstructions but apparently pulling down the keyboard and touch pad buttons causes this problem. It seems related to this bulletin: https://support.lenovo.com/us/en/solutions/ht101771-thinkpad-x230x2...

Update: This morning I used Lenovo Vantage to update the drivers. And now the Bluetooth is acting choppy again.

Any suggestions how I can get last night's Bluetooth drivers back?

Well I stumbled my way through the process of Ivyprep and 1vyrain and everything seems to be working great. I installed the Intel AC 7260 wifi card and the newest Bluetooth Daughter card. And Bluetooth is definitely better!
