The X230 is the fourth model in the X2xx series and was manufactured from June 2012 to August 2014. It is the successor to the successful X220.
The biggest difference compared to previous X2xx models is the new ThinkPad Precision Keyboard, which is now installed in all ThinkPads.
The X230 was also produces in the following variants:
It is standard practice to update to the latest Lenovo EC firmware before replacing the stock BIOS on Thinkpads. However, as a result of CVE-2019-6171, newer Lenovo firmware update files have been digitally signed. Please note that if you upgrade to a locked version, you will not be able to patch your EC without downgrading it. This is not the desired outcome, as it will prevent you from making changes to the EC firmware, for example with the thinkpad-ec tool. Recommendation is to flash the last modifieable EC firmware version.
The last modifiable version on the X230 is BIOS 2.75 (G2ETB5WW) EC 1.14 (G2HT35WW) (download).
The versions available from the factory and the maximum possible expansion stages are listed.
All CPUs support vt-x, not all support vt-d (PCIe passthrough via the help of IOMMU).
Upgradeability: It is not (easily) possible to replace the CPU as it is soldered to the mainboard.
Although the Intel HD 4000 graphics is capable of driving 3 screens simultaneously, this is not intended for these Thinkpad models. Therefore, only two screens can be used at the same time, either two external monitors or one external monitor and the internal display. Of course, this restriction also applies to operation in a docking station/Ultrabase.
2.5“ SATA II hard drive or SSD with a height oft 7mm height can be installed. The installation of hard disks & SSDs with 9.5mm height should also be possible if the caddy is removed.
An SSD with mSATA connection can also be installed in the WWAN slot (mini PCIe slot left of the WLAN slot).
It is only possible to install a half-height only adapter as the necessary brackets for a full-height adapter are missing.
It is not possible to WLAN adapters due to missing PCIe lanes.
To our knowledge, the following docking station options exist for the Thinkpad X230 (sold at Vikings as bold text).
All Lenovo docking stations for the X230 come with 1x VGA, 1x Ethernet (RJ-45) and 1x Kensington Lock.
It has been reported 2) 3) 4) that the two USB 3.0 ports on the left appear to suffer from read and write errors when USB to SATA adapters are being used on any supported coreboot version with a SeaBIOS payload.
USB 3.0 sticks work fine and the USB 2.0 port on the right does not have this problem.
This may be isolated to the SeaBIOS payload.
This is being investigated (with low priority, don't expect an update soon); we'll update this article once we know more.
