X220 Slots

Update: As of spring/summer 2019, Windows 10 will remove the drivers for the BCM92070MD / 60Y3271 Bluetooth 3.0 module that shipped by default with many Thinkpad X220 laptops. You can reinstall the drivers, but they'll be removed at the next reboot. The only solution appears to be to replace the hardware module with a 60Y3303 or 60Y3305 Bluetooth 4.0 module. I used a 60Y3303 module. It took two or three reboots but the Windows 10 drivers were detected automatically (no downloads required) and it has remained rock solid ever since. Pairing and detecting also appear to be faster and more consistent.

Suddenly, one of my RAM slots (X220) stopped working. If I insert one RAM module somtimes the Laptpo is starting and running for a short time until it power offs and reboots. Then I get Beep Notifications. Or the Notebook is not starting at all and I get Beep notifications directly. Just removing one RAM module works fine. The Flex System x220 Compute Node is the next generation cost-optimized compute node designed for less demanding workloads and low-density virtualization. The x220 is efficient and equipped with flexible configuration options and advanced management to run a broad range of workloads. What makes the X220 stand out from the crowd though is the 45mm ExpressCard slot also found here, which can be used to add all kinds of expansions and accessories, such as extra eSATA or USB 3.0. The X220 also comes with a VGA port, Display Port connection, Gigabit Ethernet and a SDHC card reader. Oh, and the engineers at Lenovo also managed to squeeze in a full size 54mm ExpressCard slot.

The Bluetooth module that came fitted to my Lenovo Thinkpad X220 was the Broadcom BCM92070MD_LENO . This is not detected by Windows 10 by default (amusingly it does appear to be detected by default by Linux distros such as Ubuntu/Mint etc.). Indeed, until I stripped down my Thinkpad, I assumed I didn't have a Bluetooth module! This module has its own dedicated hardware interface (a 'BDC socket') beneath the palm rest, and does not take up the mSATA nor PCIe half mini card slots (the PCIe socket on my Thinkpad was already occupied by the Intel N 6205 b/g/n WiFi adapter). Note that the Bluetooth antenna is printed on the module itself, it does not require a separate antenna connection. The BCM92070MD is a Bluetooth 3 module and does not seem to require any particular version of the BIOS, although it does continue to work with a modified BIOS such as the Whitelist BIOS.

Installing the following Broadcom Bluetooth drivers, strangely from the Hewlett-Packard website, allowed Windows 10 to detect Bluetooth on the BCM92070MD on my Thinkpad X220.

I recommend a reboot after installing these drivers.

Remember that you will need to:

• Ensure that the wireless hardware switch on the left side of the X220 is switched to the GREEN (on) position. For colour-blind users, note that the alternative is black (off), so you will be able to distinguish this indicator. I'm also colour-blind and had the colour checked by my daughters (females are almost - almost - impossible to be colour-blind).

• Ensure Windows 10 is not in aeroplane mode. This can be done from the action bar (Notifications sidebar) or it can be done by pressing FN-F5. You may need to press FN-F5 more than once to cycle through the various options (on other laptops, I've seen them cycle through 'all off', 'all on', 'WiFi only', 'Bluetooth only' but not necessarily in that order). If you don't have the Lenovo bloatware installed, then you may be doing this without any on-screen indication that the mode has changed.

The Bluetooth indicator at the bottom of the screen, above the PrtSc & ScrLk keys, should light up when Bluetooth is activated. I believe this light is either on or off, and doesn't change colour, but I'm not calling a daughter over again to confirm that.

If this still doesn't work, it's possible that your Thinkpad does not have a Bluetooth module at all. You should strip down and physically inspect your Thinkpad. Unplug and remove the battery, then remove the keyboard and the palm rest ('C surface') only. The WiFi and Bluetooth modules will be under the palm rest. Here's some guides:

https://www.youtube.com/watch?v=Trx6kEH_oJc - Laptop Retrospective's guide to stripping down and replacing the PCIe WiFi module; also shows more generally, how to remove the keyboard and palm rest

http://www.myfixguide.com/manual/lenovo-thinkpad-x220-disassembly/ - MyFixGuide's thorough pictorial guide to X220 disassembly covering much more than just the keyboard and palm rest ('C surface').

Here's a photo of the area underneath the palm rest from MyFixGuide, to which I've added arrows labelling the WiFi and Bluetooth modules:

If you don't have a Bluetooth module, you have two options:

• Buy a Broadcom BCM92070MD FRU 60y3271 module from eBay for eight quid or so, strip down your Thinkpad and fit it, or...

• Replace the PCIe N 6205 WiFi module with an Intel 7260 module from eBay for fifteen quid or so. This combined module is an upgrade which provides both WiFi (including WiFi C; the original only provides up to WiFi N) and Bluetooth 4 (including Bluetooth Low Energy; the original BCM92070MD only provides Bluetooth 3). However you will also need to flash your X220 BIOS to the 'Whitelist BIOS'. Note that the Whitelist BIOS allows you to do potentially stupid things that could brick your Thinkpad, There are two good video guides:

https://www.youtube.com/watch?v=jsCfFOywZs0 - Laptop Retrospective's guide to updating the BIOS to the 1.46 Whitelist BIOS (also known as the Whitelist Removed BIOS)

https://www.youtube.com/watch?v=Trx6kEH_oJc - As previously mentioned, Laptop Retrospective's guide to stripping down and replacing the PCIe WiFi module

To be honest, I found the performance of the factory-fitted Broadcom module to be a little flaky under Windows 10. My headset, which worked fine with other Windows 10 laptops and Android phones, suffered from audio drops, and when disconnected wouldn't reconnect without turning Bluetooth off and back on again ('Hullo, IT...'). It is possible that there are better Windows 10 drivers out there than the ones I linked from the HP website - do email me if you find any better.

Finally, it's well worth having a look at McDonnellTech's Thinkpad X220 Resources web page, for general X220 tips.

ThinkPad X220 Resources

The Lenovo ThinkPad X220 is an ultraportable notebook computer built on the Intel Sandy Bridge platform. Configured with a Core i3, i5 or i7 processor, 12.5-inch WXGA (1366×768) IPS or TN LED backlit display, optional integrated camera and multiple wireless options, the ThinkPad X220 provides an excellent balance of mobility, performance and connectivity.

The resources assembled here are intended to help owners get the most out of their ThinkPad X220. Please use our contact form to suggest any additions or changes.

MACOS INSTALLATION

Installation guide for macOS High Sierra 10.13 on the ThinkPad X220 is available here

IPS DISPLAY PANELS

Non-tablet models of the X220 and X230 shipped with either a standard 12.5-inch “TN” TFT display or a 12.5-inch extra bright wide-viewing “IPS” TFT display. Both varieties have a native resolution of 1366 x 768.

The IPS display is generally considered the far superior option providing a brighter image, higher contrast and much better viewing angles than the TN display. Video demonstration

Five versions of the 1366 x 768 IPS display panel are available:

  1. LP125WH2(SL)(B1) – the B1 IPS panels sometimes have issues with image retention or “ghosting” after a static image has been on the display. Some users have also reported a backlight bleeding issue with these panels.
    Manufacturer part number: 0A66673
    FRU: 04W3462, 93P5674, 93P5675
  2. LP125WH2(SL)(B2) – the B2 IPS panels are less likely to have issues with ghosting or backlight bleeding however they do not have the mounting rails on the sides needed to install properly in an X220.
  3. LP125WH2(SL)(B3) – the B3 IPS panels are less likely to have issues with ghosting or backlight bleeding and include the necessary side mounting rails for installation in the X220. (Recommended)
    Manufacturer part number: 0A66702
    FRU: 04W3919
  4. LP125WH2(SL)(T1) – the T1 IPS panels were not originally installed in the ThinkPad X220 but are completely compatible and include the necessary side mounting rails. (Recommended)
    Manufacturer part number: 0A66690
    FRU: NA
    Note: LP125WH2(SL)(T1) panels can be found in the screen assemblies of the ThinkPad Twist S230u. The process to remove the panel from the screen assembly is explained here.
  5. LP125WH2(SL)(T2) – the T2 IPS panels do not have mounting rails that align properly with the X220.

Note: When purchasing a LCD panel we recommend contacting the seller first to verify the part number of the unit they will be sending. Many merchants will advertise a particular part number but send a “compatible part” instead.

A method to repair a common malfunction with IPS panels is described here.
