Lenovo has announced a new version of the the W series mobile workstation, the ThinkPad W520 which comes with a wide array of features designed to meet the demands of high need business users who don’t want to sacrifice power while on the road. The W520 notebook announcement is part of the ThinkPad 2011 refresh including the T and L Series.

ThinkPad W520 Quick Specs:

Detailed specifications - ThinkPad W520.

As a mobile workstation the W520 is able to be configured with high end options. Notably the ThinkPad W520 can be configured with the Intel Core i7-2920XM 2.5GHz Second Gen Intel Core i processor, up to 32GB RAM, up to a 500GB 7200RPM hard drive or 160GB SSD. The Graphics options include up to the NVIDIA QUADRO 2000M 2GB VRAM GPU. There are numerous options for WiMax, WiFi and cellular connectivity.

Other enhancements include fast booting options with Lenovo RapidDrive and the ability to run on TurboBoost longer thanks to TurboBoost+ which allows Lenovo notebooks to stay in TurboBoost mode for extended periods.

ThinkPad W520 Features:

On top of the newest options, the ThinkPad W520 comes with numerous features that set it apart including an optional industry first integrated color calibrator. The W520 is also Milspec tested for ruggedness, allowing for use in a harsher environment.

Other new enhancements include the ability to dial in voice chat to either one user or to listen to all users in conference mode, and the W520 also comes with keyboard noise suppression so that you can take notes while on a video chat.

The W520 can be closed up for the walk form one room to another without losing the WiFi connection and IT admins will appreciate the interoperability between W, T and L series ThinkPads.

ThinkPad W520 Battery Life:

The ThinkPad W520 battery life varies with configurations, but with the standard 9-cell battery the life can range from 8.9 hours up to 10.7 hours. The W520 can make use of the T Series Slice Battery to extend the battery life greatly.

Lenovo ThinkPad W520 Pricing and Availability:

The Lenovo ThinkPad W520 will be available on March 29th with a starting price of $1,329 along with the rest of the ThinkPad T, ThinkPad L and ThinkPad W lines.

Specification

The W520 comes in 4 quad-core configurations, and 1 dual-core configuration. The quad-core configurations support RAM up to 32GB.

It is similar to the T520 model but supports more powerful CPU's and GPU's and has 4 RAM slots (32GB total).Compared to the superseding W530 model it notably features the conventional keyboard, an eSATA port, and full-size DisplayPort connector.

It is noteworthy that the graphics output (VGA and DisplayPort) are connected to the NVIDIA GPU, so this GPU needs to be controlled in order to have video output.

For more detailed specifications, please refer to the ThinkWiki

Status

The W520 is implemented as a variant of the Board:lenovo/t520 and so it shares much of the same status.

Patch history

In November 2016 Charlotte Plusplus has made an initial attempt (mailinglist posts) based on the T520 firmware, with added romstage additions for ram init. This patch was committed in full to the mailing list, but not as a diff to the Gerrit infrastructure.In February 2018 Nico Rikken again customized the T520 firmware, and delivered a working patch set.

Proprietary components status

• CPU Microcode (optional)
• VGA Option ROM (optional): the native graphics initialization tested gave video artifacts in SeaBIOS. When using VGA Bios there were none.
• ME(Management Engine) => you do not have to touch it (just leave it where it is). Also the stripped down T420 version can be re-used.
• EC(Embedded Controller) => you do not have to touch it (just leave it where it is)

Known issues

• The 2 USB 3.0 slots on the side are not working for boot media, just the USB 2.0 slot on the back.
• SD cards mount as read-only in Ubuntu 18.04 (unconfirmed report by Nico)

Issues reported by Charlotte Plusplus

In 2016 some issues were reported. These need to be verified base on the most recent W520 patch.

• Native VGA init is not working reliably (discussion thread).
• The coreboot configuration consumes more power than the vendor BIOS does, so some additional settings might be required. (discussion thread).
• No ACPI event when (dis)connecting the bay.

Works

• CPU (4 cores, 8 threads)
• Suspend and resume
• Ethernet port (GbE blob was put into place)
• Speakers
• Webcam (which is an internal USB-device)
• 4 RAM-slots
• Booting GNU Linux from USB using SeaBios
• Speakers
• PCIe Wifi
• Fan
• Touchpad, trackpoint and keyboard
• Ethernet
• Keyboard ACPI events
• VGA and DisplayPort output using the patches below
• Bluetooth

Building

Just run make nconfig, and select the board Lenovo W520. Other configurations include:

• Size of CBFS can be set up to 2M (0x200000), perhaps larger like the Board:lenovo/t420 but this might depend on the chip.
• You can select 'Use CMOS for configuration values'.
• You can use native graphics initialization.

To obtain ME, Intel Descriptor, GbE images you will need to read the BIOS off your T420.

To use VGA option ROMs, you can manually add it to CBFS using cbfstool multiple times to support more GPUs on a single board.

Perhaps adding 1 rom for NVIDIA and using a link file might work as well.

VGA / DisplayPort output

At the moment of writing two additional patches are required to enable VGA/DisplayPort output. Then output works out of the box with Ubuntu 18.04 (Nouveau driver)

• _ROM ACPI call enabling Nouveau to load the optionrom patch
• 'Dual Graphics' CMOS option to enable the GPU patch

Then Dual Graphics mode can be activated using nvram:

Flashing

The location of the chip is similar to the T520:

When flashing with a Raspberry Pi no external power is needed. The 3V source from the GPIO is sufficient. The pins WP and HOLD can be left floating.
