Impressions of Lenovo’s W520

Impressions

I would like to start, by stating the obvious, this article is just my opinion and experiences with the Lenovo W520, it’s not a comprehensive, nor professional review. I’ve tried to be as accurate as possible, and present as much information as time permits.

Overall I’m quite happy with the W520 it’s performance, features, and the upgrade possibilities, the screen is wonderful, and  the keyboard is second to none, working on this machine is just bliss. It’s also a great machine for DIY like me.

Software

I ditched Windows 7 Professional, after verifying all was well. I tried three Linux distros:

  • ArchLinux
  • Fedora 15
  • Ubuntu 11.04

For installation I recommend to change the Video Card in the Bios to Integrated, and disable Optimus OS Compatibility Check. Optimus doesn’t work out of the box in Linux, there is work in progress in this front, but nothing stable yet.

I didn’t have any issues with the install process, after the install is completed you can switch to the Discrete option.  There are reports of problems using the Discrete card in Ubuntu, some users have reported hangs, while changing the screen brightness, I tried to reproduce it, and it hanged having no other option than doing a forceful shutdown, so tread carefully.

Fedora 15 has the best Power Management, you can use PowerTop to tweak PM in all three distributions, but Fedora gave me the best results, extending the battery life considerably.

With Fedora 15 battery life, during normal use for me was of approx. 6:15 hours, while with Ubuntu it was approx. 5:00 hours. The reason for this disparity is that the Fedora team has done a lot of work on PM, and it shows. I could have gotten even better results, had I disabled Bluetooth and put the Wireless card in PM saving mode. I didn’t run this test with Archlinux, because of time constraints.

On the Thermal side of things, it runs quite cool, It’s super quiet, CPU Scaling works out of the box, and it’s very efficient.

Not tested Yet

USB 3.0: don’t have usb 3.0 devices, but 2.0 works fine in this ports, with the exception of the Ipod Touch, which charges but it’s not mounted.

eSata: Ordered an external drive, will report when it arrives.

mSata: It’s my understanding that you can set a mSata drive as the main disk, and your internal drive a secondary. I will try this once I get my hands on a mSata drive.

Raid: Raid is not supported on my machine, it seems they use a different chipset for the machines with Raid capability, so if that’s important for you then you should order with the Raid option enabled. However you can still install a secondary drive on the DVD bay (with the optional cage) and it’s recognized.

WWLAN: There are reports on the web, that it works well, but I haven’t tested.

Express Card: Don’t own one.

Important Note on Bios Upgrade

I upgraded my bios from the default v.1.0.6 to the latest v.1.0.25 (which is really v.1.0.24) and it caused a few issues with ACPI in Linux, mainly none of the distros I tried with Kernel 2.6.38 or 2.6.39 could handle this changes. I didn’t try with the latest Vanilla Kernel. The upgraded Bios caused no issues in Win 7 Pro.

The issue is not present on prior Bios releases, so I’m using 1.0.22 which works fine on all the tested distros.

    Thanks for your write-up on this notebook, as I’m having some issues with mine and it looks like I’m running on BIOS 1.24/25. Can you detail what issues you had with this particular BIOS that made you downgrade to 1.22?

    I just unboxed my W520 and am strongly leaning toward Ubuntu. Have you had any issues with external monitors (either VGA or DisplayPort.)? How about the trackpoint (I think that’s what they call the red joystick mousey thing)? Also just out of curiosity does the biometric login (ie fingerprint) work?

    Thanks for the informative post.

  3. @Nelson The issues I had with Bios 1.24 were ACPI related, couldn’t get info on ACPI status, so no battery status, hibernation, or suspend, Speed step was not working either. This is with a default install of Ubuntu 11.04.

    @Joseph I haven’t had any issues with external displays, so far I’ve only tried VGA. The trackpoint works out of the box, as well as the mousepad. The fingerprint reader works, though the setup is a bit hairy in Ubuntu, I simply gave up.

    Fedora 15 supports the fingerprint, and it’s easy to setup and works quite well with GDM, and all authentication related applications.

    One issue I had with the default Ubuntu 11.04 were random freezes, after a bit of tracking down, it was a bug in the Intel kernel driver, I upgraded my kernel to 2.6.38-10 and it hasn’t frozen again.

    Hope this helps.
