ThinkPad X280: First Look

(Draft of Lenovo forum blog article)


X280 and USB-C charger

Another year, another CES, and another pre-production laptop to test and enjoy.  This year it’s a high-spec X280.  The below is not a review – more of a quick survey of specifications and a look at the usual things that I find of interest.  But first:

From time to time  Lenovo sends me a gadget. They’re handy to have around – both for my own use and when trying to help out in the Lenovo forums. I do some testing and writing as well. Beyond the use of the laptop, I’m not otherwise compensated.

Professional images are Lenovo’s.  Amateur snapshots are mine.  Opinions are exclusively mine.  I do not work for, represent, or speak for Lenovo.

 

Introduction

This X280 is the successor to the X270. I haven’t had any keyboard time with the earlier x270 but looking over its specs and documentation I’d call it a compact “conventional” laptop.  The X280 moves more into the ultrabook range (non-removable battery, proprietary small Ethernet port…).  Specifications and major differences between the ‘270 and ‘280 are called out below.

Assorted Information

The Lenovo-branded PCIe SSD is fast.  Wireless AC hooks up with my AC 1900 router at 867mbps.  SSD partitioning is as expected for a machine running a Push-Button Reset preload.  (The ADATA in Disk Management is a flash drive … I forgot to unplug…)

Virtualization

Intel VT-x was turned on by default in the test laptop’s BIOS.  In my working life I did some *nix driver development and support.  VMs were handy when coding and for occasional use of tools that weren’t available in windows (less of an issue now with Ubuntu & Bash on Windows).  This i7 16GB laptop had no problems at all running multiple VMs.

 

Linux

I don’t often run Linux as a bare-metal install these days unless I’m testing a device driver (usually on a desktop).  There are times when it’s useful to run a live distro for forensics and/or recovery  – and there are lots of folks who simply prefer Linux on their daily driver.

Testing with a live Ubuntu 16.10 and 17.04 produced mixed results.  (I’m staying away from 17.10 until the dust settles on the UEFI “corruption” problem.  There seems to be a fixed kernel now, and it doesn’t seem to be an issue for ThinkPads – but better safe than bricked.)

A serious problem was lack of UltraNav input once booted to Ubuntu.  The TrackPoint was completely unresponsive, and the touchpad would only occasionally respond.  There’s a long thread in the Lenovo Linux forum on what seems to be a similar [edit: perhaps unrelated] issue.  I’m confident that the open-source wizards will fix this eventually.  For now I did my testing with my favorite accessory: a Lenovo compact USB keyboard/TrackPoint combo. It at least allowed some continued testing and may help when trying fixes in the future.

[edit 2018.01.20]  A simple edit of the Ubuntu grub2 boot stanza gets the basics of the TrackPoint and touchpad working.  Adding “psmouse.proto=bare” (without the quotes) to the linux line in the live flash boot stanza gets the basics of the TrackPoint and touchpad working Smiley Happy  The full grub2 stanza looks like the below.  This is with Ubuntu 17.10.1:

menuentry "Try Ubuntu without installing" {
    set gfxpayload=keep
    linux    /casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed boot=casper psmouse.proto=bare quiet splash ---
    initrd    /casper/initrd.lz

I didn’t give things a very thorough workout but the basics – wifi, touchscreen, and SSD access – all seemed OK.

 

A Few Quick Tests

I haven’t had this unit long enough to do really exhaustive testing.  I did make time to try some brief basic fiddling with USB-C accessories.

An Anker USB-C to USB 3.0 hub with GigE port worked fine.  As did a CableMatters USB-C to HDMI adapter.  I was able to run 3 displays – 720p TV, laptop display, FHD monitor – independently using the adapter and the laptop’s HDMI port.

I did not have time or appropriate displays to test resolution and refresh rate options.

Battery runtime looks to be 10-12 hours in my normal use mode: ~half screen brightness, ~half way on the performance slider, a few tabs open in FireFox, maybe an text editor running.  It’s too soon to make a very accurate call on runtime.

 

The Last Word

As stated, this is more  a quick survey than a review.  I’ll edit and add as/when/if things change.  In the meantime, I’m happy to try to answer questions as time and available gadgets permit.

I’ve also received a mechanical dock that works with the X280.  It’s a “side dock” that uses the laptop’s regular USB-C, Thunderbolt, and Ethernet connectors.  A look at that interesting design will come along in the fullness of time.  There just weren’t enough hours before CES to get to the dock.  I’m looking forward to it.

For now, here’s snapshot of the X280 parked in the mechanical Side Dock:


Basic Side Dock – Ports: Audio, Slim Tip Power, Display Port, VGA, USB x4, RJ45

This wouldn’t be complete without a final comment about issues and unanswered questions:  I don’t know if the RJ45 dongle will be included with customer-ship units.  My test machine has balky TrackPoint buttons.  The fingerprint reader is inconsistent.  It also takes a minute or so to shut down.  I ascribe these to pre-production hardware and software but won’t be able to verify until customer-ship machines are available (and I don’t know yet when that will be…)  The Linux TrackPoint issue is a problem.  For now.

[edit 2018.01.08]  The above concerns have made their way to Lenovo engineering.  Hoping for feedback – time frame unknown.

[edit 2018.01.20]  A simple edit of the Ubuntu grub2 boot stanza gets the basics of the TrackPoint and touchpad working.  See above.

[edit 2018.02.26]  The laptop’s rearward USB-C port will support a -C to HDMI adapter but it is exclusive of the laptop’s HDMI port.  This also applies to the basic dock’s Displayport which apparently connects via the rearward USB-C port.

As above, the laptop will support 3 displays: laptop monitor + HDMI + HDMI via adapter, but the adapter must be plugged into the forward USB-C port.

When in the basic dock the laptop’s HDMI port or the dock’s DisplayPort may be used – but not both.

[edit 2018.05.13] It took a while but the initial concerns above have been resolved.  Long shutdown time and poor fingerprint reader function were cured by software updates.  The TrackPoint button issues were due to pre-production hardware.  A new keyboard – with updated buttons – fixed that.  The RJ45 dongle does not appear to be included in with US laptops.

[edit 2018.06.17] About docks and dongles:  The basic dock’s DisplayPort is different than the DisplayPort(s) on the Pro and Ultra docks.  All will support a direct connection to a DisplayPort monitor.  If using an adapter (DisplayPort to HDMI, for example) the basic dock requires an active adapter.  The other docks will drive an HDMI monitor via either active or passive DisplayPort adapters.
