Using handheld computer as a main workstation

In this post I would like to share with you some detail about using GPD MicroPC as a main workstation.

Using MicroPC as a portable workstation

Monitor – Lenovo ThinkVision M14
Keyboard – ThinkPad Wired USB Keyboard with TrackPoint

The keyboard is OK. It’s quite light (398 grams) The build quality of the keyboard is decent. The layout is obviously much worse than the layout of the famous 7-row ThinkPad keyboard (AKA UltraNav). But these USB keyboards are no longer produced. The chinese copies of these keyboard available today are awful (read the user reviews on Amazon).

The monitor is very light for 14 inch screen (624 grams) and durable. The build quality is fine. I was quite surprised that 14 inch screen can be powered by such small device as GPD MicroPC. The only issue I have with this display is that sometimes it spontaneously turns off for a second or two. It does not bother me too much, because it happens 1-2 times per hour. But evetually I would like to resolve this issue somehow.

Using MicroPC as a home workstation

Monitor – Dell U2713HM

In general, MicroPC does the job pretty well. However, there are two notes I would like to mention.

  1. This monitor does not support the native resolution (2560×1440) via HDMI port. In order to connect MicroPC to this monitor I had to use StarTech HDMI to DisplayPort Adapter. This’s an active digital video converter, which requires external power (via USB port). All passive HDMI to DisplayPort cables do not support resolution higner that 1920×1080.

  2. It’s not very convenient to attach 5 cables in order to "dock" the MicroPC. I would really to have a dedicated docking port on MicroPC (like the docking port on ThinkPad laptops).

UPDATE from 2019 Sep 30: The second issue was fixed according to the anonymoushindeiru‘s suggestion. The USB Type-C Hub does the job pretty well. I’m using Satechi ST-TCMAM. See the last photo in the gallery.

Happy Hacking

I have recently attended a talk by Richard Stallman and used the opportunity to sign my Ben Nanonote. It’s a clamshell handheld with free hardware designs. It runs free software (OpenWrt operating system).

Upgrading SSD in GPD MicroPC

SSD in GPD MicroPC is replaceable. So MicroPC owners can replace the default SSD (Biwin G6327) with a higher capacity SSD or with something more reliable. I decided to upgrade to Transcend 400S.

The upgrade is quite easy to perform: remove 5 screws from the back of the device, unclip the bottom panel and you are ready to replace the SSD.
Here is a detailed instruction in case you need it.

Transcend 400S is a bit faster than the default SSD, you can see the benchmark screenshots below. The temperature of Transcend 400S is usually around 40 °C when the fan is enabled and 45 °C when the fan is disabled.

If you would decide to use the official Windows 10 recovery firmware from GPD (GPD Micro PC WINDOWS 10 Pro Factory 20190320.rar), please note, that there is an error in this archive. MicroPC won’t boot from this image. In order to make it bootable, you need to rename /WINPE/EFI/Microsoft/Boot/BCD(1) to /WINPE/EFI/Microsoft/Boot/BCD.

Awakening the beauty

What you can see on this photo is the very first startup of the most advanced OQO computer ever.

OQO model 02 is a very interesting high-tech device and a valuable item for handheld collectors. According to the spec sheet, there were three modifications of OQO model 02: good, better and best.

Any modification of the device is quite rare. It’s hard to find one in good working condition, with full package content. And the high-end model with 1.6Ghz CPU, 64Gb SSD and Sunlight Optimized display is especially rare. Not just because of the insane original price of $3000, but also because the 1.6Ghz models are prone to failure due to the well-known CPU overheating problem.

I was recently very lucky to acquire a new old stock version of the "best" modification (also known as OQO model e2) with full set of accessories. According to the item description, this device has never been booted to Windows. And it does look brand new. I was dared to make a power-on test. Now it’s one of the most valuable items in my collection.

GPD MicroPC arrived

Overall impression

MicroPC looks very robust. The build quality is quite impressive. Chinese companies definitely improve their skills. The keyboard is one of the most comfortable handheld keyboards I’ve ever used. The size of the device is significantly smaller than size of similar devices from UMPC era (see comparison photos below).

In general I really like the device. I can’t mention any disadvantages so far.

I did’t like the original GPD case, because it’s designed to fit much larger devices (GPD Pocket, probably). So I ended up using the FlipStart bag instead, because I have an extra one and the MicroPC fits perfectly.


The performance of MicroPC is significantly higher than the performance of Microsoft Surface 3.

DOOM 3 benchmark (1280×720, graphic quality set to high, timedemo demo1)

Device FPS (1st run) FPS (2nd run) FPS (3rd run) Average FSB
GPD MicroPC 10W 39.5 44.6 47.0 43,7
Microsoft Surface 3 30.5 31.7 34.1 32,1

It’s also worth mentioning that Surface 3 is unable to sustain this perofrmance during long period of time. Without active cooling Surface 3 starts throttling and the performance decreases to 23-24 FPS.

Recovering antenna covers of OQO Model 01

The case of OQO Model 01 is made of metal, it’s quite sturdy. However, the antenna covers are made of transparent plastic, which is prone to cracking.

In order to recover the cracked antenna covers I made a 3D model of the original antenna cover (antenna_cover.stl) and printed it on a photopolymer printer. I didn’t like the result, because the wall covering the antenna was too thin and fragile. So I decided to thicken the wall and sightly modified the original model. You can download the final model for 3D printing here: antenna_cover_fat.stl.
