There is not yet support for the internal WiFi. I use the Mango Travel Router with this laptop to access local WiFi or my phone's hot spot. Mango comes with everything you need to connect to an access point.
Mango Travel Router: $65.00 USD
In the past, I have also used a TP-Link AC750 Wireless Travel Router, an Asus RP-N12 Wireless N300 Range Extender, and a TP-Link Nano Router. I include a folder of URL links to the admin pages of each of these routers to make it easy to set up the first time.

Power consumption is 16 Watts, measured with the computer booted to the desktop. This computer consumes less than 1 Watt if it's plugged in, but switched off. When charging a depleted battery, it consumes up to 45 Watts.
The laptop can use any memory left over from 32-bit usage as a RAM drive. For 8 GB RAM models, this RAM drive has 4.7 GB, and is formatted HPFS. For 4 GB models, the RAM drive is not configured. If activated, the RAM drive would have 700 MB.
This laptop boots to the desktop in under 60 seconds. That's important, because suspend/resume does not work. To make up for that, the laptop can do a clean power down when the lid is closed.
There is no ArcaOS support for the bluetooth. Support for the internal WiFi is under development at Arca Noae.
The disk is partitioned to provide bootable operating system volumes for ArcaOS and for Windows. Space is left for an addtional bootable volume. User data is stored on a separate volume.
ArcaOS 5.1 (first GA) is the version used for this installation.
The SysBench 0.9.5 program no longer works well enough to report its results. Blonde Guy has the source code and will fix the program when time permits. Until then, the only report will be CPU power from PassMark Software.

Each Blonde Guy ArcaOS preloaded computer comes with a standard load of software. This page lists what is in the current pre-load. This list is updated over time to incorporate new essential OS/2 software as well as to keep up to date versions of existing software. When you receive your ArcaOS preloaded computer, you will have Blonde Guy's best installation of the latest OS/2 software.
The recovery USB stick supplied is a bootable ArcaOS USB stick with a backup of the hard drive as delivered. You can boot the machine from USB stick, and perform maintenance functions. The maintenance folder is available on the recovery USB stick. The factory backup is stored in the \Factory directory. The backups are simple zip files. You can use 7z or unzip to extract some or all of the files in a backup.
This section documents what I did to get this computer to work under ArcaOS. It is intended to show what goes into this computer, and also as a guide to the user who wants to build it himself.
The installed BIOS is 1.37 (Aug. 14, 2019) and the EC is 1.4. These are the final BIOS versions for this computer.
I made the following changes to the default BIOS settings. Then I powered the Thinkpad down and up.
The Lenovo Hardware Maintenance Manual says to turn off the internal battery before opening the case, then remove 8 screws and pry 8 tabs to open the entire back of the case. The drive is easily replaced.
I booted the ArcaOS USB stick, and in System Maintenance, I prepared the hard drive using the Suntan Special application prepareSSD. I then restored the Factory build using RestoreVolume.
I installed one bootable volume, F:. The F: drive has a Custom installation that includes developer tools.
Sound is working normally on the laptop. Audio works well, both external speakers and headphones are working. The following modification is needed to enable sound. The Uniaud driver from Arca Noae provides sound through the internal speakers.
Using Suntan Special I run sequences ArcaOS51, apps, games, dev and cleanup. This is saved as the Factory image. This is normally what would be supplied on the computer.
If am external monitor, then this is how it will work. The computer is set to the native screen of 1920 x 1080. If your monitor is the same, then nothing needs to be done to switch to and from an external monitor. If the computer monitor is different than 1920 x 1080, then the screen resolution can be adjusted to the optimal values. For example, I tested with a computer monitor with a resolution of 1920 x 1200. When I switch to my external monitor, the computer changes to 1600 x 1200. I enter 1920 x 1200 into the screen applet and reboot for optimum resolution. When I switch to the built in display, the same action is needed.
