optional Windows Update “Synaptics driver update for Synaptics Composite USB HID Device” breaks some UltraNav USB keyboards

Posted by jpluimers on 2016/06/27

About a year ago, I ran into the optional Windows Update “Synaptics driver update for Synaptics Composite USB HID Device”.

It basically breaks the UltraNav/TrackPoint functionality of some USB keyboards like my 31P9304 USB TrackPoint keyboard (also known as SK-8835)

I bumped into this on another system as well, so I was glad I found this on an asian site: 联想ThinkPad|ThinkCentre|ThinkStation服务与驱动下载常见问题.

Below is the English translation of which the most important is the workaround: Install the Windows Vista driver from the Lenovo support page.

ThinkPad X201: fixing the “black screen” (without mouse pointer) after upgrading to Windows 10

Posted by jpluimers on 2016/06/10

After this Windows 10 boot screen the display goes blank without a mouse cursor.

After this Windows 10 boot screen the display goes blank without a mouse cursor.

So you upgraded your X201 from Windows 7 to Windows 10 even though it’s not in the listed on the Lenovo supported models page.

Now it gets through the boot screen, flashes the CapsLock/NumLock LEDS, blanks the screen (no mouse cursor) and continues booting without any visual feedback apart from the HDD LED flashing until it is finished booting

Since Windows 10 by default does not enable the F8 option any more, you need some more severe measures.

BIOS update

The first was to get the BIOS up to date. At the time of writing that was 1.40-1.15 from BIOS Update Bootable CD for Windows 8 (32-bit, 64-bit), 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP – ThinkPad – Lenovo Support (US):

Then I had to burn the ISO. Which was a bit picky because most of my infrastructure is VM based and none of the physical machines had a DVD or CD-drive any more. Luckily I found a LiteOn SLW 831SX which Windows detects as Slimtype DVDRW SLW-831S USB Device. ImgBurn worked with that (in Administrative mode that is).

Upgrading the BIOS went fine, but the symptoms stayed.

Removing/re-inserting battery

Removing the battery for a while, then reinserting was suggested at one of the sites.  It didn’t help.

Force into Repair Mode

Then I read this:

If the system can’t load the necessary configuration more than two times, the system will  direct the display to Windows RE(Recovery environment).

Source: Windows 10 – How to enter Safe Mode if I can’t boot the system successfully?

They also have: Windows 10 – If I can’t enter the system, how can I restore the Windows 10 laptop or PC to default settings?

This very easy to do:

Prepairing Automatic Repair

Prepairing Automatic Repair

  1. Keep the power button down to power off the machine
  2. Power up the machine
  3. Wait for the boot screen to appear, then
    1. Keep the power button down to power off the machine
  4. Power up the machine
  5. Wait for the boot screen to appear, then
    1. Keep the power button down to power off the machine
  6. Wait for the “Prepairing Automatic Repair” to finish
  7. Wait for the “Diagnosing your PC” to finish
  8. Wait for the “Automatic Repair” to appear, then
    1. Wiggle with the mouse to get a mouse cursor
  9. Press the “Advanced Options” button
  10. Choose “Troubleshoot”
  11. Choose “Advanced Options”
  12. Choose “Startup Settings”
  13. Choose “Restart”
  14. Wait for the reboot and “Startup Settings” to appear (note: no mouse cursor)
  15. Hit F5 for “Enable Safe Mode with Networking”
  16. Wait for it to reboot twice.

This didn’t work as well as I hoped as now I was at the failure point as well.

But now at least I had a starting point to trip Windows into booting any way I wanted. I now only had to find which function key would get me into a state where I could see what was going on.

And the good things: The “Diagnosing your PC” only required one ‘manual power down” to appear.

  • F9 – Disable automatic restart after failure
  • F8 – Disable early launch anti-malware protection
  • F7 – Disable driver signature enforcement
  • F6 – Enable Safe Mode with Command Prompt
  • F5 – Enable Safe Mode with Networking
  • F4 – Enable Safe Mode
  • F3 – Enable low-resolution video
  • F2 – Enable boot logging
  • F1 – Enable debugging

F3 finally got me to the VIDEO_DRIVER_INIT_FAILURE (BSOD STOP 0x000000B4) which indicated the machine was so hosed that I had to to a clean install.

Automatic Repair - wiggle with the mouse and you have a cursor too!

Reminder to self: SKU numbers for the ThinkPad UltraNav USB keyboards with horizontal Enter key and 6 rows of keys

Posted by jpluimers on 2015/12/14

IBM/Lenovo stopped producing ThinkPad UltraNav keyboards with 7 rows of keys a while ago. It stopped me from buying ThinkPad machines (together with the screen issues), but I still use the external USB UltraNav keyboards which are harder and harder to get.

So here some SKU/FRU/PN/EAN that seem to have a horizontal enter key and US layout.

Full size (with touchpad and numeric keypad):

Compact (no touchpad, no numeric keypad, although some pictures are wrong and show touchpad+numpad):

Need to check this for my ThinkPad W701: How to Fix Windows 8.1 Slow Performance Issues

Posted by jpluimers on 2014/04/13

Whereas Windows 7 was really fast, Windows 8.1 on my ThinkPad W701 is very slow in an erratic way.

Need to check out this:

Windows 8.1 proves to be extremely slow on their computers, with Microsoft yet to address the problem with a workaround or a patch.

According to some posts on Microsoft’s Community forums, this is mostly happening on Lenovo laptops and the fastest way to deal with performance issues is to uninstall the “Intel Dynamic Platform and Thermal Framework” from the device manager.

In addition, you need to access the BIOS menu and in the “Configuration” screen, make sure you disable the DPIF option to turn it off completely until Microsoft comes up with a fully-working fix.
