Replacing the Battery on Your Casio Calculator Watch and Resetting the Watch

Posted by Russell Wright on June 7, 2009

Okay, so I’m a geek and I wear a calculator watch (most of the time). I’ve been sporting the Casio CA53W-1 since about 1980. I’ve had several.

Replacing the battery is not good for over 40 eyes. You definitely need some magnification! If your remove the 4 screws from the back you have a tiny o-ring that seals around the back and a CR2016 battery that is held in place with a clip. There is also has an insulator attached to the clip.

Push down on the battery to slightly flex the clip and use a small jeweler’s screwdriver to carefully detach the clip side that is located toward the keyboard. Once you hook it, it shouldn’t take much. Then, carefully remove the clip and insulator.

Place a new battery in the compartment, + side up, and hook the clip/insulator to the top hook and then press down to flatten the clip. Use your small screwdriver to carefully assist with attaching the bottom part of the clip. Don’t rip up the insulator!

After installation, you’ll have to perform a reset on the watch. In the lower right quadrant you should see a small gold contact on the circuit board with the letters AC (all clear?) stamped on the sheet metal backing next to it. It took a strong magnifying glass for me to see it. Temporarily short the gold contact to the sheet metal backing and the watch should reset itself to 12:00 a.m.

Put the cover back on with the teeny tiny screws and you should be good to go. Be sure to get the o-ring gasket in the channel correctly.

Cannot install or upgrade integration services in Hyper-V

Posted by Russell Wright on June 1, 2009

I found this little fix the other day and just wanted to post it as a good solution to the problem I was having.

I was unable to use the mouse (yes, I do know how to use the keyboard) when I opened one of my servers from Hyper-V Manager and was attempting to install integration services to resolve the problem. However, integration services would never install/upgrade. When I was attempting to install integration services, it would throw an error attempting to install the “Windows Driver Framework.” I would get an error “The system cannot find the file specified.” I found this post  that had the solution that worked for me.

Simply delete these two files:

C:\WINDOWS\system32\DRIVERS\wdf01000.sys and
C:\WINDOWS\system32\DRIVERS\wdfldr.sys

and then reinstall integration services.

This may or may not work for you, depending upon your exact problem. My VMs were moved from Virtual Server to Hyper-V.
