Undervolting the Processor

I’ve always been annoyed at my laptop idling at around 80 degrees Celcius (according to RealTemp), which is totally unhealthy for the computer. Today I decided to do something about it.  I looked at how to undervolt my processor.  The process on the laptop is an Intel Core 2 Duo T5250, which runs at 1.5 Ghz.  It supports voltages between 0.95 V and 1.25 V.  I followed a guide (link at the end) on how to undervolt the processor and in the process I learned quite a bit.

According to the writer of the guide, undervolting simply reduces the voltage applied to the processor.  Since all processors have a different voltage requirement, they all use one standardized value which is most likely higher than the amount that the processor itself requires.  By reducing this excess voltage, the power dissipated by the processor will decrease, and thus reduce heat and increase battery life.  It should also be noted that this process will not impact performance since the performance of a processor is governed by its clock speed.

By doing this, I’ve reduced the temperature of my laptop by about 12-15 degrees Celcius.  The laptop’s keyboard and touchpad are no longer warm to the touch and the side heat vent no longer feels like burning.  Definitely a major improvement!

DVD Data Error (Cyclic Redundancy Check)

While trying to back up a DVD that I had, I came across a cyclic redundancy check error that prevented me from reading the disc with DVD Decrypter.  The error means that some of the sectors on the disc are corrupt.  Usually this error is caused by physical damage to the disc (can sometimes be solved by cleaning the disc), hardware (loose cables, or a bad drive), and DVD’s that have been poorly burned to begin with.  I found this to be a little strange since Windows Media Player could play this disc just fine, so I was convinced that I could still back up this disc.  I looked around for fixes for this error and here it is (for DVD Decrypter specifically, although this may work for other programs if the options can be found):

And since it’s been a while since I had burned a DVD, I couldn’t quite remember what to do with the VIDEO_TS folder that I got.  After the files on the DVD have been copied on the hard drive, I used the guide below to burn those files onto another DVD.

SolidWorks Side-By-Side Configuration Error Fix

I finally found the fix to the error in SolidWorks 2010 (also reported to work for SW 2011, 2015 and 2016) that prevented me from running the program.  The computer uses Windows 7 32-bit (works also for Windows 8 and 10 as pointed out in the comments), and every time I started up the program it would something like:

The application failed to start because its side-by-side configuration is incorrect.  Please see the application event log or use the command-line sxstrace.exe tool.

I used my Google-fu and found that the cause of this error is due my computer not having the Microsoft Visual C++ 2005 Redistributable.  A copy of the setup file for this is in the SolidWorks 2010 disc.  It is in the folder (DVD Drive):PreReqsVCRedist.  After installing that, the error disappeared and SolidWorks starts properly.

Dream A Little Dream

My dear friend has always posted many pictures and articles she finds interesting on the Internet, and I thought I’d share it.  There’s also a lot of pictures of food and various cute things, so if you’re interested in this kind of stuff, then this website is definitely worth a look.
