"How much is the tax exempt of electricity bills and home working allowances during telework?" -The story of small and medium -sized enterprises that suddenly introduced telework (38) company telework assistance, how much tax exemption is exempt.

Friday, January 29: Check PC power consumption in 1ms

　During the telework, I work on a laptop paid by the company.To examine this power consumption, a free software called "Joulemeter" was installed.

　Joulemeter is a software provided by Microsoft, and it is possible to automatically determine power consumption if it is a notebook PC.However, since UAC authentication is required at installation and startup, verification will need to be performed with a machine administrator.

　After launching the software, turn off the notebook PC and confirm that "Select Calibration Setup" is "Running on Battery".If you click "Perform Calibration", the power consumption will begin, so wait as it is.After about 2 minutes, the power of the monitor disappears, but wait without worrying.wait.Five minutes later, the monitor was displayed for a moment, but I waited again because it turned dark.wait....... No, how long should I wait?

　I wrote "Don't touch the mouse or keyboard", so I just waited for about an hour, but there was no movement, so when I displayed the screen, it seemed that the work was over.I wanted you to take some action, such as turning on the monitor.

　When the "Power Usage" tab was opened in this state, the power consumption of the CPU and monitor was displayed in real time.In addition, click "Start Saving" to leave a log, so select the location and name of the file.I will work as usual for one hour.The following log files were created as a result.

　The log was saved in 1ms units, so the number of lines was ridiculous.Enter the AVERAGE function at the end of the "Total Power" column to determine the average value.Looking at the calculation results, the average notebook PC is about 4.It seems to be consuming 82W power.If this is applied to the previous formula, the monthly electricity bill is about 20 yen.Recent laptops have excellent energy -saving performance, but I was surprised that they were so economical.

　By the way, the desktop was selected to save the log file, but the file was stored on the desktop of the administrator user instead of the user in the login.I feel Microsoft's strong will, saying, "I must never inform my employees about PC power consumption."

　Some large companies are paid for teleworking expenses in the form of home working.However, looking at this result, I felt that the "calculation method of the business use part related to electricity charges" did not match the actual situation.Even if the company is paid beyond this, it is very complicated that the government will bring some taxes as taxes.
