Total system uptime

Question

Hi,

Does anyone know how to find out the OVERALL system uptime on a PC? i am awre of the fact that you can find out information like this in the task mangager, but that is since the last boot. surely there is something on the pc hat records your overall runtime? if so, how do i access it to find out?

thanks

Answer 1

Hello,

I dont think there is anyway to do this.  As at the time of a restart, or boot, this information would be lost as it isnt able to be stored anywhere to be accessed again to be added to once the system came back up.  Everything i have seen shows only from the last boot.

What do you mean by "OVERALL system uptime"?  Do you mean the date that Windows was installed?

You can get a read out like this (includes other information too) by launching a Command Prompt and typing the command SystemInfo in it.

Original Install Date:     10/08/2009, 3:32:19 PM

System Boot Time:          4/04/2010, 2:49:53 PM

Don't ask me to convert that into seconds or minutes, that sort of information needs more fingers and toes than I have got.

i meant a readout displaying how long the system has been running in total since the OS was installed. every readout i found was from the last BOOT, instead of overall uptime.

Answer 4

Hello.

Although the question and last answer is sometime back, I myself was also curious about this, and didn't take this as a proper answer.  As windows and linux, and most other operating systems logs the time a system comes up, and down, it would be fair to assume, that one could calculate the total uptime and downtime of a given installed system.

Via google I found this : http://www.howtogeek.com/80068/easily-determine-windows-uptime-in-windows-7-vista-or-xp/

So, do check the below :

WinAudit - http://winaudit.zymichost.com/index.html - can give actual uptime and downtime statistics summed from the log files stores on your computer.

As for Linux, there should as far as I remember, also be a uptime tool, that will tell the total uptime logged for the installed system in question.

As a side note, unfortunately, intel have not embedded a counter in each cpu, storing actual running hours (nor at which volts/amperes/temps), but the winaudit is the next best thing.

Just thought I would respond to this thread, in case other people stumbled upon it.

EDIT_1: As a sidenote, when I double checked my own system, I saw that the logging might NOT have been from the actual install date as when i summed the uptime+downtime i came to a number far less than I knew the system had been installed in. So, do check the "Uptime Statistics" -> "Data Start" and compare with the cmd "uptime.exe" (see the EDIT_1_Link) -> "Original Install Date"
