I recently noticed that my CPU fan on my Acer Aspire 5002 WLMi notebook was running at full speed much more than it normally should and the system itself was running more slowly than usual. When I opened task manager I was finding a process called Monitor.exe was hogging anything up to 99% of the CPU. I terminated the process and that solved everything – usually until I rebooted.
But what to stop this happening again?
It turns out that monitor.exe was related to Acer eRecovery – a tool that helps recover your laptop from a major crash. However after a bit of googling I found out that it needs the D: partition that comes with the laptop (apparently it needs to be in FAT32 as well, but I don’t think this is true because mine had been NTFS for months and I hadn’t noticed any problems).
The problem seemingly arises because I recently reformatted the D partition into a few ext3 and other partitions for installing Linux (Ubuntu to be precise). Since Windows can’t read Linux filesystems, eRecovery can no longer find the D: partition which it, for some reason, seems to need.
Simple solution? Well I disabled Monitor.exe using Start -> Run -> msconfig and disabling Monitor.exe, which was listed at the bottom of the list under the Startup tab.
