I manage a few physician offices' IT equipment and one office in particular has had a sudden outbreak of computers zapping out. The laptop in question is the Panasonic Toughbook CF-C1. The issue is users will get logged in to the laptop and start their programs and within a few minutes the screen flickers a few time then the entire computer powers down. I have seen this issue on 3 separate laptops within the past 2 weeks, all in the same office. All of the computers were purchased at roughly the same time so I suppose it could be an age thing, however it seems like a huge coincidence that 3 laptops would display the exact same issue within a 2 week period. The office has approximately 20 of these laptops in use and there are about 50 more spread out across the other offices but none of the others are currently, or have ever, had this issue.
Here is what I have found so far:
I checked all of the chargers in that office for shorts - Nothing
I inspected each of the affected laptops for damage or signs of shorts - Nothing
Windows logs are showing a kernal power critical error.
Moving the laptop to the same model laptop will cause the new laptop to exhibit the same behaviors.
Replacing the hard drive in the affected laptop corrects the issue
I am about to pull my hair out trying to figure out what is causing all of these laptops to suddenly go bad. From my findings above I can logically conclude that the hard drives are the issue, but I want to get to the source of the problem and see what is causing the hard drives to zap out the laptops. I would hate to replace the hard drives and have something cause them to go bad as well. Any information or guidance would be greatly appreciated.
