My faithful T40 served me well for many years, despite some rocky beginnings, but the old beast was just not cutting the mustard anymore in regards to its performance. I needed something faster and more capable. So enter a new Thinkpad. I was on a tight budget, so I went with a L412 because it met my requirements and it was affordable.
Now I'm having buyers remorse due to an issue I've been having lately. The issue is that the system will completely and totally freeze. No cursor movement, no response at all. If there's audio playing, it will stick, nothing moves on the screen. You get the picture, total lock up. The only way to recover is to press and hold the power button to shut it down and reboot it.
Unfortunately, I'm not sure what exactly causes this issue, but it behaves like it's a thermal problem. For instance, I watched several YouTube videos. It was fine after about 5 videos. On the 6th video, about midway through, it freezes. I reboot, resume watching the video (after checking the event viewer, to no avail) and maybe 30 seconds later, it freezes again. I reboot, go back to the video and try to watch it again. Same deal as before, it freezes. I reboot again, this time with speedfan open so I can monitor the temperatures, and it freezes again like before. But the temperatures didn't seem too high to me, around 50C or so. Maybe 55C at one point, but never above that.
But the experiment isn't repeatable. I can watch several videos and it won't freeze. Sometimes, I'm not watching videos at all, but simply working inside a VM. Recently, all I was doing was playing KNetWalk inside a fedora VM (VirtualBox) and it froze. The only other thing I had open was a Firefox instance.
My system is fully up to date with the latest drivers, BIOS updates, etc.
I'd appreciate any light anyone can shed on this issue. Since this was an eBay purchase, I think a warranty claim is out of the question. The seller claimed it's still under warranty, but I wouldn't have thought that was transferable.
If you need any more information, just ask. The specs for the machine can be found in my signature.
