Time to say goodbye to my old laptop. I have had it for six or seven-year, and it has served me well. A few years back the hard drive controller started to exhibit issues, e.g. it did not always boot because it could not find the hard drive. Other times it worked fine, but any heavy IO operation would cause the system to hang. I tried replacing the drive, the ribbon cable, but neither worked.
I resorted to running the OS from an extern drive, so the laptop became a desktop. That worked fine for a while, but with more recent OS versions and more demanding web applications, it still showed its age.
