Community Newsletter: Q&A forum: How do I stop Windows from reassigning my external drive letters?

If your computer keeps losing its settings, the first thing I would do is check the date and time on the computer. If the computer has lost the correct time and date settings, then the cause of your issues could be a dead battery on your computer's motherboard.

Fortunately, batteries are usually fairly easy to replace. Most motherboards use CR-032 lithium batteries, which can be found in many stores. They have a similar shape as watch batteries.

To replace the battery, you would first have to remove the outside cover from your computer. As cover designs vary, follow the directions from your computer manufacturer on how to do this. If your computer is still covered by a warranty, you may have to take the system to the shop. If you open the computer, your warranty may become void. Check the terms and the conditions before opening your computer.

Once the cover is off, remove the old battery from the socket. You could use a small screwdriver to get the battery out. The new battery can be put into the socket.

After the new battery is installed, put the cover back on your computer, plug in the cables, and power on your machine.

When you first turn on the computer, you may be prompted to accept the computer settings. Follow the on-screen instructions as to which key you should press. If possible, choose to enter setup so that you can change the date and time. Save the settings and exit the CMOS Setup. Boot the computer up.

I hope this helps.
