A calculator could be one of the most accurate device ,but as much as it is accurate ,it also requires s great deal of maintenance just like any other device you know.
Maintenance helps increasing the effectiveness and longevity of devices especially the electronic once . being able to do this little maintenance technic would probably reduce the number of times you visit a technician.
Maintenance range from repairing damaged parts to replacing them entirely and I my case I did the replacement aspect of it.
My calculator was showing some signs of slowing down as the screen wasn't displaying properly,at first I thought it was the display screen that was damaged but after giving it a closer look I found out it was the battery that was down and I got a new battery and replaced it with it and now it works as new , with little ideas on this I literally fixed it myself.you too can do the same with a little practice.
