This week: Batteries-Replacement Needed?
All PCs have batteries; laptops have their running batteries and both laptops and desktops have batteries to keep the BIOS values set. The BIOS (Basic Input and Output System) is used to tell Windows or other operating systems what hardware is being used, with what specifications. As users, we first know there is a problem with the BIOS battery when the system date is not kept current when the PC is turned off. Without some power, the chip that holds the BIOS information loses its bits and has to check the hardware to reset the specs for Windows. But it has no way to know the date other than the default date of 1/1/2000 (some of the older PCs were 1900).
If you start getting security certificate errors from the web sites you frequent, check the date displayed on your monitor; if you have to change it every time you power up, it is time to have that battery changed. On desktops it is very easy.
On laptops, at least one access panel requires removing, but in some of the older laptops, they require taking apart--not well designed, but I think the original designers of laptops did not expect the PC to outlive the five-year battery. This brings us to the main battery on a laptop. This is integral to the workings of the hardware and Windows. Yes, if it is dead, your laptop will not work, but it will also cause other issues with Windows. A laptop I worked on had Windows working very slowly, and the touch pad and keyboard would not work, but an external keyboard and mouse would. By accident, I found the removal of the battery allowed everything to work. Windows noted that the battery was bad and should be replaced. That is as it intended to be, but I had never seen a bad battery stop Windows from working.
Another issue and this one can be dangerous, is if your battery is bad and your laptop keeps charging, it can overheat and either explode or get so hot as to burn skin. If your battery indicates being bad, remove and/or replace it.
‘til next week
