Do you need a cmos battery for your computer to boot?

Most new computers can automatically determine the correct settings needed for your hardware, and some even store configuration data in a non-volatile Flash chip. These computers effectively do not need a CMOS battery for anything except maintaining the correct time. Older computers, where you had to specify the parameters for the hard drive in the BIOS, need a CMOS battery. Otherwise, you would have to enter them in every time you booted the computer.


Should you remove the battery when you have connected your notebook to power adapter?

You can with most laptops, but then the battery will not be charged. Try it - if the screen goes blank when you pull the battery out then it's off. For most laptops, you only get 1 battery pack out of the box and in order to maximize the battery's life time, once u have a fully charged battery u can remove it when u have an AC power on, so that the battery wont keeps on charging. Cant the laptop detects if the battery is full and cut off the charging? Yes, in most of the cases, but it is still a myth if hooking on both AC and battery together will shorten the battery's life time.

Why Do desktop computers have batteries?

They have batteries so that when the main power is turned off. The motherboard can continue to process the passing of time. Thus allowing the computer's clock to keep running. Otherwise every time you turned on your computer the time would be farther and farther behind real time. Principally to keep the real time clock working, although many computers use battery backed CMOS to store things such as hard disk parameters.

Does the hold button drain your iPod's battery?

Actually doing ANYTHING on your ipod touch whether it be listening to music, or pressing some buttons will drain the ipod battery. some things drain less battery then other things, but they all drain battery. (for example, listening to music does not drain as much battery as watching a video.) I do not know any buttons on the ipod touch called the hold button, but if you are talking about the button in the front with a square on it, that does not drain battery. if you keep holding it, a whole lot of options might open, but it does not drain battery. If it DOES drain battery, its so small of a drain that you won't notice it and it won't impact your ipod's performance
