If you have a bad battery in your laptop it should not prevent it from booting up when plugged in. However, it depends on how long your battery has been bad. When your battery goes bad it can start giving off chemicals. Those chemicals can get into your hard drive. When those chemicals get in your hard drive they ruin your hard drive. That prevents you from booting up from your hard drive. That makes your hard drive worthless. If you do not have good backups, you will spend a lot of money recovering the data from your bad hard drive. You may be able to boot up from a CD ROM or the internet depending on your computer.
No. When a laptop is plugged in, it immediately switches to AC power and begins charging the battery. The battery cannot become "overcharged" because special circuitry in the battery is designed to prevent this.
not really. if you take out the battery when plugged in you could short circuit the laptop. trust me i know.
its ok to do that but if you do it for too long then the battery wares out
Computers don't have batteries so I'm assuming you're talking about a laptop. Laptops with their battery SHOULD work when its plugged in. Some laptops can even work WITHOUT the battery but still plugged in. However, if your battery has a critical flaw (dead short) then even with it plugged in, it won't work. I suggest you try the laptop with the battery removed. If it works, that is the problem, otherwise, your laptop has other problems.
Not unless it is plugged into a wall outlet.
No, in fact if the laptop's battery is working fine it is best to NOT keep it always plugged in as doing that has the potential of wearing out the battery more quickly than if you don't keep it plugged in all of the time.
no, not at all i always keep mine plugged in
I usually leave it plugged in if I can, because why not keep your battery charged?
Make sure the laptop computer is receiving power. (Is the cord plugged in correctly?). When the laptop battery is installed in the computer and it is properly plugged in to an AC outlet, check to see if the fuel gauge is showing a charge sign. If this does not fix the problem, the laptop battery, the power source in the laptop, or the AC power cord may be defective.
Yes it destroy the battery
No, if you have your power plugged into your laptop all the time. Your battery will decrease its performance until your battery will last only a couple of minutes until flat.
No, as long as the power adapter is plugged in, the laptop will boot without the battery installed.
