No. The laptop charger+ battery serves as a UPS. A UPS serves to deliver a constant, reliable stream of electricity to your computer by charging an internal battery from an external power source, then delivering electrical power from this battery to your computer.

With a laptop computer, this functionality is already provided by the laptop's internal battery and external power cord.

Your laptop already has a battery -- it's kind of redundant. The point of a UPS is to prevent your machine from crashing hard whenever the power goes out. It's basically just a big, external battery.

Your laptop already has a battery that will automatically kick in whenever you unplug from AC. So no, you don't need a UPS for your laptop. Although an extra battery could ocassionally come in handy...

Depends on how you use your laptop Laptop batteries are lithium and don't keep a memory of partial charges, so if your power goes out you can pick up where you left off when the power comes back on. I would recommend a surge protector when charging your laptop. UPS units do not make sense for laptops because they are not portable.

That would totally defeat the purpose of a laptop. I don't think you would get much use out of a UPS unit -- save your money and spend it on Unbox movies :) .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
