It means it is time to search for the reason. Is it plugged in?
I mean it saves power, but I just Hibernate it.
An uninterruptable power supply is a power device for a computer (or other things) which is designed never to lose power in the middle of crucial operations. For example, if you're running a computer which is in charge of a critical process and there is a disruption in the power coming into the computer, the uninterruptable PSU (power supply unit) is designed to make sure the computer doesn't stop the process it was working on and lose data.

If you mean Data, then the part that receives the signal would be the network adapter. This could be the wireless adapter on a laptop or the Ethernet port on a regular desktop computer. Although, now a days most have both options. If you mean power, the power supply draws the power from your outlet and sends that power through out the motherboard and to individual hard drives, optical drives, SD card readers..etc
In computer Math, Giga is 2 raised to power of 30 bytes.
The power supply unit must be toasted.
It is unsafe both for the computer and you to work on a computer while it is plugged into a power supply. If you mean simply to use the computer, then no, it is perfectly safe as long as the generator doesn't generate more power than the computer can use. (probably 120 V)
To provide power to the computer from a power source.
If it is a computer power supply it is the box that gives the computer its power from the outlet.
POST (in uppercase) refers to the power-on self-test; the message might indicate a failure with some of the computer's hardware.
it means it isn't using power from the battery. it is coming strait from the outlet...aka battery is charged and its not using battery power
If the power adapter isn't plugged in before the computer is powered on, then the computer will not power on. The power supply provides power to the rest of the computer (which allows it to boot). If the power supply doesn't get power, then the rest of the computer doesn't get power. This doesn't apply to a laptop if it has a charge stored in the battery.
