If a portable computer, such as a MacBook, quits when disconnected from outlet power, it probably has a battery problem. Take it to a service provider if you can not determine if the battery is dead yourself.
To keep the power supply cool. If there were no fan the power supply would overheat and fail.
Power supplies are the most common failure point in a PC. Check for these:Broken Power supply unit (even if nearly new)Lack of power in the cableBlown fuse20 or 24 pin ATX power connector not seated correctly4 pin CPU power cable not seated correctlycable from front panel power switch to motherboard connector disconnected
I believe this would be unwise, it would overload the power supply and it may overheat.
That would depend on the power supply.
It would be safer and to purchase a new power supply,a repaired power supply might pose a fire hazzard.
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
I would use a 300W power supply for a 250W appliance. It's recommended to have a power supply that can handle more than the actual wattage of the appliance to ensure efficient operation and prevent overloading. In this case, a 300W power supply would provide enough headroom to safely power the 250W appliance.
The MacBook is a great computer but it would not be officially classed as a SuperComputer.
I would by your first macbook pro form an official apple store.
I believe not. unless you pull the whole button off!
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
The computer will only consume what power it needs. No diffference. if you have a 350watt power supply, and it is using more then 70% power consuption, the life of that power supply will be short, so always aim big when picking out a power supply, ie: 50-100 watts more than what you would actually need.
