Why do you think it needs replacing? What kind of Dell PC is it? Be advised that it's normal to have to hold it down for 4 seconds to turn it off. Jumping the pins on the motherboard should turn the computer on if the switch won't. If it will turn on by jumping the pins, then the switch may be bad, but it's not a very common part to fail. Replacing it should be pretty simple, if you have the replacement part.

More likely that the power supply is bad, or may be set to the wrong voltage (rear of the unit). (Desktop power supplies don't auto-switch for different voltages the way that laptop power supplies do.)

Dell 3537 laptop my vga adapter was changed but after that my laptop swithed off suddenly , sometimes it swithes on most of the time not switching on

Hello there
First things first:
1) perhaps its a bad VGA piece componet, or damage.
2) it will be connecting bad, on the mobo, or soldering
3) the swith for VGA and onboard its bad, or need to be check.
4) other than these, verify with your tech near you! for the VGA mode or inverter mode to VGA/Onboard .
Good Luck

Does your computer have an ON/OFF button (or slider) for the wireless, and a separate ON/OFF button (or slider) for BlueTooth?

Try each of the 4 settings:

Click Start
Click Control Panel
Click Network Connections
Click with the SECOND (usually the RIGHT) mouse-button on the wireless-adapter.

Hi i have laptop dell"inspiron 2200 when i swithed it on the laptop so it will get open and get stop than start making noise like tooooooooooooooo

Back up your data on an external drive now! It could be the optical drive or the fan but it is most likely the hard drive. If it is the hard drive making that noise, it is about to die. Saving a hard drive is unlikely. You can replace it but you cannot replace your data. Save your data now!
