Presario SR 1055CL will not turn on I believe its the on off switch


If the computer started giving you trouble turning on before it failed, it is probably the power supply and not the switch itself. To check, you will need to take the computer case off. There are usually 2 power switches on a pc. The first one disconnects the incoming line voltage completely. Make sure this switch is on before you try the other power switch. The second power switch actually starts the computer. The power disconnect switch is a toggle (or latch), that is, it retains its position. The switch that actually starts your pc is a momentary contact switch. To test the momentary start switch, you will need to take the cover off. Be careful not to damage anything and watch out for exposed voltages. If you pay attention, it is not dangerous. All you need to do is short the 2 wires that go to the case switch momentarily. Once shorted, the motherboard latches on until a power failure or shutdown. Note that you do not want to keep the 2 switch wires shorted, since this will prevent the pc from booting. Just short them for about as long as you normally push the power button in. If the switch is bad, they are not usually difficult to replace. You should be able to find a part number on the switch, as well as manufacturer. While it seems like all the case switches are custom per model, they are not. The actual switch itself is actuated by a plastic button on the case.

How to reset toshiba laptop to factory settings. Without original disc


Toshiba laptops from mid 2007 onwards dont have a recovery disc supplied with a purchase of a laptop. Instead, Toshiba has added a hidden partion on the hard drive which contains the same files on a recovery cd / dvd.

To reinstall your laptop to the factory settings / "out of the box" settings, please follow these steps. It worked for me, and should work for you.

ALL DATA WILL BE ERASED ON YOUR HARD DRIVE IF YOU PROCEED. YOU WILL NEED TO ENSURE THAT YOU HAVE THE POWER ADAPTER PLUGGED IN. DO NOT SWITCH OFF OR RESTART YOUR COMPUTER DURING THIS PROCESS.


1) Hold down the power button for 10 (ten) seconds to switch off your machine.

Please note: Holding down the power button on the machine forces it to switch off. Any unsaved data will be lost.

2) Press and hold the 0 (zero) key and at the same time, tap the power button once to switch on your notebook.

3) When the machine Starts beeping; release the 0 key.

4) When prompted by the warning screen; select Yes to continue with the system recovery.

5) Select Recovery of Factory Default Software; click Next.

6) Select Recover to out-of-box state. Click Next again.

7) Click Next to Start recovery.

I hope you find this step by step solution helpful for you.

Thank You

Compaq 5000 Series Desktop


Hi,
Everythings Fixable. If you locate the power switch Cable To Motherboard. Should be marked ( pwr on Motherboard )
use a hard-drive jumper. small plastic link block. to join the 2 connections on the board itself. ( Jumper )
now plug the mains cable in, if it runs. then you know it,s the switch thats faulty. you can replace this with any similar make break switch. alternatively. if the case has a seperate reset switch. use that instead.
