I have a failed microswitch on an ON/OFF power switch. Can I just cut the wires from either side of the switch and connect them together to bypass the bad switch without damaging anything?


you can get the switch from a local computer shop. It is a temporary switch meaning if you kept holding the button it would turn back off.
you might try: http://www.used-pcs.com/store/pc/home.asp
they sell used dell products including switches. but the cheapest way would be to go to a computer shop and ask them for a switch for a dell tower. Good luck.

How to turn on the wireless card on Sony pcg11211L


If your computer will not connect to a wireless Internet signal, one of the first things to check is whether your computer's wireless switch is turned on.

Many laptop computers have a switch located on the exterior of the computer that controls its ability to connect to wireless networks.

This switch can be accidentally turned off, preventing users from connecting to the Internet.

Determine if your computer's wireless connectivity has been disabled by viewing the network icon in the lower toolbar on your computer's desktop.

When there is a disruption in your computer's Internet connection, the icon will have a red X through it. For further information, go to the computer's Network and Sharing Center where you can troubleshoot connectivity issues and view available wireless networks.

If the computer isn't recognizing any wireless connections (and you're sure that there are wireless signals in your area), the likely problem is that the wireless switch is turned off.

Locate the wireless switch on your computer.

It may be located on either side of the laptop or along the back or front.
If you aren't sure whether your computer has a wireless switch, check the user guide that came with the unit.

Determine whether the switch is currently in the "On" or "Off" position.
The switch will be clearly labeled.

Push the switch in the direction of the "On" position to ensure that it is turned on.
If the switch was already turned on, see if there is a keyboard combination that will activate your laptop's wireless capability.

The key combination for your laptop will depend on your computer's manufacturer, but will generally involve a combination of the Function, Control or Alt and the F1 to F12 keys.

Check your user manual for your computer's key combination.

Just received Refurbished Advent CBE 1401. It is being replaced because power switch is faulty - but I have questions about machine. 1. When initially switched on the switch turned red is this normal? I...


1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

http://en.wikipedia.org/wiki/VGA_connector

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

http://en.wikipedia.org/wiki/Digital_Visual_Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

http://www.directron.com/dvi.html

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

To be continued in an additional Comment.

My e-machine desk top does not power up.


There is a way to bypass the switch and start the computer, just to verify that the switch is the actual problem....the only thing is it requires you to open up the computer case. If you are not comfortable doing this, I would take it to a computer shop. I don't want to see you damage your computer!

Here are the directions:
  1. Open up the computer case
  2. Find the wire that is connected to the front switch
  3. Follow the wire to the motherboard and disconnect it from the 2 pins it is connected to
  4. Take a screw driver and touch both pins at the same time (Picture Below). This will create a connection, as if you pushed in the switch and should start the computer.

Now if the computer doesn't start , then you know the problem is not the switch and will have to further troubleshoot it. If it does start, try going to e-bay and searching for a replacement switch

The button I push on my 2004 pc sticks and it won't hardly work to turn on my pc. Should I just leave the computer on to save the switch?


Well the problem with that is if you leave the computer on it will have to be restarted at times. Which should be fine if your computer will reboot by itself.

Or you could buy a new computer case and switch all the components into a new case. Of course you could always mickey-mouse it by wiring a switch you can find at a computer parts store or another old case. But you would have the switch wires and all coming out of the case

I bought a belkin cable a couple of months ago in order to switch between two pc,s on one screen.Unfortunatly i forgot which buttons to press on my keyboard to switch screens can you help please


I may be behind the times but this is how I do it. Get a monitor data switch ($5-$10 used).On the back of the switch, connect each computer to input ports & the monitor to the output port. Set the knob on the front of the switch to each computer as you boot it. Turn switch to each computer as needed. You will have to turn a knob instead of pressing a key. If you can live with that it works great.

Push switch, no power.


It can be the power supply. Does the power supply fan work when you push the power switch ?
