Thanks RKinner but what is it's function.

Keeps the clock running when the power is off.  First sign that it is going is usually the clock not being right on boot.  Also keeps the CMOS memory from forgetting any changes you make to the BIOS setup.

Thanks for that,

 

I have a Dell Vostro 220 that has been lying idle for a couple of years, was working OK when I switched it off. I was going to get it up and running for my niece but now it will not switch on. I have been trying all of the troubleshooting in the Dell manual but nothing seems to work.

 

The light on the On Switch Button is showing steady amber. As a last resort I wondered if it was the Coin Battery, but your response would indicate that that is not so.

Does the fan on the power supply come on when you turn it on?

 

Does the main fan come one?  It should normally start up fast and then slow down but should run continuously.

No nothing happens at all.

Either the power supply or the power switch assembly is defective.  If the motherboard had a failure it would usually try to start then fail.  I had to replace the power switch assembly on one Dell once but it was an XP.  You can test the power supply:

Suspected it might be that, I will get a power unit, but I will test it first.

many thanks.

Hi I tested the power unit as indicated in your link and the fan started OK, but still the PC would not switch on so I got hold of a used power unit and installed it and the PC powered up OK.

 

Thanks for the help.
