Changing the power button chip

by sondraglynn / February 26, 2008 9:43 PM PST

I have a Dell PC. The power chip on the PC has went out. I started with the power supply by replacing it and the computer will still not turn on and my next guess was the power button. I can see the chip but I can not get to it. Can someone tell me how to get to the chip?

There is a push button SWITCH but some might call it "chip"?

The item number is 88RXM rev A01. If you still need a picture let me know and I'll go find my camera.

Good news! That's no chip.

From all I can find, there are NO ACTIVE PARTS on that board. just 2 LEDs, push button, connector and the PCB. You should be able to test the switch with an Ohm meter.

Testing switch

How do you get to the switch. The casing for the hard drive and the floppy drive is blocking access to the switch.

Maybe I was too unclear.

I noted that the make and model of the computer would be needed. You gave me the part number of a piece of the machine. As such I can only tell that you can often find disassembly instructions at Since you didn't share the model number I will think that you will be doing this research.

It is an Optiplex GX260.

I did a quick check of the area you need to look at. It seems the "micro-switches" if they have failed can be repaired. If you're capable once the "control panel" is in hand, replace a possible failed switch(power). Otherwise, you can order a Dell replacement, but ordering the whole control panel pcb., using the Dell ordering process. You can try a quick reseating of that cable as well to see if a cable problem exists, it shouldn't but it can be.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
