My power button is broken? Stopped working...please help?

My power button has stopped working.

Regularly, I press it lightly and it would start my computer up no problems.

Now, it is almost completely rigid, there is a slight movement, it's not crooked that I can see anyway, and absolutely nothing happening with my computer, no sounds or lights that I can see.

I've replaced the power battery thingi and the the power lead and still no change.

Has anyone had this problem and can let me know a solution please ?

From what you are saying here the power button is not depressing when you press it. Thats a sign of being gummed up.

Lets try this: with the systems power cord disconnected, get some household spray cleaner dampen a paper towel and wipe the button area, pressing it on & off so the cleaner can work its way in, don't flood it! As you don't want the cleaner to drip on the insides. You may need to apply a clean towel to catch the dirt.

Did that help? It not try some isopropyl alcohol (85% or better) this time. Again, using a paper towel this time at the end try spraying the button cutout area with a short blast of can'ed air.

Any better? The last thing here is to try a little (and I do mean LITTLE) lube. Take a cotton swab and spray some WD-40 onto it so its just slightly damp. Again, wipe the button cutout pressing the button on and off so the lube can work its way in.

Let us know how it goes!

I had an issue with a power button not working recently. I took the whole machine apart, removed the power button and glued it back in to place, now it works fine. I believe the issue was that the ring between the outer button and the inner part fell out of place and wasn't letting the power button be properly depressed. It's very important to test the button and hear the click when you press it when you glue it back in to place to make sure it is perfectly centered otherwise it will not work.
