Intermittent Laptop Won't Power On Sometimes?

Well worked fine with just the power suppy (no battery) all week and then yesterday it would not power on. No matter what I tried. Tried the power button at least 80 times over a 8 hour period and the lights just flicker and if I listen closely I can hear a faint click, click sound. I tried again today and powered up on the first try.

Electrical fatigue? Is this repairable? Or not worth it?
 
Maybe someone else will have this problem with a D600 and I got it on another forum and this is a strange remedy. About 1-2 inches to the right of the power button, just above the "prnt scrn" button is a narrow strip of frame. If you press on the frame with good pressure and at the same time press the power button--the power comes right on.
 
i had this exact problem with all the same symptoms you have and the click noise
but with a sony vaio laptop i bought, turns out it was a faulty power chip on the mother board never ended up getting it fixed
basically the chip is either just faulty or the chip it has become unsoldered from the motherboard hence why pressing down, as mentioned above, will re-connect circuit and allow you to power on

Yeah, I though it really probably has something to do with the power switch or a chip or relay, something faulty. For now I just don't shut it down. Seems easier to just keep it in the standby mode. I'll probably buy a new laptop within a couple weeks and get this fixed.
 
Strange. That sounds like some of the innards have come un-soldered over the life of the laptop. This isn't uncommon.

To answer your earlier question, you may be better off replacing this unit. It could cost you just as much for a new one as it would to properly repair this laptop.
