I have a Samsung laptop with Windows 7 installed. I tried to buy a new on/off switch without success but now I do not think it is faulty after all. I think something more obscure is happening. It's wierd.
Scenario:
1. Open laptop and press switch. May work but usually not, so I
2. Insert a USB stick and press again. Probably works this time. May take 2 or 3 presses.
In the first case, if the power light comes on we're good to go but usually there's no light, not even a flicker.
In the second case, press (or press and wriggle) until light appears. POST begins.
(Keep button pressed for 0.5 - 1 second. Releasing too soon results in lights out, no boot.)
I hate intermittents but in all my years I have never encountered a problem like this where hardware depends (sometimes) on whether other hardware is present or not.
Tech friend suggested changing boot priority from USB, CD, HDD to HDD first. Haven't gotten around to trying that yet but can't really see how boot priority could affect what happens before POST begins.
Anyone seen anything like this?
Suggestions anyone?
