All,

I have a 15-16 month old MSI GE70-20E laptop (out of warranty) that is beginning to exhibit strange behavior with the power (on/off) button.

If the unit is off I have a very hard time starting it. I press the button and the light turns on (amber) and the system begins powering up but then shuts off before hitting the BIOS. After that happens I cannot get any response from the power button and I have to either remove the battery or the AC source and try again. Sometimes this process can take 30 or more tries before it comes on. So I have been leaving it running.

I can close the lid and the machine sleeps, when I open the lid it comes alive, as long as it did not hibernate (which I have disabled) so this is a workable short-term solution. Reboots are also fine since it is never in a fully powered off state.

The bit about removing the power makes me wonder if it is actually the switch that is going bad, other than that it seems like the internal connectors for the power button may be loose. It acts almost like I'm holding the button down too long causing a start up and in 5 seconds (or less) shut down.

Any ideas? Can I buy a new switch and install it myself, I have the mechanical skill, just wondering if it is even possible to buy parts like that?

Yes, it can run on the AC adapter with the battery removed or just the battery. The issue is starting it when completely powered off.

I'm still thinking I have a failing switch or connection, not a dead one because (so far) it will eventually work if I keep trying. But it is just a hunch.
