Default HP case on/off switch - sticky

Anyone here have any good ideas to repair a HP computer case ON/OFF
switch? On start up, it seems to get stuck behind the lip of the front
panel, turning the computer OFF after a few seconds. It only started
doing this after two years of use. A thin letter opener freeing the
switch *quickly* does stop the shutdown. Thanks.

Remove the front panel, enlarge the hole slightly, replace panel.

May result in slight cosmetic defects and could affect the "at auction"
price estimate in the year 2212 version of Antiques Road Show. "A pity,
but somebody drilled out this front panel slightly. Would have been
worth 23,500 newbuks to a collector but I'm afraid, in this condition,
only perhaps 2,000."

Could also be possible to shim the switch outwards, or brace it so that
it doesn't depress below its opening. Your heirs will thank you. ;-)

Nope. Without a model number, I can't tell what style of switch
you're trying to fix.

Don't pry on it with the letter opener. Tear apart the front panel
and clean out the dirt, dust, sand, hair, fur, food, crud, etc that's
between the plastic switch plunger and the case. Sometimes the tiny
push button switch behind the plastic button gets encrusted with crud
and becomes sticky. HP has disassembly instructions on their web
pile. However, without a model number, you're on your own.

Thanks. I was thinking of a fine file or Emory board on the edges of the
1" square opening. Now...to get the front panel off.

Don't have a model number. It was built by a third party using mainly
HP parts. Belarc reports HP Pavilion 061 PL308AA-ABA a735w 0nB1211RE101KELUT00
It's got about a 1" square opening for the switch, which turns blue upon
power on.

Looked but could not find. Pile is a good description. Got a link? You
sayin' I can blame the cat for this?
