Computer switches on then about 20 to 30 min it switches of and it takes about 1 to 2 hours to come back on

Take it back or call for warranty service.

It's probably a thermal problem with a component. You should take it into a repair shop as it is not user serviceable.

Have you ever unplugged the unit in its current location? Try unplugging it for 10 minutes and plugging it back in to reboot the computer control. Other than that it's time to call in a pro.

Hi,

If you disk drive won't open then:

1)reset the PC bu unplugging all the cords from the back for 1 hour.After 1 hour plugin all the cords and then press and hold the disk rive button.It will come out.

2)If the **** drive still won't open then take a paper clip and insert it into the hole.You will find this small hole beside the button of your disk drive.You will have to insert the paper clip in it and press and hold for 1 min.It will come out.

just look above the brake padel, in front under the dash it have two bolt,10 or12 mm. remove bolt take
out wire harness then reverse watt you did then you
put it back easy to do about 20,30 mi.

you set it up online first that only takes 10 mins. setting up your devices then only takes about 10 or 15 mins and tell your installer to switch to decaf...

Take the minute hand off and turn hand over. There is a brass bushing that attaches to the aluminum hand. Take a small screw driver and place in the square hole of the brass bushing. Turn either direction and test on the minute post of the clock. Keep adjusting until the clock chimes right on the 1/4 hour position. Make sure to put the hand back on the right 1/4 hour.

Do you mean BIOS settings or WIndows was re-installed?

If BIOS setting then there is a jumper on the mainboard - obtain manual (or tell us what mainboard it is) and then use the jumper (link) on mainboard to reset CMOS.

The other way is to disconnect all power and then remove small button cell battery from the computer, then press power button.
Then wait for 1 HOUR before re-inserting battery and powering up again.
If you switch on before 1 hour then you will have to wait 1 hour again. If 1 hour is not long enough wait 2 hours or overnight. (usually it takes 20-40 mins to discharge capacitors).

Move the second button from the left to set, enter the time in 24 hour format via the HH and MM buttons, then move the button to start. The far left switch, on/auto.off is for the chime. Set to on for 24 hour alarms, set to auto for no chime from 11pm til 6am, set to off, to turn it off.

most fault codes are 10, 20,30.........90 not familar with c2. ther is a fault earky on in a prog where if the pressure switch does not retun to empty the prog stops and displays 10 or 30. the pipe leading from the front of the sump to the pressure switch can sag. tieing it up to stop the sag can cure this..
