My computer shuts it self off for no apperrent reason and at differrent times. sometimes it will stay on a minute sometimes it will stay on a hour. i dont even have to be using it for it to turn itself off

things that happen to older laptops are that over time there tiny processor power supplies build up with lint from the air that is passed thru them sometimes even making the tiny cooling fans in there stop , then its only a matter of a few minutes and it overheats and shuts off , after several hours cool own it will restart , but wont stay on long , then the cycle repeats . if its caught in time and no power supply parts are ruined sometimes a Pc repair shop can dismantle one and clean it

What brand of pc is this? Download a diagnostic program to test internal functions. Sounds like maybe a motherboard or power supply issue.

It is a capacitor. Please read up on how capacitors work and it will explain itself.

The capacitor is holding a charge, just like it was designed to do.

take the cover off and see if it needs cleaning it sounds like thermal shutdown (overheating) after you have checked and or cleaned it start it up and make sure all the fans are working.

Sounds like your pilot is dirty, with a can of air blow ( with gas off) directly into pilot. Do that a couple times, then relite.

Display connection faulty, take apart and check connection from the display screen.

In order:
1 and 2) Clean the coffeemaker by puring in 1/3 caraffe vinegar, and 2/3 caraffe water. Either use the self-clean light or brew it as if it were regular coffee - just press the on button and then press the self-clean button, and it will begin.
3)
The Automatic Shutoff Time can be programmed
anywhere from immediate shutoff
after completion of the brew cycle up to four
hours. When the coffeemaker shuts itself off,
two tones will sound. Four hours is the default
time. The 0:00 setting shuts the unit off immediately
after brewing is complete. To check the
current setting, press the “On/Off” button and
the Automatic Shutoff Time will be displayed.
To change the preset time, press and hold the
“On/Off” button until the red “power” light
begins to flash. This signals that you have
entered the “Set Automatic Shutoff” mode.
Press the “Hours” and “Minutes” buttons
to scroll forward through the digits until
desired time appears. The first setting which
appears is preset at “4:00” and the next
display will be “0:00”, since four hours is the
maximum Automatic Shutoff setting. Pressing
and holding either button will allow you to
scroll continuously, slowly at first, and then to
accelerate to the rate of about three digits per
second. As the desired time setting approaches,
release the button and then press repeatedly
to advance one digit at a time.
The Automatic Shutoff Time (ASO) may be
programmed either before or during coffee
brewing. You may also re-program the ASO
time when brewing has been completed. If you
do so, the Automatic Grind & Brew™ will automatically
account for any time that has already
elapsed after brewing. For example, if you set
the ASO for 40 minutes and 25 minutes have
already elapsed, the Grind & Brew™ will shut
off automatically after 15 minutes (40 minutes
minus the 25 elapsed equals 15 minutes).

Good luck!

It is activated by a temperature switch. It's probably bad. Just runs the fan at any time for no reason or there is a short in that part of the system. I hate that the computor was changed first. Find that sensor and swap it out and see if your problem doesn't go bye bye.

Good luck

check to see if our tv timers are on weekly or sleep timers may be causng the problem and shutting down and a given time

when is the last time you changed the lamp ?  are the fans clean
