The CMOS (BIOS) battery keeps the computer'a comfiguration and the Date & Time settings in the CMOS (BIOS) chip in its memory. When the CMOS (BIOS) battery is flat these configuration information is lost.
Replace the CMOS battery with a new one, in most cases this battery is a lithium 3 volt battery type CR2032 and it is coin size battery 18mm in dia.(check it to make sure the type of battery is installed on your motherboard).
When you replace this battery then go into the BIOS and set the Date & Time etc.

it sounds as if the key is bad (a crack in the metal or such) or that you may be inadvertently turning the key when you insert/ remove it before it is fully in/ out of the ignition.

It may be that the lithium battery is dead; usually a CR2032 button battery. Signs of CMOS Battery Failure Dom Tech Computer Blog

Go into the BIOS settings during initial power on boot up, often F10 or F2 are common. Check the date and time, if they are off, you should be able to temporarily boot by setting the date and time but you'll have to do it every time you boot. If the date and time is off, and you set the correct date and time and it still doesn't boot, you'll want to make sure it's booting to the correct drive.

When it doesn't boot, does it give you any error?

There can be many reasons...

• Your BIOS setting is not correct.
• CMOS battery is down(Most probably).
  
• both
  

You can open the BIOS setting page by pressing keys like DEL, F10, etc. depending on your system's manufacturer at computer startup(post screen). There are lots of wakeup options check them properly.
One of the option is "Restore last state of power Button on failure" which can turn on your computer without touching the power button. you should check these options.


And it suggest you to press F1 because your system's date/time is not configured properly. You can also set Time/date in BIOS also.
If your BIOS Battery(CMOS) is not weak or dead then after setting these values your computer should start properly.
And if your BIOS battery is dead then all the settings will be lost(date/time etc) after a restart and you will face same problem again...

Try changing the Power-button option and Date/Time in BIOS and see if problem persist....if yes then you have to change COMS battery that is on your Motherboard.

This oven needs the time set after a power failure. The LED display will read HELPME and there is a small knob on the left side you need to turn it to set to change the time and use the second knob from left side to + and once done leave the knob on manual. The oven can be timed to turn off but it the time is not set on it the oven and stove do not work.

HI there you camera internal CMOS battery is down need to replacement.

To change the time on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).
with the handset down, enter #20 the screen should say MMC DISABLED
1) enter in 1 2 3 4 1 # (that enables programming)
2) enter in #55 the screen should say YYMMDDWHHMM
3) enter in the year, month, day, day of the week, hours and minutes(the day of the week values are 1= mon. 2= tues. etc.)
press # when finished.

loud hiss sounds like a air line broke or 1 of the bags somehow got a hole in it

crawl under and follow the lines and look for damage maybe turn the key on so that the compressor is running and listen for leaks

You need to replace the cmos battery in your computer. Theu are usually Cr2032 batteries which you should be able to pick up for about £1.

unplug your computer and open the case.
When you look at the motherboard you should be able to easily locate the cmos battery cliped onto the mobo.
Take the old battery out and insert the new one.
put the case back on and plug the pc into the mains again.
You will need to re-enter the date etc the next time you boot up, but the settings should be retained after that.
