X band goes off at maximum alert level for no apparant reason and won't go off until power is cycled.

The reason why your monitor might not be recognizing a signal is because the graphics card in your pc might not be correctly plugged into a pci slot or your internal graphics may have a short somewhere. If the monitor turns completely off after it cycles Then it might be an internal problem with the backlighting in your monitor screen

Check to make sure that your clothes are not piled to one side causing the load to be off-balance. If that does'nt fix it then, It may be that your machine has a balance stabilizer on it that has worked its way loose or even off.

OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

If the unit shut off automatically, because it had reached the humidity extraction level you had it set on. It won't turn back ON again, until the humidity level rises above the setting you have it on. Lowering the humidity extraction level to 32 -35%, should make it start up again and cycle like it should. If your unit does not have an LED Screen, set the manual control on Maximum.Be sure the bucket is not full and the air intake filter is clean.

Hope this helped you to troubleshoot and solve the problem.

Does it alarm like this in another vehicle? Does it start this after you press a button to change a feature? The unit does have an auto off function that turns it off and it also has a "teach mode" that goes through all the alerts. This is why i asked if the unit starts this after you press a button as these two features can be engaged if you hold a button too long.

it is the auto leveling systems if it does it alot you may have a leak in the air system

Although the detector could have internal problems, it is possible that it is coming from a real source.
A route I took between home and business triggered mine along the same stretch every time I passed it and after looking a a map and comparing it with the stretch I drove, I found that the Marine airbase at Miramar California was visible (line-of-sight) between two mountains only along that stretch.

Note if the falsing happens at about the same point each time.
I just learned to ignore the laser alarm if it triggered during that 1-2 mile 'window.'

There could be several causes for this, but probably a bad timer. One test for this...when it stops...is to turn it off...and turn the timer slightly clockwise...to the middle of the rinse cycle...and turn it back on. Does it run then?? Try advancing it to the spin cycle after the rinse. If it runs okay after you manually advance the knob...the timer is probably defective.
