Power down My V3 turns itself off after approximately 10 minutes.

Open a door . It's suppose to do that . After 10 min. or open a door is what should shut it off . If not ,stuck RAP relay contacts stuck closed . supplying battery voltage all the time . RAP relay - Retained Accessory Power

Relay Controlled RAP
The BCM keeps the RAP relay energized during all power modes, except Off-Awake and Crank. The relay is also energized for approximately 10 minutes after shutting the ignition OFF and removing the key, providing no door is opened.
Relay controlled RAP will end when one of the following conditions is met:
• The BCM receives an input from any door ajar or open switch indicating the opening of any door after the ignition key is out of the ignition.
Important: If the BCM is receiving any door ajar or open signal from those switches when the ignition key is turned OFF, RAP will not initiate.
• The BCM internal timer for the RAP expires after approximately 10 minutes.
• The BCM detects a decrease in battery capacity below a prescribed limit.
Systems powered by the accessory relay during the retained accessory power (RAP) power mode are as follows:
• Power windows
• Sunroof

Try unplugging. Hold power button in for 10 seconds. Plug back in.

Simultaneously press the [CHANNEL UP] and [CHANNEL DOWN] buttons on the front of the DVD Recorder for approximately 10 - 15 seconds (until the unit powers off).

Disconnect the wall outlet. Wait for 10 minutes. Then power up.

It this still does not help....and If you are capable of taking the risk check out DMR-EZ47 Firmware Installation Instructions
Panasonic DMR EZ47 Installation Instructions Manual

Familiarize yourself with all the steps and especially the page 7,8 before you attempt this,

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.

Hello

Wait for five minutes if the motor stopped itself and has been stopped for less than 10 minutes. This occurs in the event of an overload. If this is the case, the dishwasher will reset itself in approximately 5 minutes.

Turn off the dishwasher and unplug it from the power supply. Wait 10 minutes and restore power.

Select a "Hi Temp" wash cycle, followed by a heated dry setting on the dishwasher.
Repeat step 3. This will reset the dishwasher.

It sounds like you computer is shutting itself off because the cpu is overheating. I would suggest making sure the thermal grease between the cpu and heat sink/fan is replaced and if the heat sink/fan isn't the best consider purchasing a new one.

The new laptops are not compatible with some of the older model routers.Try turning the power to the router for approximately 10 minutes,shut down your laptop before turning off the power to the router.once the router has been off for ten minutes,turn your laptop back on,as if you are "logging on",let your laptop be idle for about 20 minutes,giving your router time to "reboot" If this does not fix your problem,you'll have to replace your router with one that is more compatible....

check the capacitors on the power pcb,the tops will be swelled,replace the swelled capacitors,this should correct the problem,if not replace the power pcb

it sound to me like your power supplie is heating up and shuting down your power supplie is on its way out
