My phone constantly shuts itself off. Sometimes even after I've logged in and just put it down for a few moments.

are you talking about the gas grill or the fire place logs?

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

The internal board is gone. You need to get it replaced, although may be cheaper to buy new PA Speakers.

Power down the Canon Pixma IP4300. Once it has shut down, leave it off for a few moments.
Hold down both the "Resume" button and the "Power Button." When the printer begins to restart, release the "Resume" button but continue pressing "Power."
Push in the "Resume" button twice, then let go of both the buttons. In a moment, a green light flashes a few times.
Press the "Resume" button four times once the green flashing has finished.
Push the "Power" button again until the printer shuts down. Wait a few seconds, then press the power button again to restart the device. The Canon Pixma IP4300 will now function properly. for more information http://www.fixyourownprinter.com/forums/printer/67824 hope this helps you.

It is either an overheating problem where the acer is shutting off to protect the equipment, or it is RAM that has gone bad.

Try cleaning out all the vents and fans as well as you can. If the unit is no longer under warranty, you may want to open it up if you can to ensure a good cleaning. If that is not the problem, I would investigate replacing the RAM.

change the battery

the solution to these change the battery
