How To Test a Smoke Alarm Battery To Find Out If It Needs Replacing

A smoke alarm is a excellent device that can detect if a fire is occurring and can alert you that there is a fire, by creating a loud "Alarm" beep sound, it is a device that can save your life. But if the battery in your smoke alarm is dead, flat or faulty, then the smoke alarm will not work and you will not know if there is a fire, this put your life at a high risk. So it is ideal to test the battery inside the smoke alarm, to ensure that it is getting enough power to work.

1)Get access to your smoke alarm, there should be a large button on the plastic casing that says "Test". Press the button down, if the smoke detector beeps, then the battery is fine and will not need replacing. If it doesnt beep then the battery is dead, or the unit doesnt have a battery attached to it.

2)There are some cheap fire alarms that dont have a "Test" button for you to press down and to check if the battery is dead. If you fire alarm doesnt have the test button, then remove the battery from the smoke alarm. It should be inside the smoke alarm and a 9 volt battery attached to a small battery snap should be connected to it. Once you have removed it, get a battery tester and insert the 9 volt battery onto it. If the needle on the battery tester swings to the area that says "Charged" then the battery is fine. If the needle on the battery tester doesnt swing at all, then the battery has no power and will need replacing.

How To Fix PS2 Slimline Loud Noisy Cooling Fan Make it Super Quiet!

So why does my PS2 slimline have a noisy fan?

The reason why you hear the cooling fan inside your PS2 slimline spinning like crazy is because the internal hardware inside it is suffering from overheating. Overheating can occur if your console is not getting proper air ventilation around it, since it blocks that airflow. Overheating overtime can cause the graphics and processor chips to get damaged. So the best thing to do right now is to start making some changes before its too late.

Instructions:

1) Examine your ps2 slim console, locate the rear and front air ventilation vents and look carefully into them. If you see that they are really dusty, this results in the hot air inside the case to become trapped. This is not good, so you will need to give them a clean. Dont blow the dust out with your mouth, because you might be thinking that the dust is gone, but really you are blowing the dust back into the insides of the console. So I would suggest using a household vacuum cleaner to perform the cleaning, since it will be sucking the dust out and not forcing it back in.

2) Ensure that your PS2 slimline is getting proper air ventilation around the positioning of the console. The air ventilation vent, found at the back of the console is used for the cooling fan to extract the hot air out of the case. So make sure your console is not pushed right against a wall, shelf or cabinet because it will allow air to escape more freely out of the console.

3) If you find that the cooling fan becomes loud and noisy after long periods of continuous use of the PlayStation 2 slim console, then switch if off and dont use it for about 10 minutes. This will allow the internal hardware to cool its self back down to a cool operating temperature. The slim model is more prone to suffer from overheating because of its small internal design and small sized cooling fan, in comparison with the older fat style model.
