Extending the life of your laptop battery

Laptop battery can only last for sometime. The only thing you can do is maybe extending it for a little more time. This is true for all types of battery - high-end Lithium-ion, NickelCadmium (NiCad) or nickel-metal hydride (NiMH) and basically for all brands of laptops and netbooks (Acer, HP - Hewlette-Packard, Dell, Gateway, MSI, Asus).

Some ways to extend the life of your laptop battery:
- good practice of using the original or right charger and the right specifications
- a regular dose of full-discharge and recharge, maybe once a week is recommended.
- It's also a good practice to avoid direct heat or exposing your battery to sunlight. It will be of help if you use a laptop cooler. Laptop cooler will significantly lower down the temperature at the back of your laptop, avoiding heat for your devices - hard disk, memory modules, processor and also for your laptop battery. You can notice this by yourself. Turn on your laptop for a 5 to 10 minutes. Feel the back of your laptop. Now, install your laptop cooler and feel again the back of you laptop after ten minutes. Notice a significant difference in the temperature?
- If you are using your laptop for a long period of time, for an 8-hour office work, it's good if you fully charged your battery and then remove it from your laptop (see proper instruction on removing the battery). Next is to connect your laptop to your adapter and continue with your usual work. This will give you laptop battery a needed rest. You can adjust your power setting for your laptop to hibernate once you closed the lid of your laptop. This will ensure that you still save you current working environment if you wanted to also take a rest.

I have a samsung S500 and when I turn it on the lens doesn't open or extend and it will beep 3 times and shut off. I have tried new batteries and nothing works. I took it to a camera shop and they


Well, have you ever considered that the lenses MIGHT be defected? If it's true, you can send it back to the manufacturer, as long as it wasn't YOU who made it defected.
Another tip, is maybe the lens isn't made for that type of camera.
Lastly, the lens can just be broken, so you should carefully examine it, and see INSIDE of it, to make sure all of the parts are their. Hope this helps (:

Apc unit is shuting itself down whenever PC unit is turned on, and then its alarm gets stuc. Also, sometimes it shuts down whenever another electrical appliance in the room is turned on. (Like a TV)


Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

A faulty inverter circuit won’t deliver power when the mains supply fails.

The true UPS types are usually the higher KVA units (over 1500 VA) that supplies uninterrupted mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power therefore there is no switch over time lag from the mains to the battery.

Computer turns off by itself


I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE. The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared. If you are computer savvy, then try the following - if not, take it down to a computer shop! 1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back. 2) Remove the 3 screws which hold in the heat sink in place. 3) Remove the heatsink 4) Take the dust out 5) Re-assemble a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste. Good Luck!
