Laptop care! (Electrical power tips)

15 09 2008

Well, this is yet another general-help post. Doesn’t really have anything with Ubuntu, but it’s important to know a few things.

One very important to keep in mind when buying a laptop (and any other li-ion battery based device), is to:
Let it charge completely for a few hours before the first use! This varies from one device to another but most devices need 8-15 hours of charge the first time. Read your device’s instructions for more information.

Also it’s very important to: Let the laptop’s battery cycle every once in a while. If you keep your laptop plugged into the electricity the battery will lose it’s capacity and when you need the battery it might be damaged to the extent of not being able to keep the laptop on for more than 10 minutes. I’ve seen this happen a lot of times, and batteries are expensive. So take your laptop for a walk around the house once or twice a week. Also try to avoid leaving the laptop plugged in for long periods of inactivity, for example, all night long. If you finished your work at night unplug it and let the battery rest.

Most laptops, if not all of them, have a little box in the middle of the charger, most times one part of the charger plugs into it and it has another cable at the other end which goes connected to the laptop itself. Look at the screenshot for reference. (That’s my Toshiba’s charger).


This little box is a transformer (most the times) and it can get very VERY hot. So try to keep it where it gets some fresh air, and avoid putting it in closed areas or near heat-sources, like heaters, behind a monitor, near an engine, and so on.

And last but not least, avoid using your laptop (or any other device) in hot climates. In some countries a room’s temperature can go as high as 115 F degrees…and that’s suicide for any electronic device. If the laptop or device is forced to work under those temperatures the insides of it can melt, causing a whole mess of trouble. So try to keep it cool…know what I mean?… =)

Hope this was helpful! 😉
