It isn't always possible to be near an outlet to keep a charger running. A laptop is supposed to be portable. But a user may still need to be on their computer more than just 2 or 3 hours their batteries allow them. That can turn into a real problem if the person can't keep their computer running because lithium stock its battery just died.
This model has a 8.9-inch touch screen display. It is a LED back-lit display and supports a variety of multi-touch gestures (which was a lot of fun to use!). The screen can be rotated 180 degrees to face outwards. Some of the other features includes a VGA port, 2 USB ports, audio jacks and a memory card reader. Instead of using the usual lithium-ion battery, this model is powered by a lithium facts-polymer battery.
The lithium-ion battery is light years ahead of the earlier batteries and considerably better than the Nickel-cadmium (Ni-Cd) or the nickel-metal hydride (Ni-MH) batteries which are still being used. These batteries are less expensive but the Li-ion batteries are far superior in three ways.
You lithium bettery stock do not need all the sounds. Using heavy mp3 ring tones, keypad tones, vibrating and other chimes together are unnecessary. If you want a ring tone, switch off your vibrating mode. If you are using vibration then turn off mp3 ringtones. Turn down the overall volume of your phone as loud mobiles can be annoying and prone to battery wastage. Remember that vibration mode drains out most of your battery power.
Li-ion cells have a good peak output current and low source resistance. When you overload the tool, the voltage stays up, and they just keep pumping current into the motor. Power tools have thermal overload trips in the motors, and that's a good thing with Li-ion batteries, if they didn't they'd just burn the motor out!
Recharge the battery to full again and repeat the above steps a few more times. This will allow you to use the battery for a longer time and you can do this no more than once a month. Replacement batteries can be expensive and stretching out their use when you are on a budget can help.
