Re: screen turns dim

Omg thanks haha been fixxing up my "new" d630 had many issues with it trying to play basic games such as warcraft 3 the screen being dim was annoying^^... for others having issues with d630 gaming i suggest rolling back your display driver from A07 to an earlier A06 version you will no longer have random blue screen crashes.. also i8kfanGUI allows you to be able to control your fan to high mode which dramaticlly helps this model function properly and delays the dreaded "time to clean out the dust" time of year :p

What is the life of my satellite l30-101 battery off the ac charger

Toshiba's line of Satellite PC laptops offers a variety of screen s that are customizable when ordered online. The laptops offer built-in webcams and backlit keyboards. Most Toshiba Satellite laptops use six-cell lithium-ion batteries that can last up to six hours. To reach that six-hour mark, you can use several tricks to maximize your battery's capacity.

Charge your battery completely before its first use. Check your user manual for the exact charging time required, which is typically at least 12 hours. Discharge your battery completely every two months. Allow it to drain fully before recharging it. Recharge it completely, for at least 12 hours before using it again. Remove CDs and DVDs from your laptop's drive when not in use. These drives spin when loaded, which can drain your battery unnecessarily. Set your laptop to hibernate mode when you need to take a break. This conserves more power than standby. Store your laptop battery in a cool place. Never let the battery sit in direct sunlight or leave it in your car on a hot day. For even longer battery life, remove the battery from the laptop which can get hot while in use when you are plugged in. Turn off your Wi-Fi connection when not in use. Constantly searching for a Wi-Fi connection can drain your battery faster. Work in only one program at a time. The more programs you have open, the faster your battery will drain. Unplug any USB devices, especially those that charge when plugged in, such as your cellphone. These will drain your battery quickly. Dim your Satellite's screen to conserve battery. Hold down your "Fn" key and tap "F6" several times to dim the screen. The "F6" key should show an open circle with small lines radiating out, to symbolize a dim display.

I have a hp 6735s laptop that i bought recently and when the adapters not plugged in the screen keeps going bright for a second then dull how do i stop this?

So you mean the screen goes dimmer when you remove the AC POWER ADAPTER?

If so, then this is due to the POWER SAVER mode that most laptops use for when not plugged into AC.

In control panel (if using XP) there should be a POWER MANAGMENT or BATTERY MANAGEMENT icon or section. In here there are usually settings for what you want the laptop to do with regard to power under different scenarios (ie. No adapter, with adapter, etc).

In the settings there should be an option to turn off power saving mode when the AC adapter is not plugged in.

Well, the battery is it's own separate module. The battery most likely will just pop out of the laptop wherever it is.

The AC cord is a power supply ran from a normal household outlet. It also charges the battery. So, you can both charge the battery and run the laptop at the same time. The battery is probably only going to be used on the run anyhow. :) So, you can just use the AC cord whenever you have access to an outlet.
