The power/battery settings are set for powersaving, rather than performance, so the battery lasts longer. If you set it to performance, the screen will stay bright.

Instructions to keep your Laptop Battery last longer


There are certain elementary rules for getting more from your laptop battery. Make it a point to turn off Wi-Fi and BlueTooth. You are aware that most laptops have shortcut keys to instantly disable wireless networking. Completely avoid playing computer games, music or DVD movies as multimedia activities tend to drain laptop batteries. Disconnect all external devices like PC Card modems, firewire, USB devices and optical drives. It is advisable to use the notebook touchpad instead of an external mouse. It will also help to adjust your screen brightness as dimming your display saves battery power. You'll certainly need to see your screen, but just how bright do you need it to be? Screens lighted at full strength eat up 15 percent more battery life than if your battery was at 50 percent brightness. So, be sure to squeeze more life out of your laptop by reducing the brightness of your monitor a great deal.
3711.jpg Select a laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity. Remember to decrease or mute the laptop speaker volume. Lastly, programs that are run from a CD or DVD can be copied and run from the hard drive, which typically consumes less power than an optical drive. Some games offer you the choice to install to the hard drive, so choose this option, as you will get more life out of your laptop than using the CD-ROM or DVD player, which are massive battery consumers. There are also some more tips to improve your laptop battery life. If you do not use your laptop for extended periods of time like a few days or a week, then remove the battery pack from the laptop. Never expose the battery to high heat or extreme cold conditions. For instance, do not leave your battery in your car during the summer months. Hot batteries discharge very quickly, and cold ones can't create as much power. Make it a point to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can qualify to full capacity. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
Energy management has been a problem since the earliest days of mobile computing. Drains on a battery include virtually every component on your laptop, including the screen, the hard drive, the CD-ROM and DVD-ROM, and other peripherals. The biggest villain is DVD movie, which cause the screen to run at full power for the life of the movie. Make sure you have no devices plugged into the laptop that can drain its power, such as a webcam, USB thumb-stick, or wireless PC card. According to laptop manufacturers, connected peripherals can impact battery life by up to 12 percent (depending on the peripheral), so get used to the touchpad instead of using an external mouse when you're away from an electrical outlet. As a ‘Prevention is better than cure’ philosophy, it is worth mentioning that air travelers should make it a point to recharge the battery before a flight. Find an electrical outlet while you're waiting for your flight at the gate, a restaurant, or departure lounge.

The LCD of my laptop brightens when the charger is plugged in, as the voltage from the mains is coming slightly higher than normal. i.e. 240v


What make and model laptop? What operating system? Many laptops default to a power-saving mode when running on batteries, dimming the screen slightly. When plugged in, there's no reason to save power so the screen is at full brightness. You probably have something like "Power Options" in your control panel that will let you adjust the power options so you can have the screen at full brightness even on batteries if you so wish.

My inspiron mini 10 wont turn on and it is plugged in. How do I turn it on? the power key does nothing


If your laptop won't turn on, you could have any number of problems. The problem might be a genuine power issue derived from either battery failure or simply a loose AC adapter. Conversely, it may only appear to be a power failure, and the problem may lie with another component. Errors in brightness settings and LCD display malfunctions can both make a laptop appear to be powered off, and all these problems will need to be corrected.

step 1
Look at the battery indicator light on your computer. Is it on? If so, check your brightness settings. If your laptop appears that it is not on, it may in actuality have lowered brightness settings. If the brightness setting is at its lowest setting, the laptop screen will be completely dark, and the laptop will appear to be powered off, even though it is not. Try cranking up the brightness settings.
  • Step 2 Check your AC power adapter. Is it snugly plugged into the wall or surge protector? Make sure the connection is made and it is not loose. Also, try connecting the power adapter into a different wall outlet.
  • Step 3 Check the status of your laptop battery by considering how long you have had the same battery. Most modern batteries are only good for about 1,000 full charges. After that point, the battery can and eventually will greatly deteriorate. Replace your battery if necessary.
  • Step 4 Replace your battery by powering off your laptop and then flipping it over and locating the battery cover outline, which will be near the bottom back of your laptop. Remove any screws with a Phillips screwdriver and pop off the battery cover. Slide out the old battery. Put in the new battery by sliding it in until it clicks, and then replace the cover.
  • Step 5 Consider replacing your laptop monitor. Your laptop may power on, but if the monitor display does not work, it will appear to be off and you will not be able to operate the machine. Check to see if your current LCD display works by plugging your laptop up to an external monitor using a VGA cable. If the external monitor displays your computer contents, your computer motherboard and underlying systems are still working, but your display will need to be replaced.

    My computer works great except when I plug in the A/C adapter...the screen goes black. I unplug the adapter, the screen comes back. The adapter does charge my battery fully. Can you tell me how to fix? ...


    Try using the 'increase brightness' buttons (usually accessible using the fn key and a key with a 'sun' or 'lightbulb'-symbol) on your laptop while the A/C adapter is plugged in. Some laptops remember the brightness levels in each state (battery and plugged in), and go to that brightness level whenever they're plugged in/unplugged.

    Dell laptop screen goes blank when ac adapter plugged in


    I believe I have found the problem with the 1525 that I am currently working on which has the same problem that you describe. Ultimately I think it's a problem with the inverter in the LCD. When the laptop is powered by battery the brightness is lower than full. When I plug in the power adapter the brightness goes to "full" and I hear a faint sizzle and the LCD's backlight goes off. Same as if you hold the Fn key and press the up arrow to brighten it, it will do the same thing when you reach near the full brightness. So for now I have fixed this problem by going in the Power Options and clicked on Adjust the display brightness on the left. Slide the slider to the left on the "plugged in" part and now when you plug it in it shouldn't make it go blank. I do want to note that I hear a faint buzz coming from the LCD when I plug it in. That must mean the inverter is faulty. WAY TO GO DELL!!!!!!

    Its not a problem, its how it was designed. With the power cord in it will be at full power so it will light brighter, When the power cord is out, it will be less bright as its using power from the battery , it will light dimmer to conserve power.

    AC power vs Battery power


    It would have done, because when running on battery the laptop goes into power saving mode and the brightness and processor would be slowed down. If you go into your power settings of the laptop, which will probably be in the taskbar as a battery icon, right click on it and you should be able to change the brightness settings or use the 'Fn' and the Star shaped icons normally on the right and left keys or within the power options in control panel.
