Some laptops have a default setting which alters the brightness of the screen based on the lux of its immediate environment. This can usually be disabled in the BIOS.
Sometimes the laptop has serval Power manager setting, the screen change brightness in the different setting, when useing battery, when using adapter , the brightness change.
Change the brightness of the screen sometimes works.
Lenovo has bad screen brightness. I have Lenovo G480 the screen is not bright even on power plug with maximum brightness setting. I should test the screen brightness before buy it. I have my old Acer laptop the screen is superb. After all Lenovo is a purely China brand...
Depends on the Max brightness of the Laptop you are talking about all I would suggest is to buy a light anti-glare screen for your laptop.
Hold down the Fn key (next to the CTRL key) - and press either F6 or F7 to change the brightness. Release both keys when you have the desired level. The screen will retain the level until you want to change it again.
Your screen might not support brightness. If you are on a desktop PC or using a monitor try the buttons on the front to alter screen brightness
There are probably buttons somewhere on the screen that allow you to change it.
It sounds like either a loose wire, or a 'dry joint' - either way, it's a job for a technician !
After you buy the best laptop under 1000 dollars, you need to take care of it. One thing that you can do is to turn down the brightness and the contrast on the screen. The sharp contrast between bright lights and dark colors is what can burn an image into the screen forever. If you turn the brightness down, you can keep the contrast from being so great. This will preserve your new screen.
NO. the processor is impossible to change (unless your gonna rip everything out of the laptop case) and the lcd screen, well, you can hook up the laptop to a normal desktop monitor, and display the screen on there, but fixing the laptop screen its self is near impossible.
Laptop batteries have a life expectancy of approximately 400-500 recharges, depending on the battery. To conserve battery power, simply decrease screen brightness and unplug the charger when the laptop is fully charged.
One thing that can make a big difference is reducing screen brightness.
