I'm going to presume you've gone through all your settings to make sure nothing changed. If you haven't, you can do this by going to 'display' in your control panel.
How long have you had the laptop for? LCD displays unfortunately do fade over time. The life of one is roughly 3-4 years. Lamps can be replaced - I'm not sure if this is cost effective for you, though. Your mileage may vary.
Hope this helps! Good luck.

Dim screen acer 5100-3019


Try going into power option settings and taking the brightness to the max there. Start, control panel, power options, then you should see a setting for battery and for plugin. Hope this helps.

Need the full model information

Example,
Acer Aspire 5535-5050

Primer:

An LCD screen does not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on the monitor icon

Because of this the LCD screen needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or more than one), or a series of LED's.
(Light Emitting Diode)

CCFL = Cold Cathode Fluorescent Lamp (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.
Average thickness is 2mm, or a little more than 1/16th of an Inch.
Or about the width of this capital letter -> O <-
Average length is almost as long, as the LCD screen is in height.

(Do they break easily when trying to remove, and replace?
OH, YES!)

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.
If the laptop uses LED backlighting, it MAY or MAY NOT use a screen Inverter.
Generalized thinking (Can also be stated as 'Rule of Thumb'), is that if the laptop uses LED backlighting, it does NOT use a screen Inverter.

I also feel into this line of thinking, since none of the LED back-lit laptops seemed to use a screen Inverter; that came to the shop.
I have found this to be a fallacy from on here,......FixYa.....
I have looked up two laptops using LED backlighting, and discovered they also used a screen Inverter.

Now I post LED backlighting may, or may not use a screen Inverter.
Seems when LED backlighting first came out, a screen Inverter was used on some models.
Also seems as the LED backlighting technology progressed, no screen Inverter is used.

90 PERCENT of the time, the fault for bad Backlighting can be attributed to a bad screen Inverter.
Of course, this IS IF the laptop uses a screen Inverter.

For a laptop with LED backlighting that does not use a screen Inverter, and backlighting is bad (Dim, or non-existant), the next hardware part in the diagnoses to replace, is the LCD screen.

I now await the information I asked for above.
Then we can diagnose together.

Boots up but black screen


If your laptop screen is not working and is blank, you are out of luck as far as working on your computer. However, while there may be a major problem you need to troubleshoot, there are some easy solutions to keep in mind as well, such as brightness settings and your power source.
1.Check the power source. While you have presumably already attempted to turn your laptop on and off, the problem may lie with your AC power adapter. Is the power-indicator light on the adapter on? If not, your problem may lie here. However, whether or not you have a power indicator light on your adapter, consider unplugging it and plugging it into another outlet. This may turn on your laptop and take care of your blank-screen problem.
2.Check your brightness settings. While it seems like a simple oversight, the brightness on your laptop may sometimes be turned all the way down. Thus, the screen appears to be black, off or defective, when the problem is simply that the brightness is on its lowest setting. To fix the brightness, check your laptop keyboard. Most laptops have the brightness settings mapped to two keys at the top left of the keyboard, accompanied by a symbol (often a sun). Use these keys to fix your brightness, but keep in mind that some laptops require that you press the Function key at the same time as the Brightness key.
3.Check the status of your laptop battery itself. There should be a battery indicator on the laptop that is connected to the battery. This indicator is either on the bottom of the laptop or (likely) on the side. If there is no indicator, your battery itself may be the problem, and may require replacing. Keep in mind that older batteries of the nickel-cadmium variety are more likely to decharge over time and forget their initial maximum charge level; this may be a particular issue to users of older laptops.
4.Find a VGA connector and hook up your laptop to an external monitor if the above steps have not alleviated the blank-screen problem. Turn on the computer and the external monitor. Does the external monitor light up? If so, the blank screen is likely due to a video subset problem/LCD problem in your laptop.
5.Consider that a deeper problem may exist if the external monitor did not light up This problem may lie in the motherboard. In this case, taking the laptop to a professional repairman or sending it off to the manufacturer is recommended.

My acer aspire 9300 screen is so dim i can barely see anything


Hi.

      Have you tried adjusting the Brightness of the Display? May seem like a stupid thing to ask, but some laptops come with what is known as Ambient Light Sensors and by setting a higher brightness level it Disables the Ambient Light Sensor kicking in.
