Maybe the display brightness is low. Go to Control Panel and check somewhere. Also, look for a brightness key. My F7 and F8 have brightness up/down in rectangles.
Press the 'Fn' (Function) key and press the brightness up key. You're up and ready. Go, enjoy!

My acer aspire 5313 works when connected to externel screen and has a dim screen when using the screen. i have changed the screen, inverter, and signal cables but still same problem. i looks like the...


Hi Daniel,
The LCD screen displays is dark/ dim because there is no backlight.
There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. But most likely it is the CCFL (Lamp). Its life is limited and depending upon how long it has been in use, you can have a better idea - if its the CCFL or Inverter.
(Rest assure that your system/ motherboard is ok as you have checked it by connecting you laptop with some external display, which is working fine). Hence, the board/ graphics processor is OK. (In case the graphics processor fails, there is no display at all on the external monitor)
So, my advice is that you check the laptop LCD display for replacement of CCFL. I have found a general link about CCFL replacement. Click here for detailed and graphical DIY instructions about LCD disassembly.
Make sure you take proper precaution while working inside LCD, as the inverter generates a very high voltage.

Hope it helps! Good Luck!

I have an hp pavillion laptop that has not worked in a few months first the screen was black when you turned it on. now i can see the screen somewhat but not 100% its dim please help


Have you tried connecting an external monitor? If an external monitor works good, then you'll have to replace your lcd screen. You may be able to replace it yourself. You can purchase a service manual for you laptop online through ebay. If not then it's going to be your internal display adapter and that will require a trip to the shop.

Hi There, I've been experiencing the same setback as Kenneth. My lenovo 3000 flashed off and even if I boot it, the screen is still black.How ca I fix it?./ Ty


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

The in my HP Pavilion dv5000 laptop is ditorted but when I hold from the top it will work?


I think your problem is LCD. To make sure, try entering the bios when your pc starts. You can enter bios by pressing F10. If within the bios setup utility, your problem remains same then yoy need to change the LCD.

Backlight only stays on for a few seconds on compaq c700 that is only a year old


When the external AC power supply is unplugged from a notebook, the LCD display will dim to conserve on battery power. During times of heavy battery power operation; such as during the startup or boot process, the display may be very dim or barely readable. If the display remains dim when the notebook is operating on the Windows desktop, follow the steps below to resolve problems with display brightness Restart the notebook with AC power Follow the steps below to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the power button for 5 seconds.
  3. Press the power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected, try changing the LCD brightness. Adjust the LCD brightness using the function keys From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8 key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers ( f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be familiar. Check the movement of the Lid Actuator switch The Lid Actuator switch is available on some models. It is a small button or switch located above the keyboard near the hinge for the LCD. Pressing this switch when the computer is on may turn the notebook display off, or it may cause the notebook to enter a different power state. Press the switch two to three times while observing the display. If the display does not return to normal brightness when the switch is released, the switch may be sticking and need to be repaired. Contact HP service and support for further assistance. If the display turns off when the switch is pressed, the power management function may be set to hibernate or turn off when the lid is closed. Install updated BIOS and drivers To resolve certain hardware and software issues, use HP Health Check to automatically search the HP web site for an updated BIOS as well as any updated software and drivers. To launch HP Health Check, follow the steps below.
  1. Click Start , type health into the search field, and then select HP Health Check from the list. HP Health Check displays a list of available BIOS, software, and driver updates for your particular model.
  2. Click the description link for any BIOS, software, or driver updates, and then follow the on-screen instructions. You can only install one update at a time.
  3. Repeat steps 1 and 2 above for all updates that you want to install.
You have now installed the available BIOS, software, and driver updates for your particular computer model. Contact HP service and support If the display remains dim after doing the troubleshooting steps listed in this document, contact HP service and support for further assistance.
