Screen is blank when the computer is turned on


The IBM ThinkPad is a brand of laptop computer developed by IBM. In 2005, Lenovo bought out IBM's laptop division. ThinkPads are like most laptops in that their screens are one of their most delicate features. If a screen is exhibiting problems, knowing how to troubleshoot the issue can save you a headful of worries and get you to the source of the problem.

No Video If you are experiencing no video from your display, make sure the laptop is powered on. The ThinkPad has a power status indicator on the body and will be illuminated if the computer is turned on. Once you verify that there is power, check that the laptop is not in sleep mode by holding down the "Fn" key for 10 seconds. If you are not in sleep mode, try to toggle the ThinkPad between external display and internal display mode. You can do this by pressing down the "Fn" button with the "F7" key. b> Verify Working Internal Display If you are not receiving any video when your computer is on, there is still a chance it could be a software issue. Turn off your computer. On the ThinkPad A, G, R, T, X and Z series computers, you can boot up in a basic level of the computers operation called BIOS to verify that the screen works. When you restart the computer, press and hold the button according to your model to turn on BIOS. This will either be "Press F1 for BIOS Setup Utility," "To interrupt normal startup, press the blue Access IBM button," or "To interrupt normal startup, press the blue ThinkVantage button." You can find out how to access BIOS for your particular ThinkPad model by referring to your owner's manual. Removing the Screen If you have a picture on your screen, but it is faint as a result of lack of light, adjust your brightness settings by holding down the "Fn" key as well as the "Home" button. If you do not get an adjustment in brightness, you may have a faulty backlight or inverter. If it is the backlight of the screen, you may need to change the inverter board. This is a small circuit board that controls the brightness of your LCD. If your computer is under warranty, take it in to Lenovo and have it repaired. If it is not under warranty, you can attempt to take it out yourself by removing the screen. For this job, you will need a screwdriver as well as a knife. Remove the screws around the screen housing and remove the small plastic covers with your knife to get at hidden screws. Use your knife to pry off the front bezel of the screen. The bezel is a plastic piece that frames your LCD. Remove any screws from around the LCD screen to remove it. At this time, you can replace the inverter board, the LCD panel or the LVDS cable--the low-voltage differential signaling cable that that sends graphics from your computer's graphics card to your screen.

You will need to remove the bios battery in your laptop. Here are instructions for an R40, I assume it will be similar for a R40e:

Blank screen upon startup


Try taking out the hard disk, plug in power and see if you have a display on your screen or external monitor. if same thing happen, try taking out the memory card. If you hear a beep sound it's a faulty mem. card, if no beep sound appears I suspected it's a motherboard faulty.

Sounds like it is asking for the power supply to be plugged in before it can start, which indicates a bad Battery, if you are allready plugging in the power supply unit, you may also have a bad or wrong power supply unit,(check that it is set too the correct voltage setting for your country too either 120V or 240V.) Possibly you know someone with the same working laptop so this can be verified by using thier working Battery/powersupply unit or as an alternative can both your battery and power supply unit be taken to a computer or electronics outlet store for simple bench testing before deciding on replacement. Lastly it may be a powersave mode or setting that has been activated before the last shutdown in this case press and hold the power on switch down, until all the lights go out. Leave it turned off for 30 seconds and restart. Press the esc or delete button on startup (before any screen info comes up)and adjust the power save mode setting in this systems bios.
