When using laptop on lap, screen blanks out and turns fuzzy
I have a T40, and it works fine if it is placed on a flat surface such as a desk. But when any sort of pressure is exerted on the case unevenly, the screen blanks out and freezes, which is an extremely aggravating problem. I have narrowed down the part of the case that seems to cause the blank out- it is below the left side of the keyboard, above the pentium sticker. Is there a component directly in this area that would cause the screen to short, and is this a common problem? Any help would be appreciated, I have never disassembled a laptop but would not be uncomfortable doing so. Thanks!

Hi! first, i would like to ask if you are using cooling fan? if does, then i'll give you some tips on how to keep your laptop from overheating
1. Turn off your computer and allow it cool down.
2. Work with your laptop on a flat surface. The rubber feet on your laptop are designed to allow airflow to the underside of the computer, so if you are working on a bed or other soft surface, you cut off the airflow. If you do want to work away from a desk or table, try keeping your computer on your lap, exposing the underside to air.
3.Shut down your laptop before placing it in your carrying bag.
4 Give your laptop a bit more lift to increase the airflow under the machine. Two simple, flat rulers placed along the front and back edges of your computer is enough to increase the flow of air and keep your laptop cool.
5 .Unplug your charger as soon as the battery is full. A common mistake people make is leaving their computer plugged in at all times. However, the constant source of electricity will heat your battery and in turn overheat your laptop. Only charge your computer as long as necessary.
The reason is because when the laptop is placed on the bed the cooling vents are blocked and the CPU overheats and shuts down. When the laptop os placed on a flat surface there is sufficient clearance between the bottom of the laptop and the flat surface of the desk to provide sufficient air circulation.
If you wish to use the laptop in bed then place the laptop on a flat surface and not let the bed clothes cover the laptop's cooling vents.
Well it is possible to install a new screen relatively easily... It is a bit of a mission, Ya need to get a replacement screen & driver board and do the reverse procedure from removal. A screen can be got from say, Ebay, or the net. Otherwise get a reputable place to do it for you.
On the second Thinkpad laptop, that doesn't show a display with an LCD screen. Plug a VGA monitor into the VGA port on the back of the laptop. Hold the Fn key down, tap once on the F7 key (Toggle your display over to an external monitor)
Give the VGA monitor a few seconds to come on. (It's a VGA monitor)
Do you have a display on the external monitor? No? You May have a bad GPU then. (Graphics Processing Unit,
Fix? Change out the motherboard. Possibly Ebay has one, dunno.
VGA monitor has a display? Then you may have a bad Inverter. The Inverter provides power for the LCD screen. Inverters go bad.
Are both Inverters the same? (Laptop to laptop) BE SURE. The Inverter MUST match the LCD screen! Check the numbers on both Inverters. If they are the same, switch the good one over to the 2nd laptop. See if you have display now. No? Then it's the GPU.

I want the asker to be able to see where the link takes them, by looking at the link. I feel it helps make the asker more comfortable with my solution, knowing I have their best interest in mind.

First, to verify if it is your display adapter, connect an external monitor to your laptop and see if it displays fine. If it is fine on the monitor, then we know that it is from your laptop screen(in this case, it is either you first check from a technician if it is the colour that has to be refilled or if you need to purchase a new screen). If not then it is from your display adapter(could be from corrupt display drivers). In this case, you would have to re-install new drivers for your display adapter(you can download it from your system manufacturer's website if you don't already have it). Thanks
