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!

Voltage can mess with digitizer of any touch screen. Most like the aftermarket power cord is drawing slightly too much power or slightly too less. My guess is slightly too much and when you are setting it on your lap, you are grounding that extra current. Find an original power cord and see if problem persists.
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.
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
