This is a known issue with the T40 series. I have the same problem. It's a result of a manufacturing defect introduced through a new soldering process Lenovo used on this series. Basically, they baked the motherboard in an oven instead of soldering the components on one by one. This resulted in many of the graphics chips not fully connecting. After normal use, a corner can pop up, causing the screen to go blank if you move, lift or jostle the laptop.

As far as I know, Lenovo doesn't offer any fixes for this. If you wish to risk it, you could try soldering the loose corner yourself. Some people found a wedge works well. I stuff carboard between my keyboard and the chip to keep it down. Other people hve been known to use post-it notes.

Where can I find a schematic or instructions to open my toshiba satellite u205-s5067 laptop. I want to clean/replace my fan.


Taking apart a laptop to change the fan is a relatively simple task. Just keep track of where all the screws go and follow these steps:

1. Shutdown the laptop and remove the AC adapter. Disconnect any devices, such as a printer or external DVD-ROM or drive, that are attached to the laptop

2. Remove the laptop battery. Turn the laptop upside down, slide the battery release latch and then pull the battery out of the bay.

3. Unscrew the hard drive cover. Grab the hard drive tab and shift the hard drive to the left to unplug it. Lift the hard drive out of the bay.

4. Unscrew and remove the PCI memory cover, the optical drive cover, and switch cover.

5. Unscrew the two screws that hold the keyboard to the base, these are located in the middle of the rear panel. Flip the laptop over so it is right side up, open and remove the keyboard by using the keyboard release switches located above the keyboard. Next, unplug the Toshiba Satellite U205-S5067 Fan cable.

6. Close the laptop and turn it over so it is bottom up. Unscrew the display assembly screws located under the laptop screen hinges. Turn the laptop over so it is right side up. Open the laptop and unplug the display assembly cable and disconnect the wireless antenna from the display assembly. Unscrew the display assembly from the laptop base and remove.

7. Unplug the mouse pad cable. Turn the laptop over so the bottom side is up and unscrew the base screws which are located along all four sides of the laptop base. Gently remove the base of the laptop.

8. Turn the laptop over so it is right side up. Unplug the fan cable from the circuit board. Unscrew the screws holding the Toshiba Satellite U205-S5067 CPU fan assembly to the laptop. Lift the fan assembly out of the laptop.

Removing/replacing dvd rom drive


Hi Jerry
I have written down steps on how to remove the DVD-Rom drive for you.
Toshiba notebooks most screws are marked.
F4 - flat-head screw 4mm long
B6 - button-head screw 6mm long
F16 - flat-head screw 16mm long
B8 - button-head screw 8mm long

When you are taking apart a laptop you'll have to deal with lots of screws. Keep everything organized. I keep them in small cups separated easier to find and don’t get lost.
1. Remove the laptop battery
2. Carefully lift off the securing strip at the top of the keyboard.
3. Remove the keyboard securing strip.
4. Remove all screws securing the laptop keyboard.
5. Disconnect the keyboard cable from the system board. Lift the edges of the connector first and then carefully disconnect the keyboard cable.
6. Remove screws securing the power switch board.
7. Disconnect the USB cable from the system board \motherboard
8. Lift off the power switch board.
9. Remove all screw from the support plate.
10. Remove the DVD drive securing screw.
11. Slide the DVD drive to the right and remove it.
12. Slide in the new DVD drive and follow this backwards.

Hope this helps it is not hard just have to take time an becareful when removing the securing strip at the top of the keyboard to get to screws.

Any questions I will be glad to help answer for you.
