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.

How to reset bios on compaq v2000 laptop


Remove A Cmos Battery From A Compaq V2000 Laptop

The Complementary Metal-Oxide Semiconductor (CMOS) in a computer is responsible for storing hardware settings and time on your computer. The CMOS is powered by a small battery and is able to store information whether your computer is turned on or off. While the standard CMOS battery lasts for up to ten years, you may need to replace your CMOS sooner than that. If you password your BIOS and forget the password or need to reset your configuration back to the default, you can remove the CMOS and re-insert or replace it.

Instructions
1. Unplug the computer from the wall outlet and unplug the AC adapter from the computer.

2. Turn your Compaq Presario V2000 face down and slide the battery release latch to the left to disengage the battery from its position. Remove the battery.

3. Unscrew the screws over the hard drive cover, which is located in the lower right corner of the laptop if your laptop is placed with the battery away from you. Lift the hard drive tab, located on the left side of the hard drive, and slide the hard drive to the left to remove it from the computer.

4. Unscrew the single screw located directly under the optical CD/DVD drive. Insert a very thin item, such as a paper clip or pin, into the hole located on the optical drive to open it. Slide your optical drive out of its tray to remove it.

5. Remove the two screws located on the switch cover, which is directly under the battery. Turn the computer right-side up and open it as wide as it will go. Use a flat tipped screwdriver to lift up the switch cover that is directly above the "F1," "F5," "F11" and "Insert" keys.

6. Unscrew the four screws that hold the keyboard in place. These screws are are located in the upper right corner of the computer under the switch cover that you just removed. Lift the keyboard up and slide it forward until it rests on the palm rest. Unplug the zif connector, which is located directly above the palm rest, to disconnect the keyboard. Lift the keyboard up and out of the laptop.

7. Turn the computer upside down again and remove the memory modules by unscrewing the two screws over the memory compartment located directly below the battery slot. Unclip the two clips located on each side of the memory module to release it from its slot and slide it out of the computer.

8. Unscrew the two screws on the PCI cover directly beneath the memory module. Disconnect the two wireless antennas above the card. Spread the two clips securing the mini PCI card into place and lift the card up and out at a 45-degree angle away from you.

9. Flip the laptop back up on its right side and disconnect the display cable located in the upper left corner above the keyboard area underneath the switch cover you removed earlier. Then remove the two pieces of tape in the upper right corner that hold the wireless antenna in place. Remove the two clips located beneath the tape pieces. Unscrew the two screws on the upper left corner and the two in the upper right corner that hold the display into place. Remove the display assembly.

10. Turn the computer back upside down and remove the remaining 19 screws. Lift the base enclosure straight up out of its place.

11. Locate the CMOS battery, a small circular object, and lift it up out of its place. Leave it out for five minutes and reinsert it to reset your settings. Re-assemble the computer without the battery and plug it into the wall.

A motherboard is usually replaced for one of two reasons. You either replace a motherboard because it has gone bad, or you replace an older motherboard with a new or upgraded motherboard. In either case you will have to completely disassemble your laptop to even gain access to your motherboard. Fortunately, the Toshiba Satellite laptop can be completely disassembled even if you don't have a lot of technical knowledge.

Turn off the laptop, disconnect the power cable, remove the battery pack and disconnect any miscellaneous cables and peripheral devices. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Attach an antistatic wrist bracelet to prevent shock from static electricity. Static electricity can harm your computer's internal parts. Place the laptop face down, and remove the single Phillips-head screw attached to the hard drive cover.

How do i turn on the wireless


Hi,

Good day, you can switch on your wireless by hitting the wireless switch located in front of your laptop. The switch is located prior to the right speaker, after the bluetooth switch. You can fold your laptop to avoid confusion and then lift it up like a sandwich facing you, with taht you'll be able to see the button/switches I am referring to. Hope this help you a bit. Have a great day. By the way it will give you a pop up message saying that you have enable or turn on the wireless.

4 beeps but won't come on


4 beeps of equal lenght suggest that system timer is not working, you need to change cmos battery on your laptop. If you are game, that is how you change CMOS battery on your laptop:

1. Switch off computer, remove power cord and battery, turn computer "proper" side up, open and press power button to discharge
2. Open display in full (180 degree), there is small indent on hinge cover, close to hinge on right and left side, slide in little flat (screwdriver will do) and lift right side up, slide cover towards left and remove it, do not lift on both sides simultaneously!
3. Remove two small screws on the top of keyboard, lift keyboard slightly up and towards you, be aware that keys and tabs on keyboard are fragile and difficult to replace! Lift keyboard connector and slide the cable out. it is not really necessary to remove keyboard, but it easy to replace without keyboard being in the way.
4. Find coin battery, disconnect cable from socket by pulling it gently towards the battery. Remove cable from guides and battery from it's seat
5. Replace battery with exact same type, put it back into it's seat, guide wire through and connect it back to the board.
6. Re-connect keyboard cable, place front keyboard tabs into palm rest and screw back two back holding screws
7. slide in left side of hinge cover into place, press from left to right till it click in place.
8. Re-install battery and power cord, switch on computer, re-programe BIOS ito previous state.

This should solve your CMOS batery problem. Of course you can send your laptop to the technician but that will be no fun at all... ;-)
