[!]Vivante SE: fixing loose AC connector.
[-]Keep in mind that you are operating at Your Own Risk !
1.Take all the screws out from the bottom.
2. Remove the keyboard  (see notes below).
3. Let the screen open up, until it lays on the table, you might want to put a book underneath it.
4. We have to completely remove the screen,  so look at the two sides where the screen is attached to the laptop. Do you see that word VIVANTE on the bottom of the screen? Just to the left there is this cap that you can just slide to the left. You might want to use to force here. Also, do the same to the cap on the right side of the screen.
5. Underneath these caps you see four (clear) screws. Just take them out! The screen will come of.
6. The place where you took the keyboard from there is (was) a metal HEAT plate. Underneath it (you have to remove it) you see the connectors from the screen, take these out too!
7. The keyboard and touchpad are both connected to the laptop with a connector. Pull the connector, NOT the cable! When you pull it just a little, the cable comes loose. Carefully!
8. Remove the harddrive, by pulling it towards you. That's easy.
9. Now the FUN PART!!! Take all the screws out that you can see. Memorize where you got them from.
10. When this is done, you can go ahead by take the top of the laptop. You might want to use some force again. I took a knife and pushed at all sides of the laptop.
11. Just look closely how the both parts are connected.
12. Finished? drink some coffee, walk the dog or something ;-)
13. The motherboard is only attached to the bottom with 4 screws if I remember correctly.
14. Now, the place where the harddrive use to be is somewhat relentless to let go, so use the knife to detach the motherboard from the bottom plate.
15. Okay, I think by now the board is completely loose, and you can take a
look at the connector.
16. My connector got loose on the GROUND-side of it. Just some cracks in the
solder, nothing big.
17. Solder the joints....

And then re-assemble ;-) 

[!]Vivante SE: Replacing/adjusting keyboard.
[-]Keyboard is attached to the board via ribbon cable, and the connector is kind of loose i.e. if it's shifted slightly you may experience some faults usually with side keys. 
To get aquainted with your keyboard you may gently slide to the left the plastic lid (the one with a small holes in the upper part of the keyboard) and curiously but GENTLY lift and slide the keyboard plate but DO NOT PULL IT OUT since the flat wire connector is kind of loose).  The flat wire goes in the bottom of the keyboard plate, so you should be able to keep the keyboard plate standing upright on its bottom edge right in place without extracting the flat wire. Then you will see how it's connected to the board.
IF YOU'RE NOT SURE IN YOUR HANDS DON'T DO IT BY YOURSELF, because if you extract the flat wire you disconnect your keyboard. Yes, it's so easy beacuse it's meant to be so in order to change keyboard quickly, but if you don't have such experience you will spend some time connecting it back. In your case you want to just press it  LIGHTLY down holding the wire close to the connector on board.
After that close everything in opposite order. 
 

|disassemble:Vivante XL|

[!]Below are the steps you can follow to locate your CMOS battery. Keep in mind that you are operating at Your Own Risk if you follow these steps. Before doing so, make sure you look in the RAM compartment on the bottom of your Vivante XL to see if your CMOS battery can be seen. 
[-]First, remove the speaker assembly:
1. Remove the keyboard.
2. Using something like an Exacto knife, cut a small square in the "Vivante XL" label found on the speaker cover. Cut the square under the "X". The grill covering the speakers already has a small hole there.
3. Using a philips screwdriver, loosen the screw found at the bottom of the newly formed hole.
4. There is a black piece coming from the center of speaker assembly with a screw holding it in place. Remove that screw.
5. The speaker assembly should now lift up.

The CMOS battery is at the top near the screen above the F9 and F10 keys.
Unfortunately there are a lot of screws that have to be removed before that plastic can be lifted. Keep good track of the screws as you remove them.

1. Unplug the two connectors that go to the screen.
2. Remove the screen's hinge covers.
3. Remove the hinge screws and set the screen to the side.
4. Go around the outside of the case and start removing screws starting with the two that you uncovered by removing the screen. The top part of the case is easy to remove. There are a few places where it snaps into place but it is still easy to remove. If you are having a hard time getting it to pop off, look for more screws to remove.

Once the top of the case is off, the CMOS battery is standing upright near the top left corner of the floppy drive (if you have one).

|disassemble:Vibrant |

[!]Vibrant: Reseating modem.
[-]If the BIOS setting is set to modem, but the modem fails diagnostics (and you feel brave), you can try re-seating the modem. All it entails is sliding the top plastic piece above the keyboard to the right and removing it. Carefully lift up the keyboard, becareful not to pull out the keyboard ribbon cable. You should see a metal plate with 2 or 3 screws in it. Remove the screws. Once the place is removed, you should see the modem on the left side. It looks like a green circuit board about 2" x 2". It should have a black sponge-like pad on the right side. Push down on the pad.
If you feel it move down a little, then this was the problem. Put everything back together and you should be ok.
