Why do you want to open it? I suggest that you blow compressed air (available in cans in computer shops) through the vents. It will clean as well.

Lapotop is not charging but showing that charging is continue

This sounds like your battery is consumed. Like all rechargeable battery's they have a certain lifespan. Its also worth taking the battery out and check the contact on the battery.

Blue screen error plus blank start up screens but the start up sound can be heard.

Have you changed any BIOS settings? I would open your BIOS menu and make sure it is set to "AHCI"

My DS Lite has a big blob of water in the touch screen because I cleaned it and used too much and it sunk it. It's bigger today than it was last night. I turned it on and the thing barely responds to...

Good day mw02261,

I apologize for the inconvenience this has caused you. I do own an NDS Lite as well but I do not use any kind of liquid to clean it. I just use a soft cloth that you normally use for cleaning eyeglasses. With regards with your problem, do you have any idea how to open up the case of a DS Lite? If you haven't done this before and your console is still within warranty I do advise that you seek assistance from someone who knows how to do it.

If you are a DIY'er, here is a good YouTube video on how to open it up. You might need to use precision screwdrivers/tri-wing to open up the casing.

2003 kia sedona door wont open from inside or out, latch is broken. how can i open the door to fix this?

You'd have to remove the door panel. Probably impossible while the door is closed, may have to cut it. Ask a bodyshop or dealer for advice.
