My friend droped it !!!

Are you losing cooling from you reserve tank?
Are you burning oil?

TOP off the coolant tank
Make a tape mark with the day and start monitor coolant loss.

After 15 minutes of ran time.
Have a friend to monitor for white smoke.

A vehicle will a leaky (no blown yet) will destroy O2 sensor.

Have you tried pushing the reset button on the lower right bottom of the unit?

The ccd sensor must be broken, you'll probably need a new lens assembly. The repair cost will be halft of what the camera sells for. There is a service that specializes on small consumer level cameras like that : <a href=http://www.portatronics.com>Camera Repair NYC</a>

Sorry mate. Seems the drop was a bit much to much for it. You should consider replacing it, And be a bit more careful next time.

Try dropping it again. Seriously. Inside the remote there is a very small 'gyro sensor' that can get stuck in one spot, basically all you have to do is jar it loose again.
I actually had this same thing happen a while ago, I called Nintendo customer support.
I was surprised. A very pleasant lady took my call within one minute of getting through the push-button maze to get to Wii Remote troubleshooting.
I explained what the problem was and what I had tried. She then asked me to check one more thing - the Wii Sensor - which checked out. Then the conversation went something like this:
Friendly Nintendo Help Desk Lady: "Okay - I want you to take the remote, button side down and smack it into the palm of your hand two or three times."
Me: "You've got to be kidding"
Friendly Nintendo Help Desk Lady: "No sir, do it hard enough that I can hear it across the phone line but not hard enough to damage the remote"
Me: "You're sure?"
Friendly Nintendo Help Desk Lady: "Yes, sir."
So, button-side down, the funky Wii remote got smacked in the palm of my hand three times....
...and the thing worked!

Check D-links site for a firmware update. Routers do this after awhile, I have personally encountered this on sever units.

My friend droped my camera and the lens is sideways. i can look at my pictures, but when i want to take a picture it is black and says lens error. what should i do?

Take Time

get it to see the unit again and download the latest firmware.
if after that it still wont load your hard drive is toast. (did you drop it)?

Take it back to the store dont waste any more time trying to troubleshoot its probally a factory defect !!
