Where can I get a power supply?

You should be able to buy CF cards at just about any camera, department, electronics, or office-supply store. Some drugstores and supermarkets carry them as well.

cheaper to buy a new camera, I got mine for 100 bucks from Buy.com, you wont be able to replace the lcd screen without sending it in

Open the Notebook, and remove the System RAM slowly and clean it legs with a white paper and place it again and check,if the problem still persists insert the RAM in different Slot.

REPLACE THE BATTERY.

There is a service that specializes on small consumer level cameras like that : Camera Repair NYC Even if you can't find the screen on their website - contact them and they'll find it for you.

Hi! It appears that possibly your hrad drive isn't set properly in the caddy? with the laptop powered down and disconnected locate the hard drive cover pop out the two locating screws and carefully move the caddy/hard drive BEWARE as the drive has fragile pins at the opposite end where you opened, hopefully little sliding pressure should remove. Check the retaining screws around the caddy (You'll need a small torx/philips screw driver for this) if all tight replace gently.
If you are uncertain I would recommend a technician check it for you.
Good Luck!

Check these settings first. In a clear spot on the screen where no icons are, right click and go to properties, box opens and at top should list from R to L, themes-desktop-screensaver-appearance-advanced. click on screensaver, close to bottom click on power, another box should open, click on power schemes, make sure it's set to portable/laptop, and at bottom make sure settings for plugged in are are set to never. If it's not that then you have a bad power supply cord, or a bad power supply unit in laptop. If it's new and under warranty take it in and have replaced if not warrantied then will cost you about 100-150, just a guess!! hope this helps. But it sounds like the supply cord making the beeping noise might be bad. Make sure it's plugged all the way in as well.

take battery out, plug in and turn on. does it turn on? any lights on the laptop on?
