Turn off the computer. Hold the Fn key and power key to boot the computer in diagnostic mode. Follow the onscreen instructions to see if you have any hardware issues. This sounds like bad sectors on the OS boot partition.

Consider NOT connecting your camera to your computer.


The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.


Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.

If you're frozen as soon as you turn it on, it's because you're turning on a huge air conditioner, not a computer. It's easy to get them mixed up, I do it all the time...

Turn your computer off.
Turn the router off.
Use an Ethernet cable to connect from one of the 'LAN' ports on the router to the network-port on your computer.

Start Internet Explorer
Type http://192.168.123.456
Press Enter

Turn the DSL modem off.

Turn the Linksys router off.

Turn your computer off.

Check that all the cables are correct & are connected:
* 2-wire or 4-wire cable between telephone wall-port and DSL modem;
* 8-wire cable between DSL modem and the WAN (or 'Internet') port on the router;
* 8-wire cable between one of the LAN ports on the router to the network-port on your computer.

Turn the DSL modem on, and wait until its blinking-lamps settles down to a repeating pattern.

Turn the router on, and wait until its blinking-lamps settles down to a repeating pattern.
Ensure that the lamp for the WAN connection is on.

Turn your computer on, and let it boot.
Ensure that the lamp for one of the LAN ports on the router lights up as the computer is starting.

After your computer has booted, your router should have assigned an IP-address to your computer.
Click Start
Click Run
Type CMD
Press Enter
Type IPCONFIG
Press Enter
You should see an IP address like '192.168.xxx.yyy' for your computer,
and a similar IP-address for your "default gateway".
If you see an IP address like '169.254.xxx.yyy', then your computer has *NOT* obtained a *valid* IP-address.

Also, your router should have obtained an IP-address from your ISP (AT&T),
and you should have Internet access -- try to access 'www.CatsThatLookLikeHitler.com' (or any other web-site).

Hello,

The charger is functioning well. There are still two possible reasons why your computer is not turning on. 1. The battery, 2. The computer itself.

What you need to do is to isolate the problem.

Here's what you can do to isolate the problem.

1. Remove the battery from the computer.
2. Turn on the computer using the cord. Remember not to put back the battery yet. Just the cable and the computer connected. If the computer turns on, then, you need to replace the battery.
3. If it still not turning on by using the cord alone. Try to wiggle the cord to check whether it's loose or not. Check if there are some signs of power on the computer. If there is a power like lights lit in the computer, then, it's the computer that's having the problem. You need to bring it to a technician if that's the situation.

Please let me know if there are any development after doing the troubleshooting above so that I can get back to you if you need my help.

Thank you for using fixya.com
