Even with new batteries, my camery says it needs batteries

Sounds like the battery is either very very low or dead. Try plugging in the charger for a few minutes and then starting it WHILE LEAVING THE CHARGER PLUGGED IN If it works, try to charge battery without using it for 6-8 hrs. If it will not take a charge you need a new battery.

Check the timer configuration .

Need to reinstall windows, insert your windows disk and boot from it.
If that does not work buy/get a new AC adapter and/or battery.
if that gets you no where open the case area around the fan use a can of compressed air n blow it all out.

Try to turn off the laptop
Remove cables and battery on the pc
Press and hold the power button for 5 seconds

Check if the PC still shuts down. If it is, try to connect the power cable without the battery. If it turns on, call your pc manufacturer to replace the battery....

Check if you will be able to shut down your pc using the operating system..

sounds like the starter, you can try tapping it with an insulated tool 2-5 times before you try starting it

Try lithium batteries. Sometimes regular batteries even when new cannot run a digital camera.

I have a ViviCam 8400 and have the same problem UNLESS I buy Duracell Power Pix or Energizer Titanium batteries. These cost more than the regular grade AA batteries, but when I used brand new regular batteries, the camera would turn on for 2 seconds then turn right off. Titanium or Power Pix batteries make the camera work fine. And, because they are made for digital media, they do allow you to use the camera for longer periods of time.

Be sure to charge for AT LEAST 14 hours on the new battery, even if the charger light goes out - it's still trickle charging. It's normal for most camcorders to auto-shut off after 5 minutes, if it's not recording. But if your batt light comes on, the problem is probably with the battery.

Here is a fix I got from Sandisk support: Let's try this: take the battery out of the player and wait for a full 5 minutes. While the battery is out, please hold the power-on button for 10 seconds. After that, connect it to your computer (without the battery). Does it work when it's connected to the computer? Regardless of that result, disconnect it from the computer, then put a brand new alkaline battery back in, and see if it will turn on. Now, another thing I found that worked once, was to remove the battery, hold the power button for 5 seconds, then replace battery. The unit powered up after that.
