To increase the battery operating timeline you can do a number of things. These usually include dimming the screen, adjusting the power setting to turn the screen off after 10 minutes and stop the hard drive from spinning when idle after a period of time too.

Results will vary from laptop to laptop and depends if the quoted 6 hours 30 minutes time frame is an actual recorded time of usage off ac or based on windows assumption and estimation.

Windows power management can only tell you the time in which battery power is maintainable for based on the consumption rate at the time. With this being said start up and playing games will utilise more power that say word processing after the initial startup has cooled down.

Some laptops can be operated without the battery however there are an increasing number of laptops these days being manufactured without this option. You can attempt to operate it without the battery and doing so will not damage the laptop in any way. If anything it will maintain the life expectancy of the battery.

Hi
Please remove the battery, hold on power button for about 50-60 seconds, then plug-in the charger and turn the laptop ON,
Please tell us your results
Good Luck

It can be as simple as bad caps, or worst case will be bad lamp assembly.

my suggestion to you is that you try connecting to an external monitor and see whether it works or not then we can proceed basing on your feedback....please,let us know the outcome

Usually indicates a problem with the motherboard.

Try removing the battery, reseatting the memory.

If that doesnt' work remove the dvd-rom and also the hard drive.

We're just trying to get a display at this point ;)

Let me know what happens.

You have a defective CCD imager - the part of the lens that receives the image. Will need to be replaced.

The filename (e.g. DSC0012.jpg) shows the image number, the filespec shows the date and time recorded. Most software will give you document info about resolution of the image. I wouldn't worry about what the battery status was when the shot was taken or how many other images were on the Mstick. I guess I'm not sure what you need.
