The SPEAKER bar has two fingers on it, you slide out the speaker, I do not remember to slide it to the left or to the right, also for release tab to allow you to slide the speaker out.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Why my screen turns black or goes dim?

A problem is loose supression coils by falling or other components that are be heavy for the print because of the thin solderings there can be a loosecomponent or printed circuit break sometimes its not easy to find or see , you must measure to most primary components on the print with some weight , Similar it comes up with battery chargers also often happens that due to the weight is usually the small interference suppression beads and some heavier components have a too small a solder surface making them with some ease to a small fall directly and with the soldering completely break out of the printing circuit without you see something

The computer screen is totally black

If your laptop is an older one, there is the possibility that the fluorescent backlight has burned out. After it boots up, look very hard at the screen, even altering your view to gaze at it from a slight angle. You may just be able to see the screen images in outline. Most people don't understand the the LCD screen itself is not illuminated, it is backlit very much like an old-time slide projector. You could get the unit serviced, but it would almost be cheaper to buy a new laptop. Get one with LED backlighting. It will last longer.

My HP Dv 6000 Laptop Battery suddenly stopped working with out any gradual symptoms . Can some body explain the possibility ?

Not trying to be too technical but lithium ion batteries last longer than Ni Cad.
Ni Cad have a memory effect and if one charges them before they are totally flat, a portion of what was left is lost and a gradual decline takes place.
With Lithium Ion, they have characteristics similar to lead acid cells and as such tend to grow "fingers" across the cells stopping the chemical reaction and one day, usually after another of the far too many charges, the cell collapses.
Hope that explains it.
