Recently, my Sony Vaio laptop stopped working. The adapter light is on but my system was not switching on. Some of my friends told me to wait for one day or two and then try switching on my PC. However it did not work, so I presented my laptop to the Sony services centre, after hearing my story they told that, this is a mother board problem and so it has to be replaced. They told that the mother board will charge u $$$$ with which you can even buy a new laptop. they returned my laptop after 3 days. I brought it home and tried switching it on and my system started working. The power percentage was shown as 72%. I was very happy to use my laptop then. I kept it on for charging for 2 to 4 hrs and then switched on the next day, the power percentage showed 71%. again the next day it came to 70% then again the next day its 69%. I feel that if i keep my PC aside without using & charging, there is a drop in 1%, but i even noticed, that if i keep on charging it without using, still there is no increase in the percentage of power.
Pls help me with this problem.

This could be a battery issue rather than a system issue.
If you can...
...borrow someone else's fully charged battery that shows ~100% on their laptop, and determine if is also shows the ~70% on your laptop? If it does, that tends to confirm their system/power-subsystem (e.g. battery charging section) problem diagnosis. Note: you may have to "tell" or "train" your laptop when you change batteries. Your manual may tell you if something like that needs to be done when you put-in a "new" battery.
Also check the status of your battery on your friend's laptop after a few charge--use--charge cycles. Perhaps even ask if they'll use your battery for a week and see how things go.
Basically, do some comparisons.
If the odd behavior follows your battery, then replace the battery. There are some battery rebuilders that will exchange your battery for one re-built with brand new internal batteries for much less than a new Sony battery.
If your battery "recovers" while it's being used in the other laptop, then it's another pointer you likely do have a system/power-subsystem problem.
Also, the "charge remaining" or "charge status" etc of ANY laptop is going to vary by a few percentage points at any given time. It's not the most accurate measurement/estimating routine, so a few % points difference from day to day isn't a problem...but a continually declining value from one day to the next, to the next, and so on over a period of say a week...after being charged likely is a problem. Check to see if the borrowed battery ALSO declines in value day-to-day over a comparable period.
edit to add:
Another thing is that some laptops battery status/condition indicators get "out of sync" from time to time. There is usually a procedure outlined in the manual on how to "re-sync" or "reset" or "re-train" the laptop to properly report the actual condition.
