Used to work fine, but when on battery power the battery light glimmers on and off weakly in green, but the charging light does not light up. Tried new battery but does make difference. Is there something wrong at motherboard end?

There is a small IC that Dell solders into their power supply as well as their batteries. When this parts fails you will have the type of problem you are having now. If you do a search on the web you will find a large number o sites that discuss this. Unfortunately there is no fix other than replacing your power supply. I had to do the same thing myself for the Dell laptop I use.
I had the same problem with a D620 at work. The laptop worked fine but the lights kept flashing on the front. I tried a few different things but it ended up being a bad battery. If the battery is less than a year old Dell will replace for free. Otherwise, you'll have to purchase a new battery.
Laptops are notorious for having the adapter plug come loose from the motherboard although, most laptops will power off of the battery if this happens (if the battery has a good charge). Some laptops have a DC power board that can burn out. Or in some cases, It can be the power button bar. If you are not comfortable trying to repair it yourself, I suggest taking it to a reputable repair shop but it will probably cost you quite a bit to get it fixed. If you know someone who does this type of repair you might check with them.
