Battery wont change
A problem is just like a mountain. You don't jump over the mountain, you climb it in steps, one step at a time.
1.How old is the battery? 1 to 2 years old, you can expect it to be at the end of it's Life Cycle. Batteries are rated in so many hours of usage.
Best bet is to let the battery charge 24 hours, then try it.
Would be nice if you someone else that has an Inspiron 1525, and they would try to charge your battery. If it doesn't charge up, you would know it's the battery. If it does charge up you can move on down the charging system, to try to find the problem.
2.AC adapter, (Charger) If you have a multimeter, set it to the 50 volt DC scale.
Laptop and desktop computers use DC current. (Direct Current) Your house, for example, uses AC current, (Alternating Current)
AC is converted to DC by the AC adapter, (Charger)
An example of DC current are flashlight batteries, and your laptop battery.
DC current has a Positive pole, and a Negative pole.
The center pin of the plug of your AC adapter is the Positive pole. Any of the four outside pins on the plug, are Negative.
The Red, (Positive), probe of the multimeter goes to the center pin. The Black, (Negative), probe goes to any of the outside four pins on that plug.
Example of a DC Power Jack, for the Dell Inspiron 1500 Series of laptops, 1525 and 1526, (This is the jack inside your laptop, where you plug the AC adapter into),
3.It may be that DC Power Jack itself is bad, or one of the solder connections is cracked. It's hard to see it clearly on the link I provided, (So I Right-clicked on it, Save Image As, and put it right in my My Pictures folder. Then I magnified it), but in the photo you will see some metal pins sticking out of the rectangular body.
The metal pins are sticking up. In reality those pins go down, when the jack is mounted on the motherboard. They go through the motherboard, via holes, and are soldered on the other side.
It is these solder joints that may crack, is what I'm referring to.
Solution to 1?
Obviously buy a new battery.
Solution to 2?
If your multimeter findings show lower voltage than needed, it's time to buy a new AC adapter. They have generic ones that can be used on a variety of laptops. The voltage will be stated on the top of the AC adapter.
That's 19.2 Volts at 1 AMP.
It may just be the plug end on the AC adapter itself. The plug end that goes into the DC Power Jack, on your Inspiron laptop.
Solution to 3?
Unless you are a skilled Electronics Technician, and have Excellent de-soldering/soldering skills, I advise taking it to a computer repair shop. It may not just be cracked solder joints. The DC Power Jack may need to be replaced. Maybe the motherboard is one of a bad design, and where the DC Power Jack attaches to it, has cracked.
