I bought a Inspiron 1525 in March 2008. As of today the battery is not charging. I called Dell and they told me that I needed a new battery. After spending nearly $135 for a new battery, I am still having the same issue. Unfortunately my laptop is out of warranty. I have read the various forums on here to find a solution, but still nothing. It seems this is a pretty regular issue with the Inspiron 1525 and other Dell laptops. Can Dell come out and FINALLY say what the solution is? Why is it so hard for them to say what the problem is. It's pretty sad I spent $135 for battery after being told that was the solution. Can anyone help me? I've updated the BIOS, I blew into both recepticals, and yes, even tried a new battery.
The mainboard? I believe my adapter is working fine. When I plug it in to my laptop it works fine. You would think Dell would recall the inspiron 1525 and other laptops, being that this is a common issue. If the mainboard needs to be replaced then I would think that would be quite expensive. Better off to go buy a new one. Probably will not be buying a Dell though. I've had a HP laptop for almost 5 years now and had no issues.
I haven't seen any statistical evidence that Dells are more prone to power failures than others - in fact, the HP you speak highly of is the one that has a much worse reliability record:
The BIOS update won't work unless your battery is at least 10% charge; mine is zero. Can't charge because the BIOS needs to be upgraded and I can't apply the BIOS because the battery is 0% charge.
I purchased 2 of the 1525 laptops at the same time in November 2008; one for a friend. Oddly enough, they have different versions of the AC adapter. The other one works fine on my laptop and charged the battery so I could apply the new BIOS. After applying it did a reboot and when I logged in and checked the icon, it still said "plugged in, not charging". I said 'Oh well, so much for that' and let it sit while I watched TV. I came back later and it said 100% charged. I let it run on just the battery for a while, then plugged the adapter in again. "Battery level 97%, charging". So it seems to be charging again. We'll see how long it lasts.
After we did the BIOS upgrade the charger worked steady for about a couple of weeks. Now it works intermittently. My son gets mad when the battery goes to zero because he has to shut down if he wants to move anywhere. Other times the battery will charge for days at a time.
His friend has an identical laptop; we purchased them together. I can put my son's battery in the other laptop and it will charge. If I put my son's AC adapter on the other laptop it won't charge at all. If I put the other laptop battery in my son's with the other charger, it works. I don't see how it can be the mother board but that's what everyone says. I think it's a combination of things because Dell buys parts from many different suppliers. I'd replace the AC adapter but others that have done this say it helps for only a few weeks then the problem returns.
I won't replace the mother board because it's too costly and too much work. Because of all these problems I won't replace this 1525 with another Dell. I'll be looking at HP for my next one and turn this one into a desktop until something else fails.
It sounds more like you have a faulty AC adapter - though it could be the power jack ( which is on a $100 power board, not the mainboard).
Beware before buying HP- their hardware is the least reliable out there and their support is bottom of the barrel.
