Have a Dell Inspiron 1525 with a Battery Charging Issue? Let’s talk.
As you may or may not know, I run a business out of my home called Tech Guy Consulting. I’ve been doing this since I was 17 and have developed a pretty decent customer base in my home area. One of my loyal customers brought me their 2 year old Dell Inspiron 1525 tonight with a handful of issues, but only one stood out to me as “outside the norm.” After a factory restore, the computer power management icon (the little picture of a battery with a power cord over it –in the bottom right hand of the screen) show that the power supply is “plugged in not charging.” So I eliminated all software issues right off the bat:
-Updated the bios
-Updated all drivers (not necessary but worth a shot)
-Uninstalled/Reinstalled Microsoft ACPI Compliant
-NOTE: this is on a fresh install from a Dell factory image
And then a little hardware troubleshooting…
-Tried a working Power Adapter and Battery from another 1525 (no dice!)
-Cleaned the contact port for the power adapter
-Cleaned the contacts for the battery
-Reseated the memory
-Allowed the battery to discharge completely to 0% (I did this by removing the power adapter and booting the computer into the bios. The bios will not hibernate the computer like Windows will, so leaving it in the bios will drain the battery to the point that it will not power on your laptop)
-Tightened the screws that hold the DC Power Circuit board to the chassis
-Unplugged the adapter, removed the battery, and held down the power button for 15 seconds
After all of this, I still encountered the same error. It’s also important to know that the system bios will report the power adapter as an “unknown adapter.” My conclusion for this issue is that the Dell 1525 has either 1. A faulty DC Power Board (a circuit board in the computer that has the DC Power Jack attached to it along with the 2 USB ports next to it) or 2. A faulty motherboard.
Could I replace one or both of those parts? Certainly! However, should my customer have to sink $300 + in the repair of a computer they purchased for around $500 new? Not in my opinion. So I set off on a research tangent…what did I find you might ask?

Sorry, You'll have to keep me plugged in from now on!
1. My customers are not alone in this issue. There are THOUSANDS upon THOUSANDS of 1525 owners with this identical issue
2. There are thousands of sites and message board posts dedicated to this issue, one stating that there are over 40,000 logged complaints about the issue. Some people state that “blowing in the battery” helped, but I assure you…this solution is most likely just coincidental Here are a few of the sites I visited…
-Google Search Results for topics on this problem that are posted in Dell Forums
I could post a tremendous list of sites but we’ll pass on that idea for now. The fact is there are thousands of known complaints about this issue. So, being the junior detective that I am…I called Dell. After I spoke with one ridiculously rude foreign fellow (he had teenage girl style argument with me before transferring me in the middle of our conversation) I was sent to Tech support. However, this particular laptop is out of warranty and I was already aware of Dell’s “No Warranty? You’re S.O.L.” policy. I spoke with the technician and his supervisor, both of whom stated that “Dell has no official statements on this issue.” They did, however, offer to sell me the parts at a ridiculous price, so I could keep my customers happy. At the end of the conversation, all I got was “no warranty no help.”
So basically my customer is forced to pay the fee, use their laptop on the power adapter for all eternity.
Here’s the reason I took the time to write this article. Dell knows about this problem, with all of the complaints there is NO WAY they don’t know. However if there is no “big public stink” made, they will never rectify the issue and compensate the customers who, in my humble opinion, have every right to feel nothing but ripped off. So here’s my proposition to you loyal 1525 owners: Post a comment in this blog post stating your model number, when you purchased, the fact that your having the “plugged in not charging” issue, and anything else you want to rant about concerning this issue. In exchange, for every 100 comments this blog post receives I will send an email and put in a call to Dell Customer Care referring them to this post. I will also post links on Ripoff Reports and the Consumerist. My goal is to help all of you 1525 owners (my wife has this laptop, although she doesn’t have this problem) find satisfaction. Whether that be through free replacement parts or repairs from Dell, or..dreaming a little dream here, replacement laptops from Dell. Do not remain silent! Let’s tell the big wigs at Dell that we will not be pushed around!
A few requests when posting a comment…
Please don’t post any proposed solutions, as I’ve already exhausted them all. The idea is that we be straight to the point and that these comments all remain relevant.
Inspiron 1525 bought in November 2008, in Germany, now also with this battery charging problem :-’(.
18 month old 1525 – worst purchase I have ever made (UK).
Plugged in – not charging despite trying all the fixes I can find on the web
Thanks for the comments guys. Feel free to link this post on dell message boards so we can get the word out!
Dell 1525. Plug in , not charging. Bought it a year ago. No help from Dell
Hey Joe, Sorry for your troubles! Hopefully Dell will fix this problem soon! Please feel free to spread this post around! Hopefully we can gain enough support for the cause!
Inspiron 1525, plugin not charging issue. Baught it in year ago.
16 months old Dell Inspiron 1525 with “Plugged in, Not Charging” problem. Fixed charger and bought a new battery. Still not charging. Very annoying! This is a must recall laptop.
Sorry to hear about your troubles CAnongfu, at least you know you’re not the only one! Feel free to link this post wherever you see others having troubles, the idea is to consolidate everyone with this problem into one area of the web so we can easily show Dell that they have a problem!
Same problem. I have a degree in electronic engineering and solid state physics and I completely agree with the analysis here.
Inspiron 1525 bought in November 2008, in New Mexico, now also with this battery charging problem :-’(.
Same problem here.
Same problem here,bought Dell1525 in September 2008 in Qatar and now this “plug in,not charging” problem came
Same here. Thanks for your investigation. Saved me buying unnecessary gear.
Hey guys! It looks like the comments are racking up, and the momentum is picking up on traffic to this post. Hopefully we’ll start making a big enough stink about this problem and Dell will notice!
Have the same problem. Started maybe six months after I purchased the computer, Inspiron 1525. Computer is about 20 months old now.
Having used many Dell products I bought a used Inspiron1525 about 2 years old. The person I bought it from said the battery was bad but a new battery cost was reflected in the price. This was before I knew about the unknown adapter problem. In theory, the smart ID of the power adapter for power management seems like a good idea, Dell’s implementation has some issues though. (Dell holds a patent on this. Do a search on ds2502.) I guess for now I’m stuck with a power cord bound laptop and a new opinion about Dell.
Correction to my last comment. The patent was found under a search on ds2501 not ds2502. The patent number is 7243246.
Purchased 1525 in 2008 online from Dell, same plugged in, not charging message. Bought one new battery and three new chargers, all from Dell at the advice of Dell Tech support while under warranty.
Cannot replicate actions, but I had 20 minutes of normal function following BIOS update/frustrated banging on case.
Just how many consumers does it take to start a suit against Dell? I think 40 Thousand logged complaints WORLDWIDE is a good start!
I bought my inspiron about 2 years ago and have replaced the charger 4 times. The costs are starting to rack up and Dell needs to do something about this problem.
Purchased my 1525 in September 2008. Just replaced the noisy faulty fan (another Dell Problem), and now getting the dreaded message, plugged in but not charging.
I purchased dell 1525 in March 2008, from bangalore. Started facing the same problem – battery stays at 75%
Looking at the responses i feel that dell is going to wash their hands…I just regret my decision to choose dell.
Hey guys, just wanted to let you know that I haven’t forgotten this post! Keep the comments coming and tell your friends! We’ll let Dell know about this soon enough!

Dell 1525 Purchased a few years ago. Plugged in but not charging. Works sometimes by wiggling adapter ect. Probably going to end up buying a new board for $20 off eBay.
‘Plugged in, not charging’ is the bane of my life. What is the point in a laptop if it has to remain plugged in? Not the first issue I’ve had with the 1525. And not the first that was also troubling many other 1525 owners. I’ve had mine for a little over a year. Out of warranty and don’t know what to do.
Dell Inspiron 1525 bought in 2008 online. Same problem as everyone else; plugged in not charging! By the way, do you think changing the DC Power Board will solve the issue? You can get one fairly cheap at ebay.
Purchased Dell Inspiron 1525 in from Best Buy in September 2008 for my granddaughter. Got the unknown adapter and no charge message. Now nither work, adapter or battery. Dell shame on you!!!!! She needs this laptop for college. I always promoted dell via word of mouth, now I say “Do not buy a Dell, go with an HP or even a cheap unknown, just do not buy a Dell!!
