Dell PA-10 ac adapter center pin

Christopher Muto typed on Mon, 04 Jan 2010 16:54:46 -0500: ... a simple test of this condition is jiggle the plug on the computer end while it is inserted into the laptop and watch to see if it switches between battery and ac power. Well that is a tip-off for sure. But if it doesn't, it doesn't mean it isn't the jack itself or the solder connections to the board. As sometimes the jack can break (and it is still can be solid as a rock) or a solder connection or something... and no amount of wiggling will make it work for some of them. -- Bill Gateway MX6124 ('06 era) 2 of 3 - Windows XP SP3 |

Chris:
Can you elaborate. Lately, my Inspiron does switch from battery to AC when I jiggle the chord a bit. What does that indicate? Is it easy to fix? Mel "Christopher Muto" wrote in message t... phoenix wrote: My PA10 works intermittently. Anyone managed to repair it or do I need to buy a replacement? are you sure the problem is the adapter and not the computer? it is a common and unfortunate problem with many model laptops that the connector in the computer becomes loose and so has poor contact with the system board. a simple test of this condition is jiggle the plug on the computer end while it is inserted into the laptop and watch to see if it switches between battery and ac power. this should be covered under warranty or there are many shops that will re solder the ac jack back on the system board for a flat fee. depending on the age of the system it may not be worth the expense. having said that, genuine dell pa10 adapters can be had from ebay for about $20 delivered. clone "for dell" adapters can be had on ebay for close to $10 delivered but they are junk and will not be as durable or long lasting. |

For those that use their laptops on AC alone, I figure this would be a gold mine for somebody. Even adding a power regulator inside (since the AC adapter voltage is higher than the battery) shouldn't be too costly. After all, you can buy AC adapters for 10 bucks or less on eBay. Another solution is if your laptop can handle a docking station. Well there you go. No power jack required. grin -- Bill Gateway M465e ('06 era) - Windows XP SP2 |

Thanks Chris.
So far, it has not been a problem. But I suspect it will get worse over time. I don't think it is the chord. This Inspiron 2200 (much maligned by many on the newsgroup) has worked flawlessly for me for about 7 years. When it gets worse, I'll buy a new laptop. I also have an Acer netbook which I like a lot.

Actually I've found that the power supply's cord/wire to the computer is the *most common* problem I've seen. Not just at the connection to the computer, but especially at the junction where the wire enters the power supply itself. If the problem is at the end connector or the jack, the customers usually had issues with putting the computer away (in a laptop bag, etc.) with the power supply still connected. (I know, Duh!) If the problem is at the junction of the wire and the PS, it's usually from a "road warrior" that travels a lot and pulls the cord tight when wrapping the cord around the PS when packing it up. I always tell folks to leave a 1-2 inch loose loop in the cord so that you don't bend the cord at the junction to the PS. If any of the 3 wires in the cord get damaged from repetitive bending, you've got to repair or replace the PS. Luckily, it's pretty easy to pop open a Dell Laptop Power Supply and unsolder the three wires and cut off about 6 inches of the "damaged" section, use heat shrink tubing to insulate the 3 wires properly, re-solder the wires and glue the PS back together. But you've got to remember to test ALL the wires in the cord for shorts to each other or open connections to the plug. Sometimes I've had to cut down some cords to 1/2 their length or less. Some were totally trashed. I have more PS boxes without wires than I expected. Found a place that sells these wires for $15 each including shipping (http://dcplug.net/dell.html), but it's higher than I'd like to pay. They should be about $5 or less each plus shipping ($3-$5). I don't have a video showing you how to do it, but it's not that hard for someone experienced with a soldering iron. That $15 cord (above) would make it very easy for most self repair folks to do. Good luck! |

Dell PA-10 ac adapter center pin
Being as I have done laptop dis assembly for jack replacement for years and years now, I have personally seen hundreds of examples of faulty 1-wire \ maxim chip issues.. Anyhow, a close friend came to me with a dell latitude D620 that exhibited all the telltale signs of a bad 1-wire chip; ie: it would recognize my PA-10 adapter (and consequently charge AOK) however his would come up as unknown and not provide a charge. SOOOOOO I embarked on the 1-wire id chip adventure as so many of you also have. What I did hehe was post an ad on craigslist, looking for free\cheap dead or alive PA-10\PA-12 adapters... And got literally hundreds of hits. So yea, next step of course would be mass dis assembly! When done with all of the adapters, I had 15 3pin chips, and another 8 or 10 8pin chips. Now from what I've found, the 3pin units can be wired up directly without any protective circuit and are quite reliable, where as the 8pin packages are less so. Anyhow, I've been making both adapter plugs with the 1-wire chip hardwired in them, that amazingly work with just about *any* adapter... All the way up to 130w HP units. And yes, they even display in the bios as 130w. Another neat trick is hard wiring them into the Dxxx compatible docking stations. Anyhow, I'll post some picks here in a day or two. |
