Repairing a Dell Notebook AC-Adapter
My Dell Notebook uses a power adapter that has an output voltage of 16V at 4.5A current. One day the adapter stopped working.
I decided to try to repair the adapter. In the past I repaired several switching power supplies of PCs and also one AC-power adapter of a Asus notebook. I found out that most of the supplies had similar defects. Often they are ease to locate and to repair.
This Instructable shows how to repair a Dell Notebook AC-Adapter but using the same principles it can work with any switching power supply.
1?Things needed AND SAFETY
First of all you need the defective power supply … The you need a screw driver. It could be phillips type or a flat blade type, depending on the power supply.In case of the Dell Notebook adapter you need a Dremel tool and a cutting disc too.To find out the dead parts you need a multimeter that contain…
2?Opening the case
The Dell Notebook AC-Adapter (Dell Inspiron E1505 AC Adapter) is not meant to be opened. The case is made of two plastic frames pressed together and melted at the contact to one piece. To take it apart you need to cut the two halfes using a Dremel tool and a cutting disc. WAIT SOME MINUTES AFTER PULLING THE POWER CHORD FOR THE CAPACITORS…
3?Examining and understanding …
Start locating the parts of the power supply. We concentrate only on a few parts. I often found out that these are the most critical parts. Most swicth mode power supplies die when being switched on. At that moment a high current flows on the primary power side. You can see that if you plug in th…
4?The Fuse
Start with the fuse. Turn you multimeter to diode test (continuity test) and put the test cables on both ends of the fuse. The multimeter should “beep” and show a very low voltage (Dell Inspiron 1501 AC Adapter). If that is the case the fuse is ok and need not be replaced. Otherwise you have to desolder the…
5?The Rectifier
Next part in the chain is the rectifier. In nearly all cases I saw til today there is a full bridge rectifier used. Here it is a flat one located near the power connector. Again use the diode test for measurement. From underneath the printed circuit board you can reach the rectifiers contacts ea…
6?The Capacitor
Now use our Multimeter in diode mode to find out if the capacitor works. Place the measuring pins on the pins of the capacitor and look at the display while doing that. As soon as you place the pins the display shows 0V. Then the voltage in the display starts growing and the display shows infini…
7?Repairing
After we found out what went wrong we can repair the power supply. If the capacitor is broken, desolder and replace it. I tried to find out if this was the only defect part and decided to do further testing before trying to buy a replacement. I did not have the capacitor that was used in the pow…

Laser pointer driver, which is better?
Anyone with experience building a laser pointer, which driver is better, DrLava's Flexdrive or this one http://cgi.ebay.com/Micro-Laser-Diode-Driver-Board-0-500mA-10mmx20mm-w-TTL_W0QQitemZ180369692918QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item29fedf18f6&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1205%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50 this one can be preset for an extra $5, so it's cheaper, but will it work just as good as DrLava's or should I spend the extra $10 and buy DrLava's?
If you can get Drlava's from a local store, do that. at leat you will be able to return it if you have to.
