Dell D620 not running on AC power

\015 I have had a problem with my dell D620 giving me the error message that "the power adapter type cannot be determined" for about a month now. However, it has still been charging fine, and i assumed it was some quirk of the dell quickset power management software, since the same adapter worked fine with my father's D520. However, I turned on the laptop about two days ago, and it would no longer charge. Not normally a big problem since I knew the battery was getting towards the end of its life, but for some reason the computer is not running on AC power. It will not even register that the adapter is plugged in. I tried the adapter to my father's D520 (same type of 65W dell adapter), but it did not fix the problem. I was just able to back up my files onto an external drive before the low battery power shut the laptop down. So, I am unsure of how to procede...should I purchase a new battery and hope it is some quirk of Dell's software that is causing this? I have no idea where to go from here. Any suggestions would be greatly appreciated.\015

Answers :

By the description of your PC and of the replacement board, it should work. But I would suggest some further checking. This is not an easy way to diagnose a repair. If you have the Service Tag(on a white label on the bottom) go to www.support.dell.com, check the warranty status, I know it's out but it will get you to where you can view the original config of your laptop. Check the list for the MB specs and compare that to the one you found online. If that checks out, I'd go for it. Another option would be to try and find a used laptop online. I've seen some newer ones on ebay that were reasonable.

Anyway, keep me posted on how it goes.

I'm afraid that Power Controller IC is went bad/fried.
It didn't sense correct DC voltage from adapter and were giving you those messages.
Best case scenario is Cold Solder and resoldering of IC will help.
