Dell Latitude D620 AC Power Adapter
Dell Latitude D620 AC Power Adapter Fault
I have a Dell Latitude D620 laptop. The power adaptor is dell’s standard one, with the large white tipped connection to the laptop. The power brick itself comes with a strap, which is useful for keeping the cord tidy when carrying it around. A lot better than stuffing the cord into a bag and having to spend ages untangling it next time it’s taken out.
During the last week, it seems Dell Latitude D620 AC Adapter that I purchased 2 years ago has developed a fault meaning that the AC adapter is not detected by the laptop. It still charges and powers the laptop fine however on every boot it makes a very loud beep and requires you to strike F1 to ignore the warning. In addition, the performance of the laptop is reduced to a minimun.
Then I checked the adapter by the following steps:
1: The LED on the adapter connector doesn't light up when attached to the computer.
2: The adapter only charges the computer intermittently.
3: A separation of the white insulation on the adapter (also known as strain relief)
After looking around, it seems the AC adaptor contains a proprietary 1-wire device that transmits a serial number to the laptop. This is meant to prevent you from using 3rd Party adapters, only using Dell’s own adapters. However, the chip and communications are very prone to breakage, which is what seems to have happened in my case. This is not an isolated incident.
Unfortunately, it is not in the warranty time, so I need to buy a new one, then I seached it on the internet, and find a very good one at www.usadapter.com, which sell many kinds of ac adapters, such as Acer AL1714 LCD adapter(AC100-
