How to Check Laptop Ac Adapter Fault and Buy a Right Acer SADP-65KB (REV.D) AC Adapter



I have a acer laptop with Acer SADP-65KB (REV.D) AC Adapter. The power adaptor is acer’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 Acer SADP-65KB (REV.D) 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)
