Review on Genuine HA45NM140 Laptop Adapter Charger by Raquel Syafitri

If the adapter is not genuine Dell, it cannot be visually identified. It also works exactly as it should. Dell puts a chip in their power supplies that does nothing but verify that the adapter is genuine Dell. Unfortunately, if the 25-cent chip in a PS fails, the computer's processor will slow down and the battery will not charge. My original adapter (8 months old) put out the required 19V, but the computer's BIOS wouldn't allow the battery to charge. This is a really lousy way for Dell to make money and this will be my last Dell product. This adapter worked great as soon as I plugged it in. Fingers crossed it lasts longer than the first. I will update if it doesn't work.
