Compatibility Notes & Usage Tips

Before purchasing, please verify:

1. The original adapter on your laptop states “Output: 20 V 4.5 A” or equivalent.

2. Your laptop’s DC input socket accepts a 5.5 mm × 2.5 mm plug size.

3. If your laptop originally used a different plug size, voltage, or higher current (e.g., 20 V 6.75 A for 135 W units), this adapter may not be suitable.

4. While the adapter supports international voltage (100-240 V), for best performance in Bangladesh it’s recommended to use a good quality surge protector or voltage stabiliser—this helps protect both the adapter and the laptop from grid fluctuations.

5. For first-time use after purchase, allow the adapter to run for 10–15 minutes with the laptop booted, to ensure it reaches its optimal operating temperature and you verify stable behaviour.
