Re: Laptop AC Adapters - 65W vs 90W
What laptop and what battery do you have?
Did you order this or did Dell recommend it?They have at least one 90 watt unit: 90 watt travel adaptor<ADMIN NOTE: Broken link has been removed / replaced from this post by Dell>
The 65 watt unit will do no harm. The battery will not recharge as fast, and the CPU might throttle down. Best to use with the battery fully charged or removed if not charged.
