HOW TO CHECK WHAT ADAPTER YOU NEED: Check the back of your LCD. You will find Input Voltage. Check if it is 12V, 19V etc. Do not worry about the amp as your LCD draws what it need. The more the amp the adapter gives the better! Attention! Please make sure the part will match your machine before bidding. We do have 12V 3A, 12V 4A and 12V 6A power adapter available.
