how long are the cords?

All together, the cord is 10 feet long.

Is this compatible with Lenovo Chrome?

I do not think so. It is a spare blue tip charger for HP.

I have a hewlett-packard laptop computer model number 15 - d w l xxx do i need a blue tip charger and if so what wattage?

First of all your laptop must still have the original one that came with it at purchase. If so all that information should be on the charging unit attached to the cord. It should tell you the voltage and wattage. If you do have the original, just look at the part that connects to the laptop and see if it has a blue tip. One other option is to plug in the information you have for your laptop, the one you mentioned in the search bar here on amazon and it should give you a list of power cords for your laptop. Hope this helps.
