How much wattage do modern displays use?

[Billy_Mays]

Im looking to do a DIY project for a portable PC, I got a cheap laptop that has a 65w wall adapter, so I was wondering what display I can use that are relatively small and have both VGA and HDMI (HDMI is for consoles so I can switch between playing games and having a desktop), I do have a 300gb HDD but I need to get a new logic board for it but Im not sure how much the logic board's gonna cost me cause I'd like to do this on a $150 CAD budget, the HDD's pcb model number is JUE234N82434, or thats what I can see because they're is a scratch preventing me to see what is there, the HDD model number is HD321HJ made by Samsung. So what can I do to make this project possible?

Linus has used USB-powered displays in the past for his DIY Project WhatevertheheckRazernamedtheirtriplescreenlaptop, although those were pretty expensive(350 USD).

Umm, yes it did. You just needed special cables. As for the hard drive, replacing the PCB is not usually a good idea. Every drive has it's own particular ways of doing something. Just get a new drive.

eitherway you wanna do the project or you dont, you gonna need a new drive anyhow you wont be able to fix this.

also while we are at it since you want to make a portable PC you should get an SSD simply because vibrations dont hurt them.

 

for 150 bucks you will never ever be able to purchase the parts you need and have anything thats usable maybe a raspberry pi and some small display but thats it with the budget.

The laptop parts are from 2012 so I dont want to waste tons of money on it
