The first issue sounds like a bad LCD. I can help you with the second issue. You didn't mention which Windows you are installing but because of the sata controller issue I will assume you are converting from Vista to XP. Here is how you do it: You will need to slipstream the sata drivers onto the XP installation disk. You will need to download these two programs: nLite
, and CDburnerXP
nLite is a program to slipstream the sata drivers to the XP install disc. CDburnerXP is a program you can use to copy entire disks and create and burn ISO images. Next you need to download the sata drivers for your laptop. Both ICH9 for Intel, and sata for AMD are HERE
. Download the correct version for your laptop and save this link as it also has all the XP drivers for a DV4.
Put your XP installation disk in your computer and copy the disc to a folder using CDburner. Now start nLite and point it to that folder to reference it to an XP installation. When you get to the modify screen select add drivers, select entire folder and browse to the sata drivers you downloaded. Continue and tell it to create an ISO image. After that is complete you can go to the ISO you just created and double click it to burn a fresh installation disk using CDburner. Now you have an installation disk that will install XP. After XP is installed go back to the link I gave you to download all the XP drivers for your laptop.
