In this guide I explain how to upgrade RAM in HP Compaq nc8430, nw8440 and nx8420 notebooks.
In my example I’m using a Compaq nc8430 which came with 1 GB (two 512MB modules).
This model can take up to 4GB total. You can install up to 2GB memory module into each slot.
HP recommends using PC-4200 DDR2-533 SODIMM.
If you cannot find PC-4200 DDR2-533 memory, you can use PC-5300 PC-6400. They should work.

If your Toshiba Satellite L305D stopped showing video on the screen, there could be an easy fix for this problem.
First of all, test the laptop with an external monitor. If the external image appears to be fine, the next step is checking connection between the video cable and motherboard.
In this model the screen might stop working because the video cable gets disconnected from the motherboard.
I have seen a problem like that on a few different Satellite L305D and L305 laptops.
