Acer Aspire 4520 vs Compaq Presario V3000AU : A wifi comparison

Intro
This is a first hand comparison between the wireless adapter performance between the Compaq Presario V3000/3155AU and an Acer Aspire 4520.

The test

The test I did is to ping the local wireless router / access point.

ping 10.0.0.1 -n 100


These is the result of Acer Aspire

Apparently the connection was too poor in Compaq, I had to use a pen drive to copy the statistics and post it here.

nVidia Core Temperature too high on my Compaq Presario Lappy

LAPtops as the name stands, conventionally meant to be on the LAP. But in my case not only can it be kept on a lap, it fries everything underneath !
Check out the screenshot!

nVidia GPU Core Temperature Screenshot


This is kinda normal, it gets to 110+ when connected to TV or playing a game!.

The nVidia GeForce card is suspected to do the overheating.
I am using a Compaq Presario V3000 Notebook.
Does any one having a similar series face the problem?
Any Solutions?
Has anyone tried cooking with this lappy? !
Please do comment.

:D

?
Finally after a lot of tweakin with the xorg.conf got Full Colour on S-Video Out on my Compaq Presario V3155(3000) AU, with an nVidia GeForce 6150 GPU on Ubuntu 8.04. The notable sections in the xorg.conf are the device section where you have to put the Option's right. You have to choose the right output SVIDEO or COMPOSITE and the TV Format,and in the Monitor section VertRefresh to 50hz also helped.

Please check your TV Manual for the correct VertRefresh Rate.
And the following table for the format






PAL-B

Australia, Belgium, Denmark, Finland, Germany, Guinea, Hong Kong, India, Indonesia, Italy, Malaysia, The Netherlands, Norway, Portugal, Singapore, Spain, Sweden, and Switzerland

PAL-D

China and North Korea

Laptop to TV using S-Video Out Port

This post is applicable only to those laptops that are equipped with a S Video Out port (like Compaq Presario V3000 Series). The S-Video Port looks like


S Video port can be used to connect to your TV using a S-Video to RCA Cable. The S Video end of the cable looks like this


You can buy the S-Video to RCA cable, but building it is pretty much simple and costs negligible.

All you have to do is,
connect the Pin 1 and Pin 2 of the connector in S-Video to Ground of RCA
and short the Pin 3 and Pin 4 of S-Video to the Main Pin of RCA.
Some sites recommend using a 470pF Capacitor in shorting the Pin4 to RCA, but i really don't find much of a different when skipping the capacitor. Thus its just a DIY (Do-It-Yourself) project to make your laptop a DVD/CD player or make your TV a secondary monitor screen.

Compaq Presario V3000 Settings
In order to use the S-Video port the NVidia GeForce Go Graphics Drivers must be installed and working.

Don't have an S-Video Port ?

Fedora Core 6
In FC6, changing the default driver from vesa to nv (nvidia) driver can cause the mouse pointer to disappear. Mouse pointer may be hidden or cannot be seen. So add the following lines to /etc/X11/xorg.conf to make it as follows :


Section "Device"
Identifier "Videocard0"
Driver "nv"
Option "HWcursor" "false"
Option "AddARGBGLXVisuals" "True"
