This is the Compaq Presario C794TU, one of many Compaq laptops that has your well desired specs and performance. This Laptop comes with a pre-installed Windows Vista® Home Basic.
For a Vista laptop, I can say that it performs well given the limited 1 x 1 GB DDR 2 RAM that came pre-installed. Typical applications such as Yahoo Messenger, Skype, MS Office 2007, and Adobe Photoshop CS2 load in under six (6) seconds. The manual says that this lappy can accomodate an additional 1 GB for a maximum of 2 GB system RAM.
As for the optical media drive, it can read and write double layer DVDs (8.5 GB) which can store twice the capacity of regular DVDs (4.7 GB). This is particularly useful when burning large files like making recovery discs for the pre-installed Microsoft Windows Vista image stored in the 160 GB hard drive.

Based on my limited run, my presario’s 6-cell lithium ion battery’s power went down from 100% to 39% after one (1) hour and twenty (20) minutes of full-screen skype video conferencing over WiFi. The heat vent on the laptop dissipates the heat well keeping the laptop relatively cool despite hours of non-stop use in a non-airconditioned room.
This Unit Cost about Php 35,000, but that dosen’t have the added warranty and other added things when you buya brand new laptop.
