HP Compaq Presario C749TU Notebook PC – Windows Vista Performance

Everybody will be wondering… Can HP Compaq Presario C749TU Notebook PC run Windows Vista? Can it run with Intel Celeron 540 1.86GHz, 512MB RAM, 80GB HDD? I am using Windows Vista Home Premium to do the test. In short, Windows Vista cannot run on this system with 512MB RAM or less. 1GB RAM and above is highly recommended. Windows Vista uses up around 600MB RAM after boot up. Some memory was used as Video memory. It uses up to 800 RAM when play movie with Media Player. It does eat a lot of memory in Windows Vista.

Processing power is another factor we have to look into. Intel Celeron 540 1.86GHz which is single core processor will not run smoothly in Windows Vista on some applications. Dual core and higher frequency CPU is highly recommended. However, it still can run most of the office application, entertainment and web browsing. No 3D gaming with Intel Graphics Media Accelerator x3100. It is way too slow to run any popular 3D games. A dedicated powerful 3D card is required. 😛

Here are the Windows Vista base score that HP Compaq Presario C749TU Notebook PC gets…

The lowest point was contributed by Intel GMA x3100. As a result, this is definitely not a gaming platform. 😛

I did some benchmark with PCMark Vantage and 3DMark06. It did not performance well at all. And only score 1595 PCMarks while 413 3DMarks in 3DMark06.

Here are the PCMarks benchmark details…

  2. Hi

    I was wondering how do we install memory on the laptop . As this is the first time i have really played around with laptop internal. ( my experience is mostly with desktops)

    so what kinda memory do we need to buy for the 749TU and 777TU ( the new upgrade) . Is both the layout the same internally?..

  3. It is not hard to install laptop memory. I purchased 1GB PC667 DDR2 memory for my C749TU. Not sure about C777TU. But most laptop is using PC667 DDR2 now. 😀

  4. after install all vista driver from hp website, any1 has unknown device? 1 got 1 left and is to do with acpi compliant system. any solution?
