OK - I wanted to add my experience since I've recently benefited by the various uses experiences and subsequent modifications noted in this thread!
Six years ago I purchased a new c552us that came equipped with an Intel Celeron 530 M, MS Vista, 1GB Memory (2 X 512 MB), and a 5,400 hard drive.
Within days of my purchase, I registered here, and found out the process of ditching MS Vista OS for MS XP Professional. Through the user experiences on this forum, I was able to pretty effortlessly make the transition, and operate for six years pretty problem free. Anyways, the mods I made the first week I owned my C552us it were:
* Ditching MS Vista for XP Professional (32 Bit Version),
* Adding 2 X 1GB Memory for 2 GB Total,
* Swapping out the 5,400 RPM hard drive for a 7,200 hard drive.
* Replacing the internal DVD/CD player with a HP DVD Writer I found used on Ebay,
* Upgrading to F24 Bios.
Since the upgrades, it's been my workhorse, serving me well as my primary computer for 6 years.
My c552us has literally been all over the world with me, from the hottest places on earth to the coldest places, and like others have written in this thread, besides it's bulletproof reliability, I've also greatly appreciate the LOUD front firing speakers. The factory internal sound card & speakers have been loud enough to allow me to listen to streamed internet radio and talk shows without needing external plug in speakers - greatly appreciated as it's one less thing to pack and carry. The sound card/speakers are loud enough that I frequently bring it into the bathroom, place it on a sink bank, and clearly hear talk radio shows over the sound of a showers running water.
Well, a few weeks ago the original motherboard died, and I was crushed. It was like losing a close friend. Hell we traveled the world together and I couldn't just trash him ;-)
So I started researching purchasing a new motherboard, and in the process I found this thread about upgrading the CPU - what a lifesaver!!!!.
OK - so my original motherboard was a: 445605-001 with a i943GML Northbridge - Manufactured 2006-10-18 REV 1
I was able to find the same board NEW on Ebay; a 445605-001 with a i943 GML Manufactured 2007-03-14 for $55 Shipped (pic below).
I also found a vendor that had a Intel Core 2 MOBILE CPU T5600 1.83 GHz CPU for $13 Shipped. I could have went with a faster dual core processor that also had more cache, BUT, I was very concerned about internal case temperatures. So I went conservative, and went with a combination that OShadowFoxO
said kept internal case temps pretty reasonable.
Here's a link to specs of the processor I picked:
In addition to the CPU upgrade experiences on this thread, I also found the following webpage very valuable to help me in my CPU pick:
Link to 445605-001 CPU Socket and processors that will fit in it:
I swapped out the bad motherboard for the new one, added the "new" T5600 CPU, and my old friend is up and running like a champ!
So now that I'm up and running I've been thinking... I know I'm a somewhat limited with the 533MHz FSB speed, but, the last mods I'd like to make (if possible) are:
* Bumping the memory up from 2 GB to???NOTE: In post 224 of this thread, "C500 fan" writes in his signature line that he has bios F26 and 4GB of memory.
Hmmmm, I wonder how that's working out for him, as in if he's able to utilize ALL of the memory, as well as where he found that BIOS version??? I see he's running Windows 7 64 Bit OS...He hasn't signed on for five months now - wish I could ask him!
* Replacing the Broadcomm B/G internal wireless card to a internal wireless card with "N" capability.
INTERNAL WIRELESS CARD UPGRADE
Regarding upgrading the wireless from B/G to N, I've found the following page at HP Austin TX.
It's for a SoftPaq Upgrade (sp38054) to, among the many models listed, the C500 Presario.
The SoftPaq allows the following: "Provides driver version 18.104.22.168 for Intel Wireless WiFi Link 4965."
The Intel 4965 is a A/B/G/N PCIe Mini Card that operates in 2.4GHz and 5.0 GHz spectrum, here's the specs:
I've been doing some initial research on this, and first off I notice I'd need to add a third antenna wire - and that seems like a small and easily fixed issue. BUT, what I've noticed from researching on Ebay is that there are many manufacture specific versions of the Intel 4965 (IBM, Toshiba, HP to name a few), in addition to a "generic" (for lack of better words) version of this card. Has anybody on this thread explored this conversion?Edited by fast_dave - 2/25/13 at 2:37pm
