I’m considering upgrading my laptop’s CPU but don’t know what to use as a replacement. My laptop is a Dell Latitude D820 with an Intel Core2 T5500. This CPU does not support virtualization, so I am looking to replace it with a CPU that does. How do I go about figuring out which CPUs go with my laptop motherboard? If I am going to void my (very expensive) warranty doing this, I want to be sure that I have the correct part.
I love my PC, but it has just gone wacko! I keep getting this error on Windows XP: “Parser message: Value creation failed at line 544.”
I put my PC to sleep, but the message pops up repeatedly before it will sleep. Once it returns from sleep, the same message pops up five times, followed by the Classic startup screen. I don’t use the classic theme, but I couldn’t figure out what was going on so I just dismissed the error and kept playing the game I was playing. The next day the error was back. Help!
I have Windows 7 and when I start a game like the Homeworld 2 demo, my processor refuses to go below 50 percent usage. When I look in the Task Manager the process called rundll32.exe is using 50 percent of the CPU cycles. I ran an Avast scan; there is no indication of a virus. I can fix this by suspending the task and the games run fine without the rundll32 task going. Any idea of why this is going on?
I have an HP Pavilion zv5001us laptop that is about six years old. It has a Phoenix BIOS, if I remember correctly. Whenever I try to access the BIOS, the computer prompts me for a password. I forgot the password and don’t know how to get around it. Thanks.

Gone are the Atom processor’s days of monopolizing the low-cost mobile-computing market. This should come as welcome news to folks who want the price and portability benefits of a netbook but more robust performance.
Take Toshiba’s Satellite T115 as an example. To say that it has an 11.6-inch diagonal screen, weighs 3.6 pounds, and is coated in a high-gloss black finish inlaid with a subtle geometric pattern is to describe any number of netbooks on the market today. The fact that the T115 costs $480 only drives home the similarity.
And yet, the T115 is different from netbooks in one very significant way. It houses a traditional notebook processor. It’s just a single-core, single-threaded, 45mn, 1.3GHz Pentium M, but that proved plenty sufficient for making mincemeat of our zero-point netbook’s benchmark scores. That machine’s Atom N270 is clocked 23 percent higher at 1.6GHz, but the Pentium beat it by massive margins—from 27.4 percent in MainConcept all the way up to 128.7 percent in 3DMark 03.
Can we use Windows 7's new fast-boot capability and BIOS optimizations to get to the desktop in less than 30 seconds?
If you’re the kind of person who fumes at the microwave because it takes so long to nuke popcorn, you probably can’t stand the plodding boot of your PC, either.
And who can blame you? Time spent waiting for first the BIOS and then Windows to come to life is time that could have been spent working, gaming, or surfing the web.
Microsoft’s claim that Windows 7 could boot (from the BIOS) in 11 seconds first gave us the hope that such idle time might be lessened dramatically, but being Maximum PC we wanted to take the idea even further. We sought to not only replicate Microsoft’s claim, but to see how much time we could shave prior to the OS loading, with a combination of hardware and BIOS tweaks. Our ultimate goal: to have a machine up and running within 30 seconds of hitting the power switch.
So if your attention deficit disorder hasn’t already caused you to click to the next story, find out how we were able to achieve the shortest boot possible.
We saw how splendid an IPS monitor can be when we reviewed Dell’s 24-inch UltraSharp U2410 in January. “Sometimes you have to pay to play,” we concluded. Moments after reaching that summit, we observed NEC’s 30-inch LCD3090 WQXi IPS panel looming before us. Fully aware that we could buy three U2410s and a Radeon HD 5870 to drive them for about the same amount of cash ($2,200, to be exact), we began our ascent.
The LCD3090 has a native resolution of 2560x1600 (a 16:10 aspect ratio), which is typical of 30-inch displays. This one is an eight-bit panel with programmable 12-bit lookup tables. It delivers 102 percent of the NTSC color space and 97.8 percent of the Adobe RGB color space. Inputs are limited to dual-link DVI-D with an odd HDCP on/off feature, and DVI-I. Why would you need to turn off HDCP? We’re not really sure.
There’s no media card reader or integrated USB hub; more importantly, there’s no DisplayPort support, either. But the stand tilts, swivels, and pivots; and if you still can’t find a comfortable position, you can mount it on an optional articulated arm using its standard VESA mount.
