• How does the build quality of laptops compare?

  - by pgwillia

  I'm looking to replace my 5 year old laptop. I want my next laptop to endure at least this long. I typically have Thunderbird, Firefox, Eclipse Java IDE, Skype, a ssh session, and Apache Tomcat running. I'm currently running Karmic Ubuntu, but am agnostic about operating system and would move to Win 7 or OS X. I frequently travel with this computer. I also value battery longevity and power conservation (if possible). Above all I'm looking to minimize cost. I think the hardware that best meets my needs is an Intel i7 processor, 8 GB RAM, 100GB @7200 rpm or SSD hardrive, and about 15 inch monitor. These specs are met by most brands. Does anyone know specific pros/cons and build quality for Macbook Pro, Lenovo Thinkpad (W510 or T510), Sony's VPC-F1190, and ASUS G Series G73JH-X1 NoteBook? Are all i7 processors created equal? Do you have other suggestion that meet my needs?

• How do you check Driver Verifier logs on Windows 7 after catching a faulty driver?

  - by Wolf

  I kept getting BSODs on a clean install of Windows 7 (plus updates), so I decided to run Driver Verifier. I had to select all drivers, since it didn't catch the culprit when I didn't include Microsoft drivers. I know it is not a hardware problem since everything is working fine on Linux and memtest86+ is not reporting any errors in the RAM (8 GB). This time, it caught the faulty driver and gave me a BSOD telling me so. Using WhoCrashed, I could verify what was the last error message with the parameters and the source. Yet, the source is always the kernel (ntoskrnl.exe) and the bugcheck this time was 0xC4 (0x85, 0xFFFFF9804429AFC0, 0x2, 0x11B948). After searching on the web, I found out "the driver called MmMapLockedPages without having locked down the MDL pages." As I am not developing any driver, this is of no use to me. However, I would like to know which driver caused Driver Verifier to trigger an alert, so I can either disable it, or rollback to a previous version in order not to get crashes anymore.

• How to view status of software RAID 1 resynching?

  - by tputkonen

  I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

• How to best migrate one Windows 2008 R2 / SharePoint / Exchange / Terminal Services (All-in-one) int

  - by MadBoy

  Hello, My client has one machine with Windows 2008 R2 and everything on it. By everything I mean AD, DNS, SharePoint 2010 Standard, Exchange 2010 Standard, Terminal Services, Office 2010 and a bunch of additional apps. Everything stands on I7 x 2 and 36gb ram for 7 people total. I've decided that we should virtualize it and split things into 4 VM's and keep host only with Hyper-V installed to host all the machines. What problems should I expect? What good advices can you give. My plan is that when i move everything to VM's i will move vm's to safe place and format the host as it has a lot of really bad things happening on it. But this also means that everything will be wiped from current solution so I have to be sure that Exchange etc will work when host gets wiped. MadBoy

• MacBook Pro screen goes dark

  - by Mike M

  I've had my MacBook Pro for two years now; no problems so far (it has had 3rd party RAM from the get go). Today, I'm copying a particularly large VM from an External disk drive to local MacBook disk. It has about 3GB to go and I take off to do some other things and when I come back my screen is "dark". The computer is still on but I can't see anything. I forced a reboot by holding down the power button, it starts up with the "chimes", but still no screen. I've done this several times. Any ideas? Do you think the hard disk activity caused it to get too hot?

• How do I overclock a dual core processor?

  - by Pankaj Bhardwaj

  This is a serious problem. I want to speed up my compilation process. I have never been especially fond of overclocking, however my current compilation time for my project makes my crazy! I found information about which parameters I should change to overclock and which values are safe. However, I have one basic problem. I don't have the ability to change this option in my BIOS. It is possible that these options have been blocked by the system administrators? Getting a faster processor is not an option. How do I edit the proper values to overclock my CPU. Do I need to flash my bios to another version? My specs: Entium Dual-Core Cpu E5400 @2.7GHz Asrock motherboard 4GB RAM Windows 7 Ultimate 32-bit

• About the External Graphics Card and CPU usage

  - by Balaji

  Hi, We are Rendering 16 live Streams at our client machine through one of our applications and the resolution of the video streams are as 4CIF/MPEG4/25FPS/4000Kbits. The configuration fo the client machine is below. HP Desktop Machine: Microsoft Windows XP Intel (R) Core2 Duo CPU E8400 @ 3.00 GHz 2.99 GHz, 1.94 GB of RAM Intel (R) Q45/Q43 Series Express Chipset (Inbuild) The CPU usage of the machine peaks 99% for 16 straems. After some discussion, we had decided to install external graphics card to reduce the CPU usage. So that, we have tried following graphics cards. NVIDIA Quadro NVS 440 - 128 MB Radeon HD 4350 - 512 MB GDDR2 Redeon HD 4350 - 1GB DDR2 ASUS EAH 4350 Silent 1GB DDR2 But the performance wise no difference, even worst. So, what is the pupuse of these external graphics cards? Really it will reduce the CPU usage? What parameters have to check, if we want to reduce the CPU usage? Please do the needful as soon as possible. Regards Balaji

• Windows 7 has trouble installing software with Visual C++ 2005 & 2008

  - by John Fitzgerald

  I have been reinstalling Windows 7 over and over again on an ASUS P5lD2 2Gb Ram 3Ghz P4 because it ultimately loses the contents of "Turn Windows Features On or Off" after I install software like Autocad 2010 & Microsoft Office 2007. I get install errors like 1935 and 1704 on the way tried different fixes at different times (install software in different order to try and isolate problem too). Ultimately I force the software to install after much buggering and end up losing the contents of "TWFOOO" Should I be installing some older items like .net framework 1.1, 2.0 and Visual Studio items like vcredist_x86.exe? getting a bit lost because of compounded problems...

• "This CPU is not compatible with 64-bit mode." - Installing Windows 7 Ultimate 64-bit on a netbook with a 64-bit Intel Atom CPU

  - by galacticninja

  I tried installing Windows 7 Ultimate SP 1, 64-bit on a netbook (Lenovo IdeaPad S110), which has the Intel Atom N2800 (1.86 GHz) as its processor, but I get the following error message when the Windows 7 installation DVD is loading: It says "Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode". The Intel Atom N2800 is a 64-bit CPU according to its webpage. I am wondering why the Windows 7 installer shows this error message, despite this. Is there something I must configure first before installing Windows 7, 64-bit? Or is the netbook not compatible with a 64-bit OS? I am trying to format the netbook and install Windows 7 Ultimate 64-bit, instead. Other details: The netbook has 2 GB RAM. The netbook initially had Windows 7 Starter (32-bit) installed.

• Limit disk I/O one program creates?

  - by Posipiet

  Hardware: one virtualization server. Dual Nehalem, 24GB RAM, 2 TB mirrored HD. Software: Debian, KVM, virt-manager on the server with several virtual machines that use Linux too. 2 TB Disk is a big LVM, each VM gets a logical volume and makes its own partitions in that. Problem: One of the programs that runs on one of the VMs creates huge disk load. This never was an issue, because the program never ran on such a powerful hardware. Now the CPUs are fast, and lots of I/O is the result. We cant do much against that at the moment, because the tool is a black box. On the other hand, the speedy computation is welcome. The program creates about 5 GB of temp files which get overwritten during the next iteration. Question: How can we limit the disk I/O for the process?

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

• Firefox Not responding - Windows 7

  - by Paul

  Have just upgraded from Vista to Win7 (32 bit). On vista Firefox worked great. I am using 3.5.6 version. 2GB RAM. In windows 7 however whenever i click on a link, field or tab within the browser or various other places within firefox 'Not Responding' flashes on the title bar. Most of the time i have to click 2 or 3 times to get any link or whatever to work which is very annoying. Any ideas? Can't find anything obvious on google but notice other people get Not Responding messages a lot with various apps. Chrome Plus seems to be fine.

• Why did my laptop turn off?

  - by darenw

  Normally I can slip my running laptop into a backpack, go somewhere, and if it's no more than about half an hour later, it'll still be running. At the destination I plug in the AC power unit and all is well. I run it off of the AC unit before and after the trip, have the screen at less than full backlight brightness, and don't have any peripherals that burn power. Sometimes the wireless switch accidentally slides in the backpack, and that causes extra power to be used and the laptop dies before I reach the destination. Sad, but so be it. But sometimes the wireless switch is off, I've reached the destination in less than 30 minutes (typically 10-20 min), and I know the battery was fully charged, yet the machine is off. Is there a way to determine, after the fact, why the machine shut itself off? I'm running Linux on a fairly powerful Gateway with 4GB RAM, fancy nvidia graphics, dual core cpu, chosen more for number crunching power than battery life, but should last easily for half an hour if not an hour.

• Moving the OS X swap file to a faster drive

  - by Milky Joe

  I have a new Mac Mini that's running the latest version of Snow Leopard. The internal drive is a bit of a slouch. I'd like to move the swap file (or whatever it's called is OS X) to my faster external drive (Firewire 800, permanently connected). Is this possible? I've read that the old solutions aren't working in 10.6. My Mac has 2GB of RAM, so the swap file is used quite a bit when I'm doing intensive work (Photoshop etc).

• Tracking down random BSOD on windows 7

  - by pehrs

  I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

• Why is hibernation still used?

  - by Moses

  I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

• BSOD constantly with same ntoskrnl.exe error and disk indicator is frozen

  - by Sheep

  BSOD constantly and the disk indicator is frozen. Error do not happen immediately, usually an hour after boot up. Here is the Minidump: Bug Check Code = 0x00000124 Caused By Driver = ntoskrnl.exe Caused By Address = ntoskrnl.exe+4b094c Crash Address = ntoskrnl.exe+4b094c Seems to be hardware problem, but I checked RAM, no error. I have two HDs installed, system is on SSD, data is on HDD. Checked SSD with the properties-tools-error-checking , no error. Re-installed several times, still happens even after removed HDD. Configuration: SSD: Crucial M4-CT064M4SSD2 with Firmware 0009 Intel HM65 CPU: i7-2630QM The SSD is set correctly, SATA III 6Gb/s enabled, and everything worked perfectly for nearly a year.

• Clear / Flush cached memory

  - by TheDave

  I have a small VPS with 6GB RAM hosting a couple of websites. Recently I have noticed that my cached memory size is quite high - see below: Cpu(s): 0.1%us, 0.1%sy, 0.0%ni, 99.1%id, 0.0%wa, 0.2%hi, 0.4%si, 0.0%st Mem: 6113256k total, 5949620k used, 163636k free, 398584k buffers Swap: 1048564k total, 104k used, 1048460k free, 3586468k cached After investigating if there is some method to have this flushed or cleared I stumbled upon a command which is: sync; echo 3 > /proc/sys/vm/drop_caches I read it could be useful to add this to a chron-task/job. Is this method recommended or could this lead to potential problems? The only concern I have is that I use one Magento installation on Memcached - could this have any negative effects on it? I am certainly not a pro therefore I would very much appreciate some expert advise. PS: My VPS runs on CentOS 5 x64 and I have WHM + NGINX installed.

• Cutting and pasting in MS Word: hourglass pops and it takes longer than expected

  - by Rax Olgud

  I work with MS Word 2007. Today I created a new document, and for some reason cutting and pasting text (using Ctrl-X and Ctrl-V) takes longer than expected. To clarify, here's the process: I select a single word in the document I click Ctrl-X The hourglass shows up for 1-2 seconds The word is cut The same happens for pasting (i.e. 1-2 seconds of hourglass). This document is ~5 pages long, with nothing fancy. I have plenty of available RAM and my CPU usage is around 1-2%, there's not peak during the cut/paste. Any thoughts on what can cause this and what I can do against it?

• VMware ESXi 4 On-Disk Data Deduplication - possible and supported?

  - by hurikhan77

  Environment: We are running multiple web, database, and application servers which usually share a pretty common installation (gentoo linux) and similar configuration in VMware ESXi 4. The differences are usually only some installed features or differing component versions. To create a new server, I usually choose the most similar (by features) running server, rsync a copy of it into freshly mounted filesystems, run grub, reconfigure and reboot. Problem: Over time this duplicates many on-disk data blocks which probably sums up to several 10's of gigabytes. I suppose if I could use a base system as template with the actual machines based on top of that, only writing changed blocks to some sort of "diff image", performance should improve (increased cache hit rate) and storage efficiency should increase (deduplicated storage space). This would be similar to what ESXi already supports for RAM deduplication (page sharing). Question: Is there any way to easily do this on ESXi 4? I already share the portage tree via NFS but this would not work for the rootfs.

• BSOD when playing Portal 2 using ATI Radeon 4800 on H61M/U3S3 mobo

  - by Ben Walker

  playing Portal 2 will always give me blue screen of death, usually after about 10 minutes of playing. BSOD references atikmpag.sys. I have tried several updates for graphics driver and through ATI Catalyst Center. I have updated the motherboard BIOS. My RAM is OK. Nothing changes. I had previously run the game fine, then I removed my video card to use on-board graphics once, and after re-installing the video card, I get this problem every time.
