  • Scanner Daily Duty Cycle

    - by Juanp
    I'm comfused with the concept of 'Daily Duty Cycle'. For example if I have a scanner that the spec is: PPM (pages per minute): 90 and DDC (Daily Duty Cycle): 800. I am interested in scanning ONLY 10 hours continuously, what would it be the best choice: 90 * 60 * 10 = 54.000 or (800 / 24) * 10 = 333 It is very different results. what would it be the best option?

  • Does it mean video card is broken?

    - by Sejanus
    Hello, I've just installed some sort of relatively old video card and now computer freezes while playing certain video games (Civilization 4, HOMM V). Some other video games with far better graphics works well (Dawn of War I). Note that "freezing" games runs nicely and smoothly for about 10-15 mins, no lag or any other indication that video card may be not good enough. And then PC suddenly freezes, nothing works but rebooting. The question is, is this a normal behavior of a video card which is simply "not good enough" for the games in question, or is there something broken? Card itself or motherboard or whatever? OS is Windows 7 if that matters, and I don't know exact videocard specs but that probably doesn't matter for this sort of question... thanks in advance!

  • Decyphering Seagate drive model numbers?

    - by Stefan Lasiewski
    I'm comparing Seagate's Enterprise and Desktop drives for a variety of old and new servers. These servers come from different generations, so options like size (73GB, 2TB) and interface (SATA vs SAS 3.0Gbps vs SAS 6Gbps vs SCSI Ultra320) are widely variable. I'm trying to compare the sizes, speeds and interfaces, but I'm getting thrown off by different models. Also, their website is not the best. Does anyone know of a documented explanation of the Seagate model numbers? And is there a single spreadsheet which compares the features for all drives (or all 'Enterprise' drives?). Seagate drives have model numbers like this: Model ST3600057SS 6-Gb/s SAS 600 GB None at Cheetah® 15K Hard Drives Model ST373455LW Ultra320 SCSI 73.4 GB 68-Pin LW at Cheetah® 15K Hard Drives Model ST32000644NS SATA 3Gb/s 2 TB None at Constellation™ ES Hard Drives Model ST973452SS 6-Gb/s SAS 73 GB None Savvio® 15K Hard Drives Model ST9200011FS SATA 3Gb/s 200 GB Pulsar™ Solid State Drives I understand the model numbers read something like this: ST - SOMETHING1 - SIZE - SOMETHING2 - INTERFACE Where the fields mean something like this: ST : For 'Seagate'? 'Seagate Technoligies'? SOMETHING1 - This field has number, but I'm not sure what that represents. SIZE - Size in Gigabytes. This is a number like '73' or '300' or '2000' SOMETHING2 - This field also has a number, but I'm not sure what it means. INTERFACE - This field seems to indicate the Interface. 'SS' means SAS, 'FC' means Fibre Channel, but I don't see how to distinguish between 6Gbps SAS and 3Gbps SAS, or different SATA or FC speeds. I don't see a field which indicates the RPM (15K , 10K, 7.2K) etc. Is this part of the model number?

  • Testing Firewire 800 port on MacBook Pro

    - by dtlussier
    I am having trouble getting my MacBook pro to mount an external Firewire hard drive. I am able to mount the disk no problem on other Macs, just not my machine. I haven't received any errors from my machine, and don't see anything related to the Firewire port in the logs. Are there good diagnostic tools for this type of problem that come with the Mac? other free alternatives ?

  • Windows 7 Homegroups not working?

    - by Jonas
    I've got a homegroup set up, and only the accounts/machines where the user and password is identical can see/share files. I thought the setting to let homegroup control the accounts would make that requirement unnecessary....am I missing something? To be clear: I can see the other machines/user accounts in my homegroup listing, but I can't see any of the files in their shared libraries.

  • Is it a good idea to have the operating system on a solid state drive?

    - by Kenji Kina
    There is something I don't quite understand. I know a SSD helps with OS load times, but I'm not sure if all this boost is only noticeable/interesting when booting, or gives an all around considerably better experience thereafter. I am interested in having a quick and responsive environment after booting, which leads me to think that it'd be better to spend the SSD capacity in my most used apps (and the page file? Another inside question) and not the OS itself. This, of course, means that I don't know just how much the OS reads/writes its files during normal usage. So, how good an idea is it to dump the whole 20GB+ of Windows 7 OS into the SSD (considering the hefty price per GB of SSD capacity) if I can put up with the usual hard disk boot times? Would I be missing on a lot if I didn't?

  • Windows File Server -- Where To Start

    - by yodie
    I have a Windows 2003 server, a whole load of PDFs on it that need to be accessed from various computers, both on the local network and not, and including mobile devices, and files that have to be sent to it. Where do I start? The most important thing (after getting the job done) is security.

  • Can two Identical devices be present on the same bus in any PCI Topology

    - by vaibbhav
    As per the PCI standard, devices are identified on the basis of Vendor Id, Device Id and the bus no. All devices of same type have identical vendor id and device id. If I put two such devices on the same bus say bus 0. How will the PCI Software Subsystem distinguish between the two? If such a case is not possible in PCI, then can such thing be possible through PCI Express Switch?

  • Suggestions for wireless adapter

    - by Michael Kniskern
    I recently purchased a desktop computer and it did not come with a wireless network card. I am currently using the Belkin Wireless G USB Adapter and it is a very sub par product. It has very slow response times and download speeds with just basic browsing and downloads podcasts through iTunes. Does anyone have a better suggestion for a wireless adapter? Should I go with another USB adapter or one that connects directly into the motherboard? I am current using Windows Vista 64 bit Home Premium.

  • How to get the installed Memory Type

    - by balexandre
    Windows 7 could be better at this, it tells everything about the computer CPU but only the Memory amount Microsoft should add information about DDR type, speed and maybe CL as well. While this never happens, What's the best and easy way to check the installed memory so we can buy and upgrade it? I was thinking a simple software so I don't need to install the full SiSoft Sandra for example, just looking for something small, only for the memory part.

  • Desktop PC does not power up on power button

    - by hIpPy
    When I press the power button on my desktop, it does not power up completely. Before I press the power button, I see lights on the motherboard. Everything is normal. On power button press, the fans on the cpu, graphics card and motherboard start to spin a little for a second or two and then they stop. No beeps during this process. It has been doing this for a while now but it used to start up after some trials. Once it starts up, I have NO issues at all like random shutdowns so it is not an issue with OS. I'm just guessing here but it seems as if the PSU (Antec TP2-550ATX) is dying out and does not have enough power now - just a guess. It's an old desktop assembled in 2005 but I have maintained it well. Any ideas? Please help. Thanks. Below is the complete configuration.

  • How do I clean dust from a computer?

    - by Jonas
    As computers become faster and generate more heat it gets more important to have good ventilation, but that also increases the amount of dust sticking to the components of the computer. It's of course better to make sure the computer never gets dusty by vacuum cleaning around it (not in it) frequently. But what to do if it's already to late? I've heard that vacuum cleaning the computer itself is very bad, since it can cause static electricity that hurts the computer. So, Does anyone have any tips for how to remove dust from your computer?

But just found out that recently that I already have 2x2GB installed and should be 4GB in total. When I looked at the properties of my computer, It said "Installed Memory 2GB". I wonder why is that happening? Is the other ram broken?.. I never the computer casing since I bought. so I didn't realize that I already have 2 x 2gb ram. what can you advice. Thanks!

  • External USB disk drive cannot be remounted in Windows XP

    - by jackhab
    I have Maxtor Basics Desktop 1TB external USB drive connected to Windows XP. The dirve's firmware puts it to sleep after 10-20 min of inactivity and then the drive cannot be mounted unless I reset it via power connector. While in sleep mode I can see the device in the Device Manager under both Disk drives and USB sections. Is there a way to get the drive out of sleep mode without hard reset? Thanks

  • How can I find a laptop if it has a different model name all over the world?

    - by Mike
    CONUNDRUM: A laptop review in the UK talks about how brilliant the "ASUS ABCDE 55" is, but in America, France, etc there is no such laptop name. In fact it's called "ASUS 12345 AB" - AAARRGH! QUESTION: Is there a way of finding out all the diverse names for the same laptop all over the world? Example: if Samsung create a R2D2500, then what is that spec laptop called in all the other countries (if they release it of course). Or if it's not released, what is their similar spec laptop called in the other countries? I understand that specs may be different, but if I read a review on my trusted UK website, but live in say Australia, I want to be able to find the name of the same laptop in Australia and then check out local places to buy it. So if anyone knows if there is a technique, specific website, or even how to use a company website to find out these annoying name changes I'd really appreciate it.

  • Looking for a good computer repair kit

    - by johnny
    I'm afraid I'll get ripped if I get the generic kit from Tigerdirect or whatever. For clarity this is not software I am after but physical tools. It should include something for occassional soldering of electronics, crimper, other things I cannot remember. Hoping for ideas or product links (yes I am searching also). Thank you.

  • Can anyone explain these cpu specs?

    - by Kevin
    Intel® Core™ i7-640M (2.8~3.46GHz, 35W) w/4MB Cache - 2 Cores, 4 Threads - 2.5 GT/s SO i'm buying a new laptop, which i have not done in 6 years. So i am not familiar with any of these cpu specs. It was the highest option for intel for this laptop. So i am assuming it is somewhat fast. But i'd like to learn what these specs mean. Any help would be greatly appreciated. i am not really a computer guy but would love to learn about what I am buying. Thanks!
