  • About HDD enclosure

    - by kmitnick
    hey guys, how r u doin? I have this 3.5" IDE enclosure, and it works great, I mean I love the idea of enclosures ( not the power feeding thing :), btw can't I just insert a chargable battery to feed the power when I am unable to find an electricity block), anyway my question is, when I finish the usage of the enclosure I safely remove it when using Windows or umount when working with Linux, and after that I got confused whether to turn it off or no? when I turn it off, the HDD suddenly stop spinning as if power failure not as when it was an internal and normally shuted down the pc. So is it ok to turn it off the way I've just said??? regards, ~Abed

  • How does one calculate voltages for overclocking?

    - by TardisGuy
    So, all I know is voltage and clock have something to do with each other. Unstable if too low voltage Too high voltage, and too much heat. or higher voltage + lower clock may heat less than that voltage at higher clock. The reason why im asking is because if I can learn how the power vs speed works, Then i might be able to project some kind of thermal curve to find out where my perfect overclock might be (without 50 burn-ins) But, as is apparent im sure. I have no idea what im talking about. If anyone can help me learn more about this; throw me a page, a macro, whathaveyou I will bow before your awesomeness and... Mail you a phantom hand written thank you letter. Some clarification Rev 1 What im trying to learn: is how much power a cpu is using with measurements (Core Voltage) vs (Clock speed) - It would answer the question: Would a 1.4v core @ 4.0Ghz use as much power as a 1.4v core @ 3.0Ghz?

  • Can't Shut Down computer with windows 8 Release Preview

    - by Bram Winda
    I downloaded Release Preview and installed it. I have a problem when I shut down the computer. After I press windows key + I Power Shut Down, a box pops up titled "Winlogon.exe - No Disk. Then under that is the message "There is no disk in the drive. Please insert a disk into Drive G". After hitting the retry button a couple of different times the screen finally goes dark. When I was going to turn it back on, I noticed the Power Button was still list. The only way to do a complete Shutdown is to hold in the power button directly. How do I fix this problem?

  • scheduled chkdsk on Windows 7 blinking the hard disk light every 5 seconds, what can I do?

    - by Jian Lin
    PG&E (the local electricity company) came and took out the old power meters and put in a new ones by brute force and with no advance notice in our neighborhood, so my computer went down in power. So I went to Windows 7's drive C and schedule a Disk Cleanup (chkdsk) on the next boot up. When it boots up, it says A disk check has been scheduled To skip disk checking, press any key within __ second(s). and then after it shows To skip disk checking, press any key within 1 second(s). it just sits there, with no further message. the hard disc light blinks every 5 seconds. So what is to be done now? I certainly don't want to brute force power off again.

  • How to lock screen in linux before hibernating?

    - by Emanuel Ey
    So when i hibernate my laptop the screen doesn't lock automatically. To solve this i've changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

  • Suspended Laptop Cannot Wake Up - Ubuntu

    - by Zack
    I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue?

  • Cables for building a computer

    - by Faken
    I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

  • Notebook computer battery says: plugged in but not charging with no further information. Is the bat

    - by Jian Lin
    My 1.5 year old Dell Studio 15 notebook computer has a battery and I keep it attached to the notebook but 98% of the time I just plug in the power adapter. Lately when I unplugged the power adapter, the battery was only good for 10 minutes, and a few days ago, when I unplugged the power adapter, the computer simply turned off. When clicking on the battery icon on Win 7, it says "Plugged in, not charging": is the battery dead? Or can Win 7 have any option to not charge the battery? It is a Dell Studio 15, I wonder if in such case, it looks like it can be a manufacture's defect, would Dell replace the battery? (if there was a recall, then they probably would, i think). The notebook is 1.5 year old.

  • While updating the firmware on my parent's WNR3500v1, I bricked it

    - by Matt
    While updating the firmware on my parent's WNR3500v1, I bricked it. Basically, all that happens now is the power light just flashed. I tried pressing the factory reset button for up to a minute with the power on as well as with the power off. To no avail. Is there anything that can be done other than try to RMA it? Googling around, I found nothing promising. I'm wondering if anyone else has any other solution.

  • Ubuntu 9.10 is not starting on netbook

    - by anonymous
    I installed Ubuntu 9.10 onto my external hard drive cause it's cool to be able to borrow a friend's laptop and be able to have my entire system. It works on the 2 systems i tested it on: my desktop and my mom's laptop. I had to work on something earlier so i borrowed my friend's netbook. I started it up, chose Ubuntu 9.10.20 and it got to the Ubuntu loading screen with the 3 people holding hands right before user selection then it suddenly went black. Naturally, i freaked out because it wasn't my laptop. I held the power button down and reset the netbook but the screen was still black, it didn't even show the BIOS. I repeated the process without my hard drive, and it was still black without the BIOS showing up. I had to remove the battery, plug it to a power source, and power up to start the netbook up again. Can anyone tell me what happened?

I am wanting to find the cheapest solution on adding another monitor, I have a old ati x300 laying around and wanting to know if I would be able to use that to power the other monitor and if it would conflict with my other graphic card (I am not a gamer). What I want to do is have the at x300 power 1 monitor via dvi and the gt 120 power 2 monitors via vga and dvi. Thanks edit: im running windows 7 64bit

  • How do I diagnose a HP Notebook which has hardware issues?

    - by Rob
    My HP DV6t-2300 recently crashed while using FLV Player. It wouldn't start up after this so I had to do a hardware reset (remove power sources, hold down power button ~15 seconds, put back power sources). After this it would turn on, but start up would freeze in Ubuntu, Windows 7, Ubuntu Recovery Mode, and various Linux Live CDs. The only successful way to boot was in Windows 7 Safe Mode. The HP Customer Service was very polite, but they are trying to blame it on a corrupt operating system which is clearly not the case (since I have tried 4 operating systems and none work). I am thinking it might be the GPU since 1) I was watching movies when it crashed and 2) Windows Safe Mode might not use the dedicated GPU. I already ran Memory and HDD tests and there were no detected errors. Any ideas of what's wrong, or suggestions for tests that I should run in safe mode? Should I try reinstalling Windows 7 to convince HP that it's not the OS?

  • Laptop charger disconnects and reconnects, charger or battery broken?

    - by Rob
    I've got an Acer Aspire One netbook (AOA-150) and there's obviously something wrong with it. The charging port gets VERY HOT and the charger seems to disconnect and reconnect quickly sometimes. This only happens when the netbook is running, and it doesn't seem to care what it's doing other than being on. The battery has an extremely short life (< 30minutes, sometimes) and I almost exclusively run it on the power cable (which needs the battery plugged in. Having it just plugged into the wall won't start up). Does this sound like a problem with the power cable or the battery? The plug for the cable and the port get so hot that if I held them for longer than a few seconds, I'm sure I'd get burnt. EDIT Just got "Popular Question" on this and it WAS the power jack. The ground on it came loose from the board. A bit of solder on it and everything is working great again.

  • Graciously shutdown external HDD enclosure?

    - by Jakobud
    I recently purchased a large HDD along with the following HDD enclosure: http://www.newegg.com/Product/Product.aspx?Item=N82E16817173043 It has a simple on-off switch on the back. When I want to turn this thing off, do I simply just flip the switch? I assume the switch simply kills the power to the HDD, but isn't that potentially a bad thing in the case that the HDD is still reading/writing? I used to have a Seagate external HDD and it had a button on the front that I had to hold down for a second or two before it would turn off, but it at least appeared to sort of go through a shutdown procedure where it probably would stop the HDD activity before cutting power. So with this external HDD, I'm a little bit leery about that power switch and understanding exactly what it does. Is this how all HDD enclosures are? EDIT: I'm running the drive in Ubuntu Server. So there is no 'ejecting' the drive lol

  • Does a portable secondary laptop LCD monitor exist?

    - by Dougnukem
    I'm looking to buy a portable secondary LCD monitor for my Macbook Pro, does anything like that exist? I found some laptops that provide a dual 15'' monitor solution (but it's already baked into the hardware). Also some ideas posted about creating this type of setup back in 2007. I'm looking for something that is as thin as a laptop LCD (with maybe a bulky power supply that I could easily daisy chain or plug into a power strip along with my laptop). How difficult would it be to buy a 17'' laptop screen and hook up a DVI connector and power supply, and build a simple monitor stand for it? I've gotten to used to a dual-monitor setup at work and at home with my laptop that having to use my laptop in single-screen mode makes me feel crippled.

  • Is it my motherboard?

    - by jarodrussell
    Early this week my home server (a Linux machine) threw a kernel panic. Yesterday is happened a couple of times. Then all of a sudden, when I plugged a USB stick in to run a memory test, the monitor stopped coming on. Now whenever I turn it on, the system gets power...I heard the drives spin, I see the processor fan spin, and the hard drive light comes on...but nothing happens. I put a video card in the AGP slot, but still nothing. The light on the power button that usually comes on stopped coming on. I took the memory out to see if it would beep, but nothing beeped. It's like it's getting power, but it's not coming on. Does this sound like a motherboard problem to anyone else? I think it is, but a second opinion would be greatly appreciated. Thanks.

  • Keep lan connection alive while going to sleep

    - by user18151
    Is it possible to keep lan connection alive when going to sleep? Although I would like a laptop independent(in general) answer, my laptop is Thinkpad T500 and the power manager shows in PCI options, the following three option regarding saving link state power: Off, moderate, maximum. Also instant resume apparently does something different, so that isn't much help either. I'm on Windows-7. Here's why: I'm a student, and currently I keep my laptop on almost all the time, but sometimes I sleep it and then I require to check something, so I turn it on. But then internet starts in at least a minute. So I avoid even putting it to sleep. I want that the internet connection should persist, so that I can put it to sleep to avoid power consumption.

  • EMC CX3-10c Fault Condition won;t clear

    - by ITGuy24
    We have an old CX3-10c from Dell that had both Standby Power Supplies (SPS) fail. This obviously caused a fault on the system and disabled the cache. We have replaced the SPS's and they test fine as do all other components. Problem is there is still a fault on the "Enclosure SPE [SPE3]" despite all the component in the enclosure showing as good. I was on the line with Dell Gold support for 3 hours yesterday, they have had me restart the SPs multiple times, as well as reseat the power supplies, even shutdown the system completely and power it back on. All to no avail. Fault remains and cache cannot be re-enabled so long as the Fault is present. Any suggestions on clearing this erroneous fault?

  • 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.

  • What do I need to connect a hard disk to my laptop via non powered eSata?

    - by Ludo
    Hi there. I'm looking at getting a hard disk for my laptop (OCZ Vertex 2 SSD) which I would like to connect via eSata. My laptop has an eSata port, but it's not powered (Thinkpad T410). I presume this means I need more than just an eSata to eSata cable as it needs power, so does this mean I need a caddy for the hard disk as well which will provide power to the drive, or do I need one of them eSata cables that has a USB attachment too? I don't think the drive will come with a power supply. I realise this seems simple but I can't find an obvious answer online. Thanks for any assistance! Ludo.

  • 3 wire computer fan won't run continuously

    - by Ben
    I had an old computer that didn't work anymore, so I took the CPU fan out to see what I could make with it. The fan is NMB model number BG0903-B044-VTL, like this. It has three wires coming off of it, red, black, and white. I know that the white wire is usually a speed sensor. Does this wire need to be connected to something in order for the fan to run continuously? Right now when I apply power to the red and black wires (from a 9-volt battery) the fan will spin very briefly, and then slow down until it stops. The fan's motor only spins in the instant that the power is turned on, but doesn't continue, even though the power is still applied. How can I get the fan to spin continuously?

  • help building a PC that can image a dozen hard drives simultaneously

    - by Bigbio2002
    Not sure if this belongs on here or SuperUser, but here goes... I'm trying to figure out how to make a mass hard drive imaging PC out of COTS parts. A dedicated imaging device can do 10 drives at a time, but costs several thousand dollars. So far, I'm thinking to use several 3-port PCI-E Firewire cards, and use some kind of Firewire-to-IDE adapter to connect the drives themselves. The "software" would consist of scripting diskpart, or some other imaging utility. The problem is that I can't seem to find any sort of adapter. I could use standard external hard drive bays, but then I'd have a dozen power cables that I need to plug in. Ugly, messy, and inefficient. I picked Firewire over USB not only for better transfer speeds, but also because FW can deliver power over the bus (and could theoretically power a hard drive). Does anyone have any input on this?

  • ASUS EeePC 1001PX, hard disk clicking in Ubuntu Maverick

    - by MeanEYE
    I just received my new Asus EeePC 1001px netbook. After installing Ubuntu 10.10 on it, I've noticed that my hard drive is making a clicking noise. Now this is not a loud clicking noise nor it's constant (only sounds occasionally and when hard disk is not writing or reading anything). Another strange thing is, this only happens when netbook is using battery power, the moment I plug in AC power clicking stops. Additionally I noticed that when I go into BIOS I can hear the click only once, same thing happens if I boot Ubuntu from USB. That led me to believe the problem is within operating system. I did all the surface scans and SMART tests and everything seems to be fine. Now noise sounds like heads are trying to "park" themselves so I tried disabling "spin down" option in Power Management but it didn't help. Any idea?

  • Is it safe to operate a laptop without battery?

    - by leladax
    I know it's 'unsafe' in terms of data loss but I noticed motherboards still have some of their circuits on power when they are plugged in [e.g. a circuit that must wait for power-on signals is certainly one of them]. Hence, I wondered if it would increase the life of the laptop if the battery was simply off. Let alone that may also increase battery life, but that's the least of my concerns. Notice the main point is to plug it off on hibernate and have no power source whatsoever for the duration of being off (apart from the clock battery). (i.e. saving having to plug off the battery every time)

  • Handout export to word from PowerPoint are too big :(

    - by nickjohn
    EDITED i am using power point lectures. i want to mail merge speaker data into the respective lecture. now thats not possible with ppt as far i know, so i have to convert these lectures to handout by using power point option "publishMS word handouts" and use word mail merger. this is good since it will keep the comments/notes added in slides in handouts aswell. but these exported handouts in word remain actual slides and retain link to original ppt rather than simply get exported as images. so the file size gets verrry big 10mb ppt = 212mb doc=88mb docx Is there any option to convert handouts exported from power point to word as images? i simply cant save them as pngs from powerpoint since that will not include the comments data. Thanks
