• 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?

• 3 Monitors 2 different graphic cards

  - by Michael

  I am looking to add a third monitor to my workstation. I currently have 2 monitors connected to a geforce gt 120. 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.

• 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?

• 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.

• 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.

• 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.

• 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?

• Why doesn't C have rotate left/right operators?

  - by icepack

  A bit of a philosophical question, I suppose. Hope it belongs here. C language has the standard set of bit-wise operations, including OR, AND, XOR, SHIFT LEFT/RIGHT, NOT. Anyone has an idea why rotate left/rotate right isn't included in the language? These operators are of the same complexity as other bit-wise operators and normally require a single assembly instruction, like the others. Besides, I can think of a lot of uses for rotate operator, probably not less than, say, xor operator - so it sounds a bit strange to me that they aren't included in C along with the rest. Edit: Please stop suggesting implementations of rotation operators. I know how to do that and it's not what the question about.

• 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

• How can I get data off of a damaged thumb drive?

  - by Lord Torgamus

  A guy I work with just came by to ask me about a damaged thumb drive/USB flash drive. Apparently his son dropped it on a hard surface and it won't power up anymore. They've tried plugging it into multiple machines without success, even though each port they tried was able to power other USB devices. He knows it's not a lost cause because a local tech store is offering to recover the data for $500, but he says they're not worth that much. I figured someone on SU would have an idea about this; he doesn't care about using the drive in the future, just wants to salvage a few files that would be a pain to recreate. Is this possible without advanced equipment, and if so, how? He said he already tried the advice on the Internet about typing in different drive letters and such, but that failed because there was no power going to the drive. He also said that he opened the case up at one point, but I'm not sure what, if anything, he did inside.

• Most Efficient way to set Register to 1 or (-1)

  - by Bob

  I am taking an assembly course now, and the guy who checks our home assignments is a very pedantic old-school optimization freak. For example he deducts 10% if he sees: mov ax, 0 instead of: xor ax,ax even if it's only used once. I am not a complete beginner in assembly programing but I'm not an optimization expert, so I need your help in something (might be a very stupid question but I'll ask anyway): if I need to set a register value to 1 or (-1) is it better to use: mov ax, 1 or do something like: xor ax,ax inc ax I really need a good grade, so I'm trying to get it as optimized as possible. ( I need to optimize both time and code size)

• Computer powers off then tries to start up but resets repeatedly.

  - by Sam Holder

  My machine has started shutting itself off after a few minutes on, everything goes off. A few seconds (3-5) after everything has stopped the lights come back on, the cpu fan and gfx card come on again. They spin for a second, then everything goes off again. A few seconds later same things happens again, light come back on, fans spin for a few seconds then go off. This repeats seemingly forever. If I leave it for a while I can power the machine back on for a while and it will boot again. It will then stay on for a little while again before power off. Rinse and repeat. Is this likely to be power supply or something else? The machine has been up and running for a couple of years before this.

• How do I calculate a good hash code for a list of strings?

  - by Ian Ringrose

  Background: I have a short list of strings. The number of strings is not always the same, but are nearly always of the order of a “handful” In our database will store these strings in a 2nd normalised table These strings are never changed once they are written to the database. We wish to be able to match on these strings quickly in a query without the performance hit of doing lots of joins. So I am thinking of storing a hash code of all these strings in the main table and including it in our index, so the joins are only processed by the database when the hash code matches. So how do I get a good hashcode? I could: Xor the hash codes of all the string together Xor with multiply the result after each string (say by 31) Cat all the string together then get the hashcode Some other way So what do people think? (If you care we are using .NET and SqlServer)

• Computer hangs on start-up, but re-start always works

  - by user10604

  I press the power switch; the fans start whirring; then precisely nothing happens. The monitor lights (I have two monitors) blink to indicate that they aren't receiving any signal - no BIOS splash screen, nothing. This scenario occurs about 80 percent of the time, the other 20 percent being normal starts. Noticing that the computer has not started properly, I press the power switch for four seconds to turn the computer off, and then I press it again to start the computer for the second time. It always starts normally the second time. Always. The power supply is a 750W from SilverStone. The motherboard is a Gigabyte P55A-UD3P. The video card is an Asus EN9800GT. There's 8 GB of RAM. I don't know what other information might be pertinent. Help!

• How to properly set CPU Units for OpenVz VEs

  - by gucki

  According to all the sources I read (openvz wiki, various mailinglists, forums, ..) the values of the cpuunits settings are relative to each other. So when all are equal and the system is busy, all receive the same cpu share. But something still puzzles me with that: why is there a tool "vzcpucheck" which shows "the power of the node/ host": Current CPU utilization: 18000 Power of the node: 880001 Why is there (do I need) an absolute number when all settings are only relative? Shouldn't those two settings result in exactly the same? ve1: 1 ve2: 1 ve3: 1 = 3 ve1: 293334 ve1: 293334 ve1: 293334 = 880001 (power of the node) What's the difference?

• Motherboard or Processor Problem

  - by bradlis7

  My computer is broken, but I'm having trouble narrowing down the issue. I replaced the power supply, because I assumed that was the issue, but it has the same problem. The issue started with my computer starting the fans and running, but it didn't get to the BIOS screen for about 10 seconds. Now it refuses to do anything when the power button is pressed, except when I turn off the machine and take the processor out for 10-20 seconds, then put it back in, I came hit the power button immediately, and the fans start for 1/2 second, and quit. Does this sound like a is a processor or motherboard issue? I removed all components, so I know that the issue is with one of these two things.
