  • toshiba a200 laptop hangs/freezes when plugged in

    - by tapan
    The subject says it all. It is the exact same problem as described here. I had asked a similar question before here. My system specs etc, everything is here. My problem is just that I cannot afford to get it fixed right now. I just need for the laptop to be kind of usable for 2-3 more months. It worked perfectly for 3 months or so in ubuntu recovery mode. Now it hangs/freezes every hour. I spend 8 hours a day on an average on my laptop. So i just want it to last at least that long. If the laptop is not plugged in in recovery mode / regular ubuntu mode, it freezes in 5 mins and the screen becomes all weird. With my windows 7 OS, it works perfectly on battery but hangs instantly as soon as it is plugged in. Also now, a high cpu usage doesn't help anymore. Any strategy or suggestions i could employ to extend the duration for which it doesn't freeze ?

  • New harddrives failing within weeks.

    - by Jason Kealey
    I've experienced 8 hard disk failures in 3 months and have tried many things to solve the issue permanently but I have failed. I would like to know if you have any advice for me. System was running Win XP on an Asus P5W-DH Deluxe. I have setup a RAID-1 array. I started out with 2 x 500 GB 7200RPM Western Digital drives. One died. I took it out to RMA it. On the same day, the router was fried. Assumed a power surge occurred; connected an older UPS to protect the system. Once I got my hands on an identical disk, I installed it. The RAID array was rebuilt. A few days later, the other one died. Assumed the rebuild caused it to fail. Took it out for RMA. Before the other one arrived, the remaining one died. I then discovered I could re-enable them using the Intel Matrix Storage Manager. I re-enabled both and the system seemed fine for a week, until both died again. I got two new 1.5 TB 7200RPM Seagate drives and re-installed Windows 7. Also replaced the UPS and power supply. They both died again. The voltage on the plug is stable between 120 and 122V as per the UPS. None of the other devices have had any problems (monitors, etc.). At this point, I see two options: a) electrical issue in the house that was, for some reason, not blocked by the UPS. b) something else inside the system causing surges? motherboard? onboard raid controller? Failures happen fairly quickly, between 2 and 14 days after I fix the previous issue. I just gotten a new computer (Core i7) to replace it. If it is stable, I can determine that b) was the problem. If it fries its hard drive again, I can determine that it is an electrical issue in the house. Do you have any other thoughts? Any tools I can run on the drives that failed to get more information about the original SMART event history?

  • Evaluate a vendor laptop before deployment to user?

    - by NetWarrior
    I get numerous requests from executives and users for new smaller laptops for travel purposes. Most of my evaluation is based upon whether or not it can run certain applications. Mainly lotus notes, office, and video. Most of the laptops include windows 7 OS, and are fully loaded with ram, a high-end processor and a integrated graphics card. My boss whats me to document the usefulness of the laptop and performance. I'm just a little confused on how to setup a document that can be used by members of the IT department for future evaluations.

  • HDD not detected whenever first power on (detected at BIOS level)

    - by Alvin Lim
    I am using Asus P8H61-M LX Motherboard with latest version of BIOS: 4401 One SATA-3 Western Digital Black Series 1.5TB is attached to SATA port 0 A Samsung 22x DVDRW SATA drive attached to SATA Port 1. ps/2 Logitech mouse and keyboard. CPU is i3 with DDR3 8Gb RAM. no other devices are installed. My problem is that when I turn on the computer, the WD HDD is not detected. ie cannot be booted. I have to press ctrl+alt+del in order to get it detected. I'd used the WD data lifeguard software to scan the HDD, the smart status is OK, the surface scan does not show any error at all. Where did I do wrong? Any advice is greatly appreciated.

  • How long until the chirping stops or what can I do to make it stop?

    - by MadBurn
    I know computers, I have been fixing them and building them for over a decade... but I don't know the exact electronics of them. My personal desktop PC is making an irregular, but constant, extremely high pitched chirping noise. I know this could be my hard drive, but I've heard that noise before and I believe this is a capacitor or part of the electronics. This noise is right at the edge of my hearing and I can feel it more than I can hear it. After a while, it starts to give me a headache and makes me physically sick. How long will this last? Is there anything I can do to fix it (short of replacing the entire motherboard)?

  • Complete machine freezes...at a loss

    - by user28818
    Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

  • what's POST code 18 / can I run an ASRock P55 Pro + Core i3 530?

    - by Michael Borgwardt
    When I switch my newly built PC on, the fans start up, but I get nothing on the monitor, and the POST display on the motherboard runs quickly through various codes and then stops at code 18, which does not appear in the manual (the list there seems identical to this one). This lasts about 10 seconds, after which the machine shuts down. After a pause (also about 10 seconds) it starts up again, and this repeats until I cut the power. Interestingly, when I push the reset button, it stops at POST code 16 (which is also not listed in the manual). Does anyone have information about the meaning of those codes? Motherboard: ASRock P55 Pro CPU: Intel Core i3 530 Graphics Card: Sapphire HHD 5750 Does anyone have experience with that Motherboard/CPU combination? It says on the packaging and in the manual that it's only compatible with Core i5 and i7 (no mention of i3), but on the maker's product page, the i3 is listed as compatible as well.

  • HP Pavillion dv6 laptop - 15 beeps on startup and a black screen?

    - by dunc
    Usual story - girlfriend's step-brother's laptop is broken. I don't know a huge amount about what occurred before it broke, but I do know the following: When you try to turn the laptop on, it beeps 15 times exactly. The screen remains black. The LED on the Caps Lock key flashes continuously. If left on, the laptop never boots - as far as I can see. If left on, on a stable surface with decent ventilation for a relatively short period of time, the laptop (below keyboard, but not where the RAM/HDD are) gets very hot. I've tried doing what most websites appear to recommend for similar problems, which is to disconnect AC and battery then hold the power button down for a minute before reconnecting the AC and trying to turn the laptop on - no difference. EDIT I've also tried re-seating the RAM, to no avail. Any ideas? Thanks in advance,

  • How can I get multiple video cards to work on linux?

    - by user17943
    I installed fedora 12. I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card. What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it. Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc.. I would probably have no problem following the documentation & editing the file if I knew a good way to find these values. Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long. Thanks

  • Shopping for a very compact and powerful workstation [closed]

    - by qdot
    I'm on the market for something small, size of an Mac Mini, could be heavier, that packs a lot of compute power - goal is to have a fast, known development machine at customer's site, but still easier to fly with than desktop-replacement laptops. If Mac Mini came with a quad-core i7, it would be my likely choice. Any other manufacturers to look at? Or perhaps a Mini can be upgraded beyond official specs?

  • Laptop powering off after 10 mins or so

    - by Jack
    I have no OS installed, and I am trying to use a linux boot disc. However it is not a linux problem....if I just leave the computer on at the no operating system found message, it still turns off. I thought maybe it was overheating, but I am 90% sure that is not the problem. What else could cause this? I should have mentioned, it's a laptop.

  • Microsoft Wireless Keyboard 3000 v2.0 not working, but paired Wireless Mouse 5000 on same receiver does?

    - by John Straka
    I have a Microsoft Wireless Keyboard 3000 v2.0 that was bought paired with a Microsoft Wireless Mouse 5000. They're both Bluetooth and use the same receiver. The keyboard no longer works. The receiver is fine, as the mouse still works. The keyboard is still detected by Windows when the receiver is plugged in. The batteries have been replaced. There are no on/off switches on the keyboard or mouse, and no re-sync button on them or the receiver. Results are the same when using the receiver in a different USB port, or on a different machine. Anything else I might try to fix this, or should I hold a funeral for the keyboard?

  • Audio switch with multiple 3.5mm input & outputs

    - by David Nguyen
    I've been searching for a device that simple allows me to pick one input and one output from multiple input/outputs. I thought this would be a called a switch but I can only find ones with one input. Is there such a device that can do this? I will be attaching various devices, i.e. multiple console sound, PC & Laptop inputs and outputting to my speakers or headphones. I'm looking for something small and simple. All inputs and outputs are 3.5mm.

  • USB port causing device problems after new motherboard upgrade

    - by enbuyukfener
    I'm looking into a PC with an issue with one of the front USB ports (perhaps both). It was working before a motherboard upgrade but since then, a USB drive was inserted, overheated and does not appear to be working. Then a phone (with USB charging) was plugged in, and the phone OS suspended. Removing and re-inserting the battery led to the phone (and hence battery) working, however the battery no longer charges (including with a wall charger). It seems too much to be a coincidence and am wondering what the issue may be? Ideas so far are short circuiting, or over-current to the USB ports. Note: Did not occur to me, so details are not 100% accurate or complete. Feel free to ask for missing info that I may have forgotten though.

  • Computer only booting after POWER ON/OFF 10 times or more?

    - by Jan Gressmann
    Hi fellow geeks, recently my computer started to behave like an old car and won't start up anymore unless I flip the power switch repeatedly. What happens when I power it on: CPU fans spins briefly and very slowly, then it stops Same with GPU fan No BIOS beeps or HDD activity Screen stays black After turning it on and off for like 10 times, it'll eventually boot like normal and run smooth without any problems what-so-ever. But I'm worried it might eventually die completely. Anyone know the most common cause of this? Maybe I should just leave the computer powered on? :)

  • Can I charge USB devices from a powered hub that isn't connected to a PC?

    - by Anodyne
    This will probably sound familiar to most of you... In my home, we have a whole bunch of devices that can be charged via USB (two iPhones, a BlackBerry, an iPod Touch, etc ad nauseam). We also have a bunch of USB chargers, each of which has a single USB port on it. I'd like to have something permanently connected to AC power with at least 4 USB ports on it, so we can just plug devices in and don't need to go looking for a free outlet. So here's the question: if I buy a powered USB hub, will that do the job even if I don't connect it to a PC? Ideally if you have a hub that you can personally verify will be suitable, let me know the manufacturer and model :-) Thanks in advance! EDIT: The solution I eventually went for was this: Kensington 4-Port USB Charger for Mobile Devices (Europe) There's also a US version here: Kensington 4-Port USB Charger for Mobile Devices (USA) It arrived yesterday, so I used it to charge the following devices, all at the same time, overnight last night: 32GB iPhone 3GS 16GB iPhone 3G First-generation iPod Touch Kensington Portable Power Pack for Mobile Devices I can't say anything about the charging speed (as I left it overnight) but all devices were fully charged this morning.

  • How is fire spread in server rooms and datacenters?

    - by sharptooth
    Every now and then I read that a severe fire has happened in some datacenter, lots of equipment has been damaged and customers have gone offline. Now I wonder what is there to support and spread fire? I mean walls in a server room usually have little or no finish. Racks are made of metal. Almost all units have metal cases. Cables have (or at least should have) insulation of materials that don't spread fire. What is spreading fire in a server room or datacenter?

  • PC has a mind of it's own.

    - by ULTRA_POROV
    When I put my PC into standby, sometimes it randomly awakes, scaring me and waking me up. What could be causing this. No it is not my mouse moving, it can only be powered back on by the power button. It's really strange.
