• Second portable monitor for a laptop

  - by user2630

  I'm away from my home office fairly regularly but I find it difficult to really settle to productive coding without my custom 4-screen custom built PC. My laptop (a slightly ageing HP Pavilion with a 1440 x 900 display) would really benefit from a portable monitor to plug into the vga port. Is there any suitable products out there which offer an easily luggable lightweight monitor which would fit in my laptop, offer reasonable resolution and response, and significantly enhance my screen real-estate?

• Compaq Presario CQ40 unexpected turn off

  - by CRoshanLG

  My Compaq Presario CQ40 (yeah, its pretty old) suddenly turns off after about 1/2 - 1 hour usage without any notice or warning. The power cable and adapter works fine (indicator bulbs show that power is given to the laptop), but it seems like machine suddenly plugged off from the power source. And when I try to switch it on, after the sudden turn off it simply won't turn on. I can only turn it on after letting it to rest for at least couple of hours! ** The battery has been dead for some time now, but it has been working fine on direct power supply until recently. Has anyone encountered this? and hopefully knows any cure?

• I just moved, have no internet on my laptop or ipod, but everyone else who lives here does

  - by Kay

  I just moved to Thunder Bay and my laptop as well as my ipod cannot connect to the internet. My laptop allows me to write the password for the wifi, but I still have no internet connection. When I try to use the cable, the computer tells me I have a perfect connection, even the icon shows that it's working, but I can't open any web pages or use any internet functions. When I try to use MSN it sends me to a troubleshooting option and informs me that there's some kind of problem with the "gateway". I have unplugged the modem and the router and plugged them back in, this did not help. I am living in a home where all the people are using wifi on the same system as me, and no one has ever had any problems. Back home both my laptop and my ipod worked without a problem both in my home, as well as on campus. Since this problem seems to be limited only to me, it would indicate that there's a problem on my end -- with my laptop. However, in that case my ipod would be working. It has never failed to connect before. Any suggestions would be much appreciated.

• laptop motherboard "shorts" when connected to adapter

  - by Bash

  Disclaimer: I'm sort of a noob, and this is a long post. Thank you all in advance! summary: completely dead laptop with no signs of life whatsoever (suddenly, for no apparent reason) Here's the deal: Lenovo Y470 (only a few months old with no water or shock damage). It stopped working suddenly (no lights, no sound, even when connecting adapter with or without battery). I tried a different adapter (same electrical rating), but no luck. I disassembled the thing completely, and tried plugging in the adapter and looking for signs of life with all different combinations of components installed (tried all combinations of RAM, CPU, USB power cords, screen, etc plugged in). no luck. Then, I noticed (as I was plugging in the adapter to try for the millionth time) that there was a "spark" for an instant when I first connect the adapter to the power jack. The adapter's LED would then flash (indicating it isn't working or charging). So, I thought the power jack has a short of some sort (due to bad soldering or something). Scanned virtually every single component on the motherboard, and tested the power jack connections with a multimeter. No shorts or damage to anything on the entire motherboard. Now I'm thinking I need to replace the motherboard. But, my actual question: What does this "shorting" when connecting the adapter signify? (btw, the voltage across the power connections and current through it drop to virtually zero when the adapter is connected and "sparks", and they stay that way). The bewildering thing is that there are no damaged components, and the voltage across adapter terminals returns to normal after I disconnect it (so it's not damaged). Please take a look at the pictures (of the motherboard's power connection and nearby components) and see if I'm missing something completely obvious...

• Laptop recommendation - Portable Gaming

  - by ivan

  So, I'm looking for a new laptop (http://superuser.com/questions/116869/toshiba-satellite-u500-totally-damaged-lcd). My requirements for a new Laptop are: -good keyboard(illuminated) and touchpad (multi-media keys included, should be better than toshiba u500) -good graphics card, with system rating of 6.3 and up for gaming graphics (my Toshiba U500 has 6.3). I used to run some heavy games on my Toshiba U500 with ATI Mobility Radeon 4570 with 512 mb VRAM but the framerates are not that nice on high settings. -Decent CPU but I think all new Core i3, i5, i7 can run most of recent resource intensive games (My Toshiba U500 has a Core 2 Duo T6500, 2.13 Ghz) I'm also looking for a long-term reliability, good sound quality, lots of fast RAM of-course(4GB DDR3 - 1066Mhz and up) and a clear looking LED screen with a decent resolution. (I can accomodate a laptop with screen size of 13-inch upto 15.6 inch, and I don't want it to be heavy because I might be taking it outdoors) I'm actually impressed when I saw HP Pavilion DV6t but the screen resolution seems to be a little too small for 15.6 inch. The Pavilion DV3 are also good but I want to know if there other options. Looking for some opinions.. Thanks. :D

• Ungrounded laptop (Macbook Pro) buzzes in headphones, weird feeling when fingers brush lightly

  - by donut

  I've got a nearly 3-year-old MacBook Pro 15" 2.16GHz (MacBookPro2,2). When I have am not using the extended, grounded adapter for the power supply, just using the simple, two-prong plug I can hear a buzzing when I use very sensitive earbuds. This goes away if I touch a metal part of the laptop. Also, I can feel a weird, fuzzy feeling when I brush the metal parts of the laptop lightly with my fingers/skin. Somewhat similar to feeling of a touching hair or a balloon that's charged with static electricity. But I'm not getting sparks or anything. And if I'm touching a metal part of my laptop solidly (not just brushing it) and then I touch someone else's skin I can feel the same effect and so can my victim. I've noticed similar effects with an ungrounded electric blanket. But with that the buzzing can be easily heard without headphones. Is this a defect, normal, or something else? And what exactly is happening?

• Closing laptop lid and using external display causes mouse to move on it's own

  - by PolishHurricane

  I plugged my ASUS Taichi Laptop into an external monitor via the VGA Adapter that it comes with. It was working fine, but then I configured a power option so I could shut the lid without it going to sleep (so I could use just the external monitor with an external keyboard/mouse). Problem is though, now, when the lid is closed and I move the mouse, the mouse is moving around on it's own, but when I open the laptop lid back up, the mouse is fine. I looked under the lid when it was closed and the display properly shuts off on the laptop. It's not the external mouse/keyboard because I completely unplugged them and it was still happening. Nobody is hacking me or anything, I totally went into airplane mode/pulled the wire. I have a touchscreen, but I put a piece of paper over it and it wasn't doing it. I was thinking it might be the trackpad being touched somehow by the screen when the lid is closed? But I went into windows 8 control panel options and I couldn't find anywhere to disable it (it sees the USB mouse I think).

• HP G61 Laptop wont boot- display stays off, caps and num lock indicators blink repeatedly

  - by Benguy12

  I had my HP G61 laptop running in sleep for a while. When I came back to it about a half-hour later, it was no longer in sleep mode - the power light and the Wi-Fi indicator light were on (I keep Wi-Fi off becuase I use a wired connection) - but nothing was showing on screen. In fact, the display wasn't even turned on. So I let it sit for about 10 minutes but nothing happened. I did a force shut down and rebooted. Instead of a normal boot, the display didnt turn on, the Wi-Fi indicator was off, and the Caps Lock and Num Lock lights just blinked repeatedly. On the external keyboard i use, none of the light indicators were blinking or even on. I tried force shut-down again 10 times, then unplugged all connections except for the power cable (my laptop battery dosent hold a charge for more than 2 minutes, so I always must have a wall connection) and tried to boot again but still nothing happened. I unplugged the battery and even then nothing happened. I also tried booting with the disk drive open, and then with it closed again. On the time it was closed, I was able to successfully boot into Windows, but recieved a "Windows did not shut-down sucessfully" notice. Does anybody know why this may have happened? My PC's specs: Windows 7 Home Premium, 64-bit 4GB of physical RAM, 8GB of vRAM (on a flash drive) AMD Vision x64 processor (don't know any other specs about it) ATI Radeon graphics card, 392 MB DVD-R/W lightscribe drive 2 External hard-disks (first one is 1.5TB, second one is 1TB) custom boot-screen and boot-annimation Standard BIOS apps running before sleep: firefox 10.4 itunes 10.6 adobe photoshop extended CS5.1 rockstar games social club (running in background) microsoft powerpoint 2010 professional edition google chrome I was NOT running Aero or any fancy themes - I was using the normal windows classic theme. I have a desktop icon manager application called Stardock Fences that was also running (it runs as a service/process).

• Laptop Most Likely to Have Good Driver Support

  - by ShabbyDoo

  Through numerous bad experiences, I have learned that the most likely cause of laptop "failure" is the lack of updated drivers for new operating systems. As an example, I have a perfectly good Thinkpad T42 at home which runs Windows 7 just fine for my purposes except that no compatible ATI video drivers are available, and the generic drivers have flicker effects. I recently saw an ASUS laptop which looked quite nice except that I would be beholden to them to release ATI video driver updates customized for it. And, I can't trust them to do that for more than six months. What laptops (manufacturer/line) should I consider so that I could expect at least a couple years of frequent updates? I plan on running Windows 7 and installing whatever successor comes out. I like Intel components (especially WiFi) because I can install their drivers directly from them, and they have a long history of providing updates for years after shipping a particular component. More generally, components from companies which are likely to update drivers frequently are good as long as I can install the component manufacturer-provided drivers without laptop-specific customization (like the ATI drivers). Also, if a component can be replaced easily, I am less concerned. For example, Dell stopped pumping out updated drivers for one of its mini-PCI WiFi cards. The solution was to buy an Intel replacement on eBay for $12! That's fine. I can deal with that. So, what laptops should I consider so that I'm not likely to be stuck between a rock and a hard place?

• Re-installing Windows on an old laptop

  - by Khaled

  I have an old laptop and I want to re-install Windows XP on it. The problem is that this laptop does not have an optical drive. I checked the boot sequence in the BIOS. It does not show an option to boot from USB. It have only two options: Boot from HD. Boot using Realtek agent (network boot). I tried to copy the Windows CD to second drive D:\ and run the installed from there. However, I could not format the C:\ drive. Windows complaints about setup files will be removed or something like that. I tried to boot the laptop using PXE, but I could not. It seems that the DHCP request did not get answered. I thought I could use a USB CD-ROM drive (I don't have one to try), but it might not work as there is no option to boot from USB. Do you think it will work? Do I have other options to try? Any recommendations?

• HP Laptop recognizes hard drive just long enough to install windows

  - by Joe

  I have an HP laptop, DV6500 (CTO). It refused to boot one day, so I ran some diagnostics (a friend lent me "Hirens Boot Disk", "UBCD" and "PC DR 6"). Everything passed, except for the hdd. I replaced the HDD with a used drive of unknown condition. Installed windows with no problems. Installed the wireless driver, tried to reboot ... no luck. So I went to Best Buy, bought a brand new Western Digital 320gb HDD. Put it in the machine, installed windows (vista home premium). Installed the wired networking driver. Tried to reboot. No luck. Put the first hdd back in the machine, reinstalled windows. Started to install some drivers, went to reboot, and the machine won't come back to life. Put the second hdd in the machine, rinse wash and repeat. I've replaced the memory, even though it passed diagnostics. Problem exists with both brand new memory, and old memory. The BIOS recognizes the hard drive. The computer freezes directly after the bios splash screen, and there is no hard drive activity light. I've tried two linux live distros (gentoo and ubuntu). Neither would run on this laptop, but will on a different HP laptop. UBCD and Hirens Boot Disk both ran, as did PC Doctor 6 which refuses to test anything (gets stuck at "enumerating hard disks"). Is there anything else I can try?

• Laptop freezing every few seconds, including screen + sound

  - by zenstealth

  Just a few days ago, my Windows 7 HP dv4170us (1.76Ghz CPU, 1GB Ram) laptop started to freeze every other second where everything on screen and and sound (such as a song playing in iTunes) would just freeze until I bash it violently (without actually breaking the laptop) or wait for a couple of more seconds. I think it started one night when I noticed that a USB mouse of mine stopped working, and it displayed random "Device was not recognized" errors. I just unplugged the mouse and ignored it. Skip forward to the next day, is started freezing, and as of today I can't get my computer to not keep freezing. I tried to backup my files onto an external hdd, but it almost corrupted the drive. I ran 4 complete virus scans using MSSE and MalwareBytes (both quick and full scans), and they all came up clean. In the Task manager, the CPU usage is on a constant max, and so is the RAM (if I have just a few apps running, I only have like 30Mb of free RAM left). Also, on the outside of my laptop, right above where the CPU is located, it's very, very hot. I suspect that something is wrong internally within inside of the computer, but I'm not sure. It also does the same thing when booted into Ubuntu.Does anyone know what could be wrong with it?

• My laptop screen keeps dimming

  - by Rowland

  I have a Cryo laptop with Windows 7 installed, bought in December 2011. Sometimes the screen seems to persistently dim and/or brighten up, even as I am doing things. In fact the brightness is varying even as I type this. The battery is always fully charged and connected to the mains. I have checked many times the battery/power-saving settings always leaving the settings the same way; full brightness and never dimming when on the mains. Yet when the screen starts playing up I can end up with the screen dimming and brightening almost continuously. I once went to the "adjust screen brightness" window when the screen had dimmed. I found the brightness slider on 100% (as I expected) but, as I dragged it to the left, to dim the screen, it first brightened and then started dimming, i.e. the screen setting said 100% brightness but it was only at, maybe 80%. I have checked with Cryo and they just say check the power settings. I know what these are and how to work them and always set them to never dim/full brightness, yet still my laptop starts this dimming every so often.

• Laptop CPU fan not working properly

  - by Smith

  My laptop's CPU fan is suddenly acting very bizarre, and I am at a loss for what to do so I am asking for some help. Specifically, the fan is not even starting to spin until the CPU reaches 60 degrees Celsius (checked through HWmonitor). Once it is on, however, it properly stays on even when the CPU gets back to idle temps around 38 Celsius. Before, the fan was simply starting with the computer and staying on like normal. I've checked this for consistency both by allowing cold boots to ramp up temperature to 60 Celsius (the slow climb also causing the laptop to become unreasonably warm near the heatsink), and also running Prime95 immediately to kickstart the fan (this works every time). The fan seems to be stationary when turning the computer on from either sleep or shutdown. The fan will start at POST very briefly, and then stop completely. I've checked the BIOS for a SmartFan setting but haven't found any. I've opened the case to check for dust or debris and have not found anything (I applied some canned air to the area just in case). The laptop is a Lenovo ThinkPad Edge E430 and the CPU is an Intel Core i5 3210m @ 2.5 GHz. Any advice would really be appreciated.

• A list of 'best practices' for extending the life between charges of a notebook battery.

  - by Tim Visher

  Hello Everyone, I'd like to compile a list of best practices for getting the most out of a single charge of a typical notebook battery (be it Li-Ion or Li-Poly). Sources would be great as well. I've heard, for instance, that the best things to do to improve battery performance (not the total lifetime of the battery, just single charge performance) are, in descending order of effectiveness: Turn your display all the way down. Turn off WiFi Turn off Bluetooth Spin down disks when they're not in use. etc… I'd like to get sources together for these and other tips for extending life-between-charge for any battery on any notebook (as these really are all about Demand Management rather than Life lime extension. Thanks!

• Is it save to configure "Shutdown" on "When laptop lid is closed" ?

  - by Takkat

  To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

• Ideal laptop specs for a Computer Science Masters student? [closed]

  - by Ayush

  I have a HP pavillion core 2 duo 2 GHz and 4 GB RAM, and it is painful to use this machine for any kind of coding. Eclipse (especially Juno) literally takes 5 minutes to load. And even after that, everything is lagy. Apart from school stuff, I also use my computer as a television. I watch Hulu, Netflix, YouTube etc in 720p, and this laptop gets hot as hell and the fans are loud enough to wake somebody up from deep sleep. I DON'T use my laptop for Gaming or Video/Photo Editing. I'm looking to buy a new laptop (in which most widely used IDEs would work smoothly and playing hi-def videos wouldn't be too much for the machine to handle) any suggestions (on hardware specs) would be greatly appreciated. Thanks

• AMD processors witn graphics card bundled [closed]

  - by shybovycha

  Sorry for posting this question here - just don't know to which StackExchange website i should be writing. I've heard AMD created processors with video card bundled. So now these processors should work as fast as just usual processors with discrete video card but AMD's ones should use less power and spread less warm. Some googling around gave me the result like "AMD processors of A-series". They were mentioned to be build using that technology i described above. But on the other hand, we have a small rate of publishing and not-very-good quality of AMD drivers. I am a game-developer and web-developer so i need a powerful processor and graphics card and a lot of RAM on board (to make it possible to create a sample Grails application, for example or to create some 3D models in Maya/Cinema4D, for instance). Still i want my battery to be a long-living one, so power usage is a bit critical for me. So, my questions are: are there any processor building technology like i've described and which series they are (if they exist)? which processor shall fit the laptop the best: AMD one or i5/i7 on with nVidia graphics card for the purposes mentioned above?

• Supplementary Developer Laptop

  - by David Smith

  I'm looking to buy a laptop with the following specs for a developer. The goal will be to have a development machine supplementing the devs desktop. During work hours the dev will be on a beefy desktop. For working while on the go: trains, client sites, code camps, it would be nice to have a machine which can run Visual Studio 2008 without needing to remote desktop into their primary machine. What do you think is the lowest cost laptop meeting this need? Here are the specs I have in mind: SSD drive 64GB-doesn't need to be huge, most data is stored on servers. Will need to fit Windows 7, IIS, SQL Server, and Visual Studio 2010. RAM-3GB processor =Pentium Core 2 duo Screen size = 14 inches. OS doesn't matter. It will be paved with Windows 7 Ultimate optical drive omitted would be a plus. weight and battery life aren't so important because the machine will be plugged in almost all the time.

• replace laptop hard disk

  - by 5YrsLaterDBA

  I have bought a ACER Aspire 5736Z-4790 laptop for my parents. It just passed the warranty. I think the hard disk is bad now. I cannot open/copy some of my files. It will crash (blue screen) when I do chkdsk /f/r in the stage 4 of 5 which is verifying file data. I can hear a strange noise when it is reading the bad sectors (I guess because it hangs there.) I am thinking replace the hard disk. should I buy the same hard disk or any SATA laptop hard disk will be ok? BTW, is there a way to repair it (with software)?

• Connecting desktop computer to the internet through laptop wifi

  - by Josh

  Due to some home network complications I have had to move my router to a seperate part of the house, therefore the wired network I had set up can no longer work. Before I find the time to go out and buy a Wifi adapter for my desktop PC, I have a laptop that uses a built in Wifi card to connect to my router and this can connect to the internet, and I was wondering if I could somehow access the internet on my desktop PC via my laptop. I'm hoping for a not-so-complex solution as this will only be set up for a few days, but it is quite vital that my desktop computer gets internet access. Does anyone have experience in this sort of thing and can help me out? Thanks.

• Laptop as server [closed]

  - by Parhs

  My client wants to use a cheap AMD E-300 ,5400 rpm disk,4gb memory laptop as a POS server and music player at the same time with dual screen. I couldnt convince him that this wouldnt be a good choice. The applications are a database a music player ,and the .net 4 application. I am afraid of performance issues. However the reasons for this choice is that laptop takes not much space ,easy dual screen for music player and application ,can easilly be replaced and that it will last forever as none of his laptops are ever broken. I believe that this is a good idea but i feel thats something wrong there. Do you believe that is an ok choice?
