  • Possible to bypass laptop inverter power source - HP dv5000 inverter 7 input pins?

    - by Glen Tankersley
    I've got an HP dv5000 laptop with a backlight that won't light up, (but is known to be good). I've also got an inverter board which is good, but isn't getting power from the mobo. So, my question is, would it be possible to bypass the original power source, and hack together some type of externally powered input just for the backlight? If so, does anybody know the input voltage and meaning for the 7 input pins for the inverter board, or how to find out?

  • Wondering about the Windows 7 serial number my laptop has, and its uses.

    - by overmann
    So that's the serial number of my pre-installed windows copy, I take it. But am I allowed to use it again when, say, I don't know, my system gets crippled by a sneaky virus? If I format my computer and install windows starter again from a USB drive (speculating. I've never format before, I suppose is completely possible) Is that serial number still valid? I'm talking about the number printed on the back of my laptop.

  • My new laptop - with a really nice battery option

    - by Rob Farley
    It was about time I got a new laptop, and so I made a phone-call to Dell to discuss my options. I decided not to get an SSD from them, because I’d rather choose one myself – the sales guy tells me that changing the HD doesn’t void my warranty, so that’s good (incidentally, I’d love to hear people’s recommendations for which SSD to get for my laptop). Unfortunately this machine only has one HD slot, but I figure that I’ll put lots of stuff onto external disks anyway. The machine I got was a Dell Studio XPS 16. It’s red (which suits my company), but also has the Intel® Core™ i7-820QM Processor, which is 4 Cores/8 Threads. Makes for a pretty Task Manager, but nothing like the one I saw at SQLBits last year (at 96 cores), or the one that my good friend James Rowland-Jones writes about here. But the reason for this post is actually something in the software that comes with the machine – you know, the stuff that most people uninstall at the earliest opportunity. I had just reinstalled the operating system, and was going through the utilities to get the drivers up-to-date, when I noticed that one of Dell applications included an option to disable battery charging. So I installed it. And sure enough, I can tell the battery not to charge now. Clearly Dell see it as a temporary option, and one that’s designed for when you’re on a plane. But for me, I most often use my laptop with the power plugged in, which means I don’t need to have my battery continually topping itself up. So I really love this option, but I feel like it could go a little further. I’d like “Not Charging” to be the default option, and let me set it when I want to charge it (which should theoretically make my battery last longer). I also intend to work out how this option works, so that I can script it and put it into my StartUp options (so it can be the Default setting). Actually – if someone has already worked this out and can tell me what it does, then please feel free to let me know. Even better would be an external switch. I had a switch on my old laptop (a Dell Latitude) for WiFi, so that I could turn that off before I turned on the computer (this laptop doesn’t give me that option – no physical switch for flight mode). I guess it just means I’ll get used to leaving the WiFi off by default, and turning it on when I want it – might save myself some battery power that way too. Soon I’ll need to take the plunge and sync my iPhone with the new laptop. I’m a little worried that I might lose something – Apple’s messages about how my stuff will be wiped and replaced with what’s on the PC doesn’t fill me with confidence, as it’s a new PC that doesn’t have stuff on it. But having a new machine is definitely a nice experience, and one that I can recommend. I’m sure when I get around to buying an SSD I’ll feel like it’s shiny and new all over again!

  • Laptop monitor stopped working and can't be re-enabled on a Dell Latitude E6410

    - by xektrum
    I'm using Ubuntu 12.04 (upgraded from 11.10), everything seemed to work fine until today when my laptop monitor suddenly stopped working. Here are the facts: My laptop is a Dell Latitude E6410, Intel graphics. External Monitor is attached through a docking station. Everything worked fine for about 6-7 month, then upgraded to 12.04 Issue started today after a week of upgrade. I think the issue started after I ran CounterStrike 1.6, both monitors blinked and then only the attached monitor which is connected to a docking station continued to work I thought at first that was a transient issue but then I've rebooted, removed the battery but the same happens. Laptop Monitor and external monitor work fine up to login screen, but after I login it goes black Whenever I try to re-enable laptop monitor from Display Manager I get errors: The selected configuration for displays could not be applied could not set the configuration for CRTC 63 Not sure what technical details are required but here are some: $ xrandr Screen 0: minimum 320 x 200, current 3120 x 1050, maximum 8192 x 8192 eDP1 connected (normal left inverted right x axis y axis) 1440x900 60.0 + 40.0 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) $ tail /var/log/Xorg.0.log [ 8367.132] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.132] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.174] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.174] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.174] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.174] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.265] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.265] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.265] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.265] (WW) intel(0): Page flip failed: Device or resource busy I'm using gnome-shell, and the only ways I've been able to get both display working have been: 1) Booting with laptop disconnected from docking and then re attach external with VGA instead of DVI, but only worked for a session. 2) Removing xserver-xorg-video-intel, but then I gnome-shell is gone as well as dri I would appreciate any suggestions. Regards, ============================= WORKAROUND FOUND ============================= So I have tried few things and here is what worked: I've installed a newer version of xserver-xorg-video-intel (2.19 vs 2.17) from ppa:xorg-edgers/ppa, it didn't work at first, it was only showing low graphics mode, so I tried with a different linux-image 3.0.0-19-generic-pae instead of 3.2.0-24-generic-pae, which I believe is 12.04 precise default, then everything started to work again, Now I've installed 3.4.0-1-generic-pae from same ppa and everything goes flawless so I believe the issue is either with linux-image 3.0.0-19-generic-pae or xserver-xorg-video-intel 2.17. Hope this helps someone in the future.

  • How do I know my laptop is 64 bit compatible?

  • Ubuntu is booting on acer e1-510 laptop, but screen displays nothing

    - by user287602
    Tried loading ubuntu 12.04 (32-bit as well 64 bit) through bootable usb , on a brand new 64-bit acer E1-510 laptop. It shows the 'Try ubuntu without installing screen' and I selected that option. But instead of showing ubuntu's logo(which implies it is loading). I get a blank screen. The screen is on, but it shows nothing. I tried the same on an old model laptop acer aspire 5738 and it worked like a charm. However, I realized that Ubuntu is actually booting on E1-510 and only the display is not working. How did I arrive at this conclusion? When I select on 'Try ubuntu without installing screen', after about 8-10 seconds I see that the WiFi indicator light on the laptop panel switches on(just like when we boot up a Windows OS or even Ubuntu ). I got an idea that the system booted Ubuntu. To confirm this, I tried to adjust volume using keyboard shortcuts. Voila, I can hear the sound of adjusting volume! That means it has already booted Ubuntu. I confirmed this with another step. I pressed the power button once and after two seconds I pressed ENTER. It began the process of switching off and within 5 seconds the laptop was powered off. You may ask, Why is this a confirmation that Ubuntu has booted? This is because in Ubuntu when you press on power button, a dialog box opens with shut down, restart, suspend option- and the shut down option is already selected by default; so all I have to do is press ENTER to shut down. This again proved that Ubuntu was indeed up and running. Unlike previous 'AskUbunutu' posts about Acer e1-510, I must mention that my laptop came WITH the Legacy BIOS mode, so its not really a problem to boot ubuntu from a bootable pendrive. Only the screen is not working. In case you need to know, I am running Windows 7-Ultimate 64 bit on acer e1-510.

  • Share laptop's Wi-Fi with a LAN connection and a mobile device

    - by xperator
    OS: Windows 7 64bit I want to share my laptop's internet connection between my PC and my Android device. But I can only do one of them at a time. The laptop is connected to internet wirelessly. The PC is connected to the laptop using a Ethernet cable and internet is shared between them. I want to connect my mobile device to my laptop by making the laptop into a Wi-Fi hotspot. PC (Ethernet) == Laptop (connected to net by Wi-Fi) <== Mobile device (Wi-Fi hotspot) I have 3 connections in my laptop: Wireless Network Connection (internet - shared) Local area connection (PC) Wireless Network Connection 2 (Wi-Fi hotspot) Every time I have to disable either the LAN to get the Wi-Fi hotspot working, or disable the Wi-Fi hotspot to get LAN working. How can I share so I can use both at the same time?

  • Which linux distro for a laptop in windows environmet?

    - by Dev er dev
    I just got new laptop at work. What would you recommend as a linux distribution for it? All other developers are working under windows, and use windows tools. I'm currently using ArchLinux, but want to change it. I don't want to waste time configuring wireless, windows network shares, network pritners, projector, etc ... I want this stuff to just work, while still having sane and stable development evironment and tools. Is Ubuntu a good choice for this? I use gentoo at home, but don't think it is a good match for work environmet. EDIT: Note that we are working on cross platform apps, and deployment platform is almost always linux. There are very few windows apps that I have to use (like MS Project). It is just that everything else is windows centric. I use linux because I feel more productive with it, even if I have to dual boot to edit MS Project files.

  • How do I get my laptop's screen brightness settings back?

    - by Mason Wheeler
    From when I bought it up until yesterday, my laptop would dim the screen automatically if you let it sit for long enough, and then if you hit a key or moved the mouse, the brightness would jump back to what you had it at. I enjoy that behavior. It works well. Then I booted it up today, and found that now it will dim the screen automatically if you let it sit for long enough, but it doesn't restore the screen brightness. I have to do that manually, every single time, and it's getting really old really fast. It's an Alienware M17 running Windows 7 64-bit, in case that helps.

  • Can I put a laptop Core i7 CPU in a desktop?

    - by Weezy
    One of the most important thing to me for a CPU is a good mix between speed and heat. For example five years ago I bought a Core 2 Duo 6300 (max TDP 65W): I put a big heatsink on the CPU, no fans (I do hate moving parts and noise) and it worked like a charm and very silently for five years (and it still work but five years later I wouldn't mind a faster CPU and a faster memory controller and more memory). I consider a max TDP of 130W unacceptable (like some high-end Core i7 have), for several reasons. So I was wondering: can I build a desktop and put a Core i7 CPU meant to be used in laptop in it? For example I was thinking about the Core i7 740QM (max TDP 45W [!]). Are these compatible with desktop Core i7 motherboards? (for example on NewEgg it says that the "CPU socket type" for the Core i7 740QM is PGA988, I've not too sure about what this is)

  • Matte or non-widescreen laptop? Do they exist?

    - by Alan Harris-Reid
    Does anyone know of any matte-screen laptops being sold now (15.6 or 17") in the UK? All I can find is the Dell Vostro 3500/3700 range, but there is a premium of around £200 over the price of their Inspiron range (for the 17" model), and I find it hard justifying the extra cost just to have a matte screen. I do not like glossy screens, but it seems the laptop industry has gone the way of "glossy is better - let's get rid of matte". I have read and heard from other developers that as long as there are no strong light sources to reflect off the screen, one can soon get used to a glossy screen, but I am yet to be convinced. I would also be interested if anyone knows of any non 16:9 screen laptops. I find this ratio too wide and not high-enough for the work I do. 16:10 or lower would be better. Any opinions would be appreciated. Alan

  • How can I quickly change display settings from dual monitor to single monitor on laptop?

    - by Daren Thomas
    I have my laptop (running Windows XP SP3) at work hooked up to an external monitor. Whenever I unplug the external monitor (time to go home!) I have to manually change the display settings. This takes time and involves a lot of clicks. Is there a way to automate changing these settings? I'm thinking of a hotkey solution or a little application that I can start with Launchy to toggle between two profiles. I use the MultiMon tool for "extending" the taskbar to the second monitor - will I have to give that up?

  • How do I Connect a 30yr-old Tandy 1400LT laptop to the internet?

    - by Clemens Bergmann
    Just for the fun of it, I want to get an old Tandy 1400LT laptop: small monochrome display two floppy drives rs-232c connector "printer" connector connect the thing the internet and use it as an ssh terminal. How would I connect it to the internet? The software should be no problem as it is a 386 hardware. There should be a small linux distribution which can be run on it. But how would I phisically connect the hardware? It has no ethernet port. Has someone experience with Serial/Paralel-to-ethernet converters?

  • What's the best external hard drive configuration for a software developer laptop?

    - by Dan
    I've got a Dell laptop that I use as a software developer box at work and find that the drive is usually the bottleneck. I'd like to hook up two 10k RPM drives that are striped for performance. I've looked for drive cases with RAID but there don't seem to be very many choices and I'm worried about compatibility with the drives (preferably SATA 2). Also I don't have a SATA connection on my machine so it'll have to USB 2.0 for now. Am I headed down the right path or am I missing a much simpler configuration?

  • The laptop screen goes black after 6 seconds. What can I do?

    - by Riduidel
    I was given a Dell Latitude D-610 today that have a strange display problem : when the computer boot, screen goes black after 6 seconds (delay after which I can still see images, provided light is at the right angle). When such a thing happen, I can get an image again by simply closing the laptop and opening it again. So. What can I do to have the screen working again? opening it and finding in the cable mess which one is responsible for the neon to turn off? considering it lost and cannibalize its parts?

  • Can I use the voice & SMS features of my GSM SIM through my laptop?

    - by i..
    My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

  • 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)

  • My laptop was stolen. What do I need to do?

    - by chris
    My laptop was recently stolen. It was a corporate system running XP, which means it was part of a domain - I'm assuming that makes it impossible for someone to log into it, although I know there are ways to reset the local admin account. Is there any way to tell if someone boots it up? I was logged into gmail, using two factor authentication. I will change my password, but is there any chance of tracking any attempted accesses? Other than changing passwords on all my web accounts, is there anything else I need to do?

  • Which kind of memory do I need for this laptop?

    - by Joshua
    I'm trying to upgrade the RAM in my laptop. It has two slots, but only 1 is filled with a 4gb stick, so I am looking for another 4gb to stick in the other slot. It is a HP g6-1d38dx. I found this RAM, 9-9-9-24, but it is 1333mhz. Looks like it says my max bandwith on the stock stick is 800MhZ. Would that still be cool to use since it is more than the max? http://www.newegg.com/Product/Product.aspx?Item=N82E16820576005 Also will mixing and matching brands have much of an effect? Can someone link a proper module for my machine?

  • Laptop won't load an OS or even an OS setup.

    - by Talasan Nicholson
    My fiancé's laptop started to crash and would get BSOD errors to the point that she couldn't even boot up because it would either take forever or just crash. So I figured I'd try to reformat, as it's done this before and this was the solution last time. On Windows 7, it will not go passed the "Setup is starting..." screen. On Windows XP, it crashes once the setup is about to start (BSOD). I shut it down and let it sit for 5+ hours, in case it was overheating, but it's doing the same thing anyway. By now, I figure it's something to do with the hardware but I hope not. Any ideas?
