  • How to calibrate your mouse's X/Y in Windows Vista

    - by GateKiller
    I've just installed a new Microsoft Wireless Laser Mouse 5000 and it's X/Y calibration/alignment seems to be off. If I move the mouse from left to right, the cursor will go up and down slightly. If I move the mouse from top to bottom, the cursor will also move from left to right slightly too. I seem to remember in earlier version of Windows or Intelli Point, there was a calibration tool which would fix this issue. Can anyone help? Many Thanks Stephen

  • graphics performance better on battery?

    - by Scott Beeson
    Anyone have any idea why my laptop would perform (considerably) better while on battery than while plugged in? It's a Dell Latitude E6420 with Windows 8 Pro. I tried mirroring all the settings in the selected power plan from "On battery" to "Plugged In" and that didn't help. I then just restored the defaults for all power plans (balanced and high performance). I'm still seeing the same results. The best example where it is most noticeable (don't laugh) is Sim City Social in Chrome. I'm probably seeing a performance increase of 5x on battery versus plugged in. This is easily reproducible too. I'm very confused. Could it be caused by dust? The laptop isn't that old and there is no visible dust. I'm not going to take it apart to check the insides as it's a corporate laptop. Could it be overheating? Battery Sim City Social: 68 degrees max Civ V: 77 degrees max Charger Sim City Social: 68 Civ V: did not test See answer below... I'm retarded

  • Which powerful laptop, with UK keyboard and 8gb ram

    - by RobinL
    I've been searching high and low for high spec laptops compatible with Ubuntu. The lack of coherent information on the topic is high (considering the number of people who apparently want a good laptop with an OS operating system). So I thought you may have some advice. My requirements: a) has = 8Gb ram b) is compatible with Ubuntu c) has a UK keyboard and charger d) does not cost the Earth Which would you go for? Does anyone have good experience with high-end laptops running Ubuntu? So here's some background research: Samsung Series 7 looks great, but has various problems on Ubuntu, including: poor battery life, touchpad does not work, graphics card not fully supported and sucks power when it does (see [here] and [here], for example). Other options on the [wish list] include: the sensible [Acer] (possibly n.1 choice, but not sure about graphics card compatibility or battery), a nice looking [HP Pavilion dv6-6c56ea], which also has incompatibility issues (see [here] and [here] and check ubuntuforums) And another [Acer] which may be best due to its simplicity and cheapness. Other sub-questions: didn't Dell offer Ubuntu support for decent laptops (above 6Gb ram their offerings are scarce); what about pre-installed options such as those provided by System76? If it weren't for the UK keyboard and charger, I'd probably go for this [amazing-looking] [machine]. Many thanks for any advice, P.s. Apologies for lack of hyperlinks; I'm a noob so only allowed 2 :( All 10 links are available here though for the interested reader :) Robin

  • How to clear the REPLACEBATT state from APC UPS after hot-swapping the battery

    - by Hubert Kario
    I replaced a battery in APC SmartUPS by hot-swapping. While the swap was all right and didn't disturb connected computers, the "Battery failed" LED on the front face kept glowing. I tried to use apctest from apcups package. Turned off the daemon and run self test (first changing BATTDATE in EEPROM). The test run fine but didn't clear the REPLACEBATT status or the glowing LED. How to clear the failed battery state without powering the UPS and connected equipment down?

  • I'm getting reports that my app is draining the battery, but only on HTC Incredible.

    - by BenTobin
    Has anyone else noticed behavior specific to the HTC Incredible that might result in an app keeping the device awake and busy? I've received reports that my app is responsible for keeping the device awake and draining the battery, but only from HTC Incredible users. My app responds to a number of Intents that might be related. It has a service that starts on boot, and it also responds to changes in network connectivity. I do use a WakeLock, but I'm careful to release it when I'm done processing, and the WakeLock times out after a couple minutes whether I'm done or not. I've heard that the Incredible may have some connectivity problems, or that some of them do. Could it be that the network is going up and down frequently, triggering my app? Any other ideas? I've asked a user to send me their logs with aLogCat. If they're willing, that may help narrow down the cause.

  • Wireless Keyboard/Mouse: Should batteries be removed when not in use?

    - by abel
    I recently bought a Logitech Wireless Keyboard and mouse. I use it almost daily but for a couple of hours only. The keyboard has 2 AAA batteries and the mouse has 1 AA battery. The box mentions that the keyboard has a 24 month battery life and the mouse has a 5 month battery life. Should I keep the batteries in the keyboard/mouse, when they are not in use?Is it safe? Does the battery life mean 24 months of continuous usage or 24 months of average usage?

  • Issue with Toshiba Satellite C50 A-1JM

    - by Nathan Hawkes
    I am having some odd problems with my Toshiba laptop. For the last two days, it has not loaded past the boot screen for hours, if at all. When I force the laptop off and switch it back on, it goes to the Preparing Automatic Repair process but will not complete the process and go to the desktop. However, this only happens when the battery is plugged in. When I remove the battery and run the laptop on power, it works without issue. Would this be a battery issue (given it works without the battery) or a hard drive issue (given it won't get past the boot screen)? If neither, what would you suggest as a solution?

  • Anyone have any experience with bargain laptop batteries?

    - by chris
    I've got an oldish D820 that's got a 100% dead battery. I know that I could, in theory, take it apart and replace bad cells in the battery. I'm not really comfortable with doing that. I also know that there are various places that sell replacement batteries for 20% to 80% of the cost that Dell would charge. Does anyone have any experiences with buying more than a couple of these off-brand batteries? If a battery goes boom, it could be really ugly, so I'd rather not risk it, but at the same time, the dell batteries are really expensive... Any opinions on these ebay / off-brand battery vendors? Thanks!

  • How do I fix the problems I'm having with Xfce and Xubuntu?

    - by Noel Quiles
    I booted into a Xubuntu session and when the splash disappeared it left behind artifacts on the desktop. I went into Desktop to change the background but it stayed completely gray. Not only that, GTK isn't theming any of my windows, nor can I change GTK themes in the settings manager. I recently installed GTK+ 2.x alongside GTK+ 3 for a compatibility issue with xfce-battery-plugin, which also refuses to show anything but 0%. What is going on?

  • ACPI 30k+ interrupts per second

    - by ultimatebuster
    My computer is currently doing something like 30k+ interrupts per second. This causes battery issues as well as the CPU being always stuck at the highest speed, making it very hot (overheating.. 75C at IDLE) Powertop info: 99.4% (32052.4) [acpi] <interrupt> 0.3% (115.9) [iwlagn] <interrupt> Just to clarify this started suddenly a couple of days ago. It didn't have this issue before (though I had a tonne of headaches with Linux on my computer in general..)

  • Multitasking on iOS4 and its stated battery efficiency

    - by eml
    Apple stated that the reason multitasking didn't arrive before iOS4 is because they hadn't figured out how to do it right. Jobs stated at Apple WWDC 2010 that they now do and that they solved the problem of preserving battery performance regarding multitasking. Is iOS4's multitasking "feature" indeed more efficient regarding battery performance compared to Android? Have the Android developers managed to "do it right" too?

  • cpu fan keeps getting faster after removing battery

    - by super_sonic
    Hi all, I have recently pulled the battery out of the motherboard on an old Acer desktop to reset the bios, but when I put the battery back in after about 3-4 hours, and start it up, the cpu fan just keeps getting faster and faster, like it won't stop at all. Does anyone know of a way to fix this problem? Cheers!

  • Broadcom bcm4311 rev2 Full disabled on battery

    - by Antonio BG
    Ok this is my problem... My problem begins while ago when I installed ubuntu 10.10. (is the same with 11.04,11.10...) My wireless card is disabled if the power cord is unplugged, and the only way to fix this is rebooting my pc WITH the power cord plugged and if I use lspci command, it doesn't show me the wireless card. is like if I've removed the wireless board from my laptop port. I've searched a lot of solutions for bcmw4311 issues, but none of them fix my problem because when apply one of the fixes, if I unplug the cord, my wireless card it just gone away... I have dual boot on my pc(w7,ubuntu), I've tried with full installation just to see if this is the problem, but not, is the same. On windows all work correctly with and without power cord.. so this is not a hardware problem, is more like a kernel problem. anyway I can use wireless with power cord plugged, but c'mon this is a laptop not a desktop pc XD haha any help is welcome

  • Dell Latitude D510 Runs From Battery But Not AC Adapter

    - by Jason George
    I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem
