• Connecting my iPhone to iTunes causes my Acer laptop to crash

  - by Paul Sheldrake

  Hello I have an Acer Travelmate 8200 laptop and whenever I connect my Iphone to it, it crashes with the BSOD(Blue Screen Of Death). I have figured out that if I delete all the pictures in my phone I can get it to connect but that is not a ideal long term solution. I also read that it may be a conflict with the built in web-cam I have but I've upgraded the driver and I still get the crashing problem. Any suggestions would be appreciated! Thanks Paul! edit: Here is the BSOD message I get

• Better Performance with Laptop i5+SSD or i7+HDD [closed]

  - by Cas Sakal

  Possible Duplicates: i5 vs. i7 processor dev laptop Developer Notebook i5 or i7 I could not decide on which configuration below gives better performance for developers on a notebook(running VS.NET, SQL Server, no gaming); (A) i5 540M + SSD (Intel) or (B) i7 720M + 7200 RPM HDD (Western Digital) Since these two configurations(A, B) costs nearly same $ for me, I would like to buy the fastest one for my job environment. Please do not comment just buy this or that, if you can give an inference about your choice I would be appreciated. Thank you, cas

• Password Expired Server 2008 R2

  - by Shaharyar

  Hello everybody, We're facing some trouble with our Server 2008 R2 installation. The passwords expired and we're prompted to change the password. After changing it, we get following error message: Configuration Information could no be read from the domain controller, either because the machine is unavailable, or access has been denied. But we aren't even using a domain controller. So we tried running the server in Safe Mode where we get following message after changing the password: An attempt was made to logon, but the network logon service was not started. Are there any other things I could try? All help is more than appreciated!

• Can I build a laptop from scratch?

  - by Ciaran

  I've been looking at this as the same approach as building a desktop computer from scratch but I've never really come across the core things. Can I buy a laptop "case"? Can I buy a motherboard/PSU to fit that case? Can I choose a CPU fan? What are my battery options? Obviously taking into consideration the case. Why isn't this as easy as putting together a desktop computer? Shouldn't there be standards such as ATX? If they exist, what are they?

• Laptop Backup Software (Corporate)?

  - by Hutch

  I wondered if any of you who have a fleet of laptops are using anything to back them up, and if so what? In particular I'm looking for a solution that is totally hands-off once installed i.e. the user doesn't have to do anything, press anything, remember to change something when their domain password changes etc. Right now we use Druva Insync which I have to say is pretty damned good, however our license is up for renewal in a couple of months so I want to be sure it's the best solution before renewing - the only other vaguely comparable product that I know of is from Atempo but the cost of a SQL Server license is a big problem there. Thanks.

• Old laptop turns off due to overheating

  - by Jake Thomas

  I have an old Laptop that powers off when the processor's temperature exceeds 84degs Celsius. The more annoying part is flash causes this the most of the times. If I watch a web feed for more than 15-20mins, it results into hard shutdown of the machine. I have an idea of a could-be solution to this problem, I want a program that would decrease the processor's clock speed to about 1.2GHz or whatever, leading it a lower temperature. Is there a program out there that does this? P.S. Someone please edit this and add the relevant tags, as I'm new and i have no idea of what tags to choose from.

• AC/battery laptop issues(not a simple charging fix)

  - by Deric Hatchett

  Is it possible to run a laptop off the battery while the AC is plugged in? I can play games no problem while just the battery is plugged in, but obviously that means I have to let it charge after every hour or so. But, when I plug it in to charge, it can't handle any video games anymore. I thought it was the brick in the power cord going out, but I just bought a new one and it still doesn't work. The specs are actually better than the old cord. I think the problem is an over heating problem in the AC outlet, but if it charges the battery while I play, it would work just fine running solely off the battery.

• Cheap, light, small Skype laptop?

  - by roufamatic

  My wife and son are heading out while I stay home to babysit some contractors. We discussed getting her a small, cheap laptop that would primarily be used for Skype. Good quality integrated video & mike are prerequisites, as is Windows (though I'd entertain OSX). Doesn't need to be large, a 12" screen is probably fine. If I went new, where should I look? And if I were going to test the used/craigslist waters, what specs are we talking about?

• How to run a file with sudo without a password?

  - by John

  I've made a script that preforms various system tasks, that I run regularly, but I have to use sudo to run the script, despite the fact that I own it because it runs root privileged commands. How can I add make sudo let me run this one file without having to enter my password every time I run it? I know that there are questions regarding running commands without a password, but I wasn't able to find one on running a file without a password. I am aware of the security risks, but I'm at home on a computer that I trust.

• Which Windows OS Supports 8 GB RAM in a Laptop and Suggestions for a Better Laptop for Personal & De

  - by Ellen

  I am about to purchase a laptop and have zeroed on the following two of them. Toshiba L500-ST2544 Toshiba L505-ES5034 The Common Specification for both of them are as follows - RAM - 4GB DDR3 Memory HDD - 320 GB Processor - Intel® Core™ i3-330M Processor WebCam and Mic - Available HDMI Port - Available Numeric Key Pad - Available Windows 7 (64 bit) Home Premium Now, the only difference between ST2544 and ES5034 is that, the ST2544 has a maximum of 2 slots with 2 GB in each. So, you can have a max of 4 GB RAM in that. The ES5034 can support 8 GB RAM, so, in a couple of years, if I want to add another 4 GB RAM I will be able to do it. The price for ST2544 is USD 629.00 whereas, the price for a ES5034 is USD685. A difference is USD 55.00 (not a major amount, but still something extra). Is it worthwhile going for the ES5034? Which Windows Operating System supports 8 GB of RAM?

• laptop suddenly became very slow

  - by Ieyasu Sawada

  I have a compaq laptop. And I've been using it 2 years now. Then this day, it suddenly became very slow. It almost took 5 minutes from turning on to the log on screen. I click my username and it took 3 minutes to show the desktop. I click on my computer then properties to see if it is still showing 2 Ghz for the Core 2 duo processor. And 2gb for the memory. It took 10 minutes for all the information to show up. And its still 2gb and 2Ghz. So I may conclude that this is not a problem in memory or cpu. Its still running perfectly last night. And I have not seen signs of it failing. Things I already tried: Rebooting Shutdown then turn on again So how do I determine what causes this problem? How do I fix it?

• How to change password schema for Dovecot user authentication for an already existing mail server

  - by deb_lrnr

  Hello, I have an email server setup on Debian Lenny with Postfix, Dovecot, SASL and MySQL. Currently, the password scheme in my dovecot-sql.conf file is set to: CRYPT default_pass_scheme = CRYPT I would like to globally change the scheme to something stronger like SSHA, or MD5-CRYPT and re-hash all passwords with SSHA. What is the best way to do this? The Dovecot wiki mentions how passwords that don't follow the default scheme defined in dovecot-sql.conf can be prefixed with "{ssha}password", but I couldn't see anything regarding changing an already-existing scheme to a new one for all passwords that are already in the database. Thanks for your help!

• tools to check password security

  - by tombull89

  Hello again. I'm after a tool to test how long a password could stand up to a hacking/cracking technique such as brute force as two passwords that are critical to a work system is one word that is in the dictionary, and another is a word in the dictionary with a capital letter and a number instead of a letter. I'd prefer it to be offline and free that you can run on a computer to see how long the password will hold out. Maybe even at the windows login prompt but I realise such programmes may be shady and erring on the side of illegal. Anybody have any suggestions?

• How do laptop battery voltages affect runtime?

  - by Bigbio2002

  I ordered a new battery for my faithful XPS M1710. I'm not sure of the voltage of the battery I have now, but the new one that the Dell rep got me (after 3-4 times confirming my phone number and laptop model number) is 14.8v. I was a bit concerned about potential incompatibilities (as most of the other compatible batteries listed were 11.1v), but I figure that there's no way that Dell would "recommend" batteries that wouldn't work or fry your system. Now, my question is, how does voltage affect battery life? If we assume the needed power draw to be constant, a higher voltage would indicate less amperage needed, therefore the battery would last longer before running out, yes? Or am I missing something? For reference: P=I*V P = power I = current V = voltage (duh)

• using git on DOS command line asks for password - but not when using TortoiseGit or gitBash

  - by Sandy

  I would like to use the DOS command line to enter the command: git clone "git_path.git" myDir It asks me to enter a password which I would like to avoid. I usually use TortoiseGit to do all git related operations. I would like to setup cruisecontrol using ant with a custom git task. Therefore I need to perform git clone on the command line in Windows 7. But it only works using git bash and not DOS. According to other forum entries, I tried to convert the key with puttyGen and put the file id_rsa in c:/Users/myName/.ssh I also added an authorized_keys file but it still asks for a password. Any ideas? Thanks

• How do I set the root password so I can use su instead of sudo?

  - by Zignd

  Warning: Directly logging in as root is like playing with fire, because one little typo is enough to lose critical data or make your system unbootable. Note that desktop environments will also function incorrectly if you login to them as root. See these questions for the reasons behind why sudo is preferred and why root-login is disabled by default: What are the benefits of sudo over su? Why is there no option to login as root? Instead of letting you set a password for root during install Ubuntu set it to * for no password and disables the actual account login, however even with this being said you can still use root in ubuntu by sudo. So how to set a root password on Ubuntu?

• HP laptop won't recognize wireless adapter

  - by Dennis Williamson

  I have an HP Pavilion dv6400 series laptop with an NVidea chipset which is the subject of a class action lawsuit. The symptom (PDF) that I'm experiencing is that the system fails to recognize that there is a wireless adapter installed. It doesn't appear in Device Manager. Is there some way, short of installing a new adapter, that I can work around this problem? The system is running Windows Vista Home and has the latest BIOS (F42) and Windows updates and drivers. See this related question where I ask how to use an old Windows Mobile phone as a Wi-Fi (not cellular data) tether.

• Laptop hot after format [migrated]

  - by Dany Khalife

  I recently formatted an HP G62 Laptop and installed all drivers from the HP site that should be installed for this model. But i noticed a very strange behavior, using Coretemp, the temp is always above 50 (on idle) and reaches 70 very quickly sometimes (Critical is 90) If i open youtube or skype alone, i can get temperatures as high as 83. Normally it was around 32 (on idle) and reaches 70 when i open games but not youtube.... I have a i3 processor and AMD graphics so i am wondering if somehow it's a graphics card issue (since i3 has integrated graphics as far as i know) Device manager shows only AMD graphics card tho, not sure if i3 graphics should appear here too. Any ideas what i might have forgotten to do after the format ?

• How to choose between Mac Laptop and Desktop

  - by Sakamoto Kazuma

  I am looking at getting a Mac soon for both iPhone development, and video editing. Should I be looking at a desktop or MacBook? I do not plan for the machine to move from my desk at home, so portability is not an issue, however it will be next to both a windows 7 desktop as well as a Linux laptop with dock. Main things that I'm concerned about is whether or not a MacBook has the power needed to do the video editing that I'm planning on doing and whether or not I can afford a desktop.

• I modified my registry and now my laptop doesn't report its battery or power settings

  - by Crouch

  I saved a backup of my registry and then made a change to it. After the change, the Windows 7 battery meter no longer reported how much battery power was left. I also was no longer able to change between Power Profiles in the Control Panel. I tried to restore the original registry but it didn't restore the lost power features. Now I have to keep my laptop plugged in all day because I never know how much power I have left. Anyone know what to do here?
