For many years Hewlett Packard has been a recognized leader in the world of computers, printers and associated technologies. The printers the company makes are widely used in both homes and businesses, and many older HP printers are still going strong. That means that the owners of these printers will need to have some basic troubleshooting skills so that they can resolve common problems when they occur. Calling for service on a printer like the HP 1600 can be very costly, so doing the work yourself can save you a lot of money.
Instructions
Determine the source of the problem by sending a print job or test print to the HP 1600. If the printer is grabbing multiple sheets of paper instead of just one, the problem could be as simple as moisture in the paper. Many HP printers, including the HP 1600, are quite sensitive to the moisture content of paper, and moisture can cause the printer to grab two or more sheets instead of one. This results in frequent paper jams, and sometimes in torn paper being left in the printer.
Turn off the HP Laserjet 1600 and remove the power cord from the back of the unit. Open the front cover of the printer and carefully pull the toner cartridge out. Watch for any loose toner as you pull the cartridge out of the printer.
Turn the toner cartridge over and examine it for any signs of leaking toner. If there is a leak you will generally see an accumulation of black dust at the bottom of the toner cartridge. If the toner cartridge is leaking it should be replaced right away--leaking toner can damage the printer.
Use a small vacuum cleaner to remove any paper dust and toner from the inside of the printer. The interior of the HP 1600 is very open and accessible, making it easy to work inside with a vacuum. A small handheld vac designed for use on computers is the perfect tool for this job.
Pull the paper tray out of the printer and make sure that all of the paper guides are set correctly. Also make sure that none of the tabs on the paper tray are broken off. The tabs used on this model are thin and somewhat easy to break, and if they are damaged the paper will not feed straight. This can result in paper jams and other issues. If the tray is damaged, a replacement can be ordered from HP or one of its authorized sellers.

Problem:
I got a laptop here but the password is expired, there are no other user names on which i can break into.
I tried using Microsoft's on password recovery disk but that failed.
Any ideas?
Solution:
Windows 7 Expired Password
You can change your password to something you will remember from another administrative user's account. If you only had one administrative user account and you've forgotten the password, all is not lost. You might then want to follow the general recommendations for setting up user accounts in Windows 7 that I'll give you at the end of this post. After you are back into the system, if this is a home computer and not a domain member you can disable the password expiration requirement as follows:
Start Orb>Search box>cmd
When cmd appears in Results above, right-click and choose "Run as administrator"
Stop the
Password Expiration - at the
command prompt type:
net accounts /maxpwage:unlimited [enter]
You will get a message box “The command completed successfully” and then you can close the command prompt.
Doing all this requires a certain level of computer skills. You know yourself best and whether taking the machine to a competent local computer tech (not a BigComputerStore/GeekSquad type of place) is the better solution for you.
If you have a Windows 7 installation DVD (not a recovery DVD) you can boot the system with it. Select the default language, then choose "Repair your computer". Then select "Command Prompt". At the command prompt type:
net user administrator /active:yes [press Enter]
net user [insert your user account's name here] [insert new user password like 1234 here] [press Enter]
Remove the installation DVD and reboot the computer. Now you will be able to log into your user account using the password you set; i.e., 1234.
If you don't have a Windows 7 installation DVD (only have a recovery disc), the computer mftr. may have given you the Windows 7 System Repair option (not a System Recovery!) on the diagnostic menu. This diagnostic menu is the same one where you can choose Safe Mode. Get to this menu by repeatedly tapping the F8 key as the computer is starting up. If you don't have this option you can make a bootable Windows 7 Repair DVD from the file at this link:
http://neosmart.net/blog/2009/windows-7-…
Note: All the Neosmart recovery disc downloads are torrent files. There is a good explanation of torrent files at the Neosmart website. You will need a torrent client such asmuTorrent to get the files. The torrent client will download the .iso file with which to create the bootable DVD. If you are creating the bootable DVD in an older operating system (XP, Vista), you will need to use third-party burning software such as Nero, Roxio, or the free ImgBurn (
http://www.imgburn.com ) to burn the .iso as an image, not as data. Windows 7 can burn .isos natively.
Once you have fixed things, log into the extra administrative account you will make per the suggestions below and disable the built-in Administrator account again for security purposes:
Start Orb>Search box>type: cmd
When cmd appears in Results above, right-click it and choose "Run as administrator" [OK]. Now you will get the command prompt. At the command prompt type:
net user administrator /active:no [enter]
Exit the command prompt.

Problem:
Processor: Intel Celeron C900
Operating System: Windows 7 Home Premium
I have an advent roma 1000 laptop, I have had it for over a year and occasionally had problems such as this, last time I found a solution on the internet but I have not been able to find it since, it was something to do with going into control panel and power settings, but I can't remember. Every time I press the shutdown button in the start menu, nothing happens, every time I press the power button on the laptop itself nothing happens. I have changed power settings so that my laptop shuts down when I close it but when I close it and open it again nothing has changed. Please help!
Solution:
Windows 7 laptop wont shut down issue could either be Software or Hardware related. Boot into Safe Mode and check if you can shut down properly.
Boot your computer in Safe mode.
If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
Perform a hardware clean boot to determine if any hardware is posing this problem.
1. Go to start and type device manager.
2. Select device manager from the Control Panel list.
3. Right Click on Sound Card, Video Adapter, and Network Adapter one by one and click disable.
4. Reboot the computer. If the problem is fixed then you can enable the hardware devices one by one to find the exact device that caused the problem.
After you found the device that is causing the problem, installing the device’s latest driver should fix it unless it’s a hardware issue.

An HP Officejet printer is a copier, printer and fax machine all in one. These printers offer different styles and features, depending on the model or "series" you purchase. Officejet printer problems are inevitable, especially if you have used the printer for a long time. You should be able to troubleshoot printer issues so that they do not interfere with your printing jobs.
Instructions
Check for jammed papers inside the printer. Signs of paper-jam problems include strange noise inside the printer, "jammed paper" error messages or the printer ejecting blank documents when you are trying to print a document.
Turn off the printer, and unplug the power cord from the outlet. Remove the rear access door in back of the printer. Reach for and remove any jammed paper inside the product slowly and very carefully. Dot not pull a jammed paper from the front of the unit where paper is ejected. Once you clear any jams, replace the access door and try to print another document. If the printer still does not print, another factor may be causing the problem.
Make sure that the USB/parallel cable and power cable are properly attached to their respective printer ports. Turn off the printer, and power it back on.
Visit the manufacturer's website and check for recent updates for your printer driver. If there are updates available, download and install them to your computer.
Remove an empty cartridge immediately from your computer. Open the front cover of the printer, wait for the carriage to move to the center, and remove the empty ink cartridge. Replace it with a new, genuine ink cartridge. Refer to the user manual of your printer for specific instructions on how to install a new cartridge.

Problem:
For some unknown reason, my internet is running really slow. If i reset my router and modem, then my internet will run smoothly for 5-10 minutes, but then goes back to running really slow. So i have to reset my router again, and so on. Which gets a little irritating. So i'm wandering how i can get the internet up to normal speed permanently. I've already removed loads of programs that were taking up unnecessary space, but it has made no difference. What should i do? PLEASE HELP
Solution:
Follow the given instructions if your
internet is slow:
1. Find the browser that works for you
Most people still use Internet Explorer, even though it's not the fastest browser out there. If you are an active Internet user, it would be a good idea to check out different browsers, like Chrome, Firefox, and Opera to see which one works best for your connection type and your hardware configuration. For example, Chrome is particularly good for computers that are low on RAM, as it's not as memory hungry as Firefox and IE.
2. Tweak your router
If you are using a router, you can probably speed up Internet by adjusting the router settings. There are too many routers to give specific advice, but most routers can be tweaked to open up ports and boost your Internet speed. Just check the manual for things that can be done to improve performance or use Google to find answers for your particular router.
Before you do any tweaking, check whether you are close enough to the router when you use the Internet. Being too far away from it can make the connection really slow and unstable.
Another thing you should try before changing any settings is to restart your router. Sometimes this simple action can dramatically speed up your Internet connection.
4. Prevent unauthorized access
If you are using wireless Internet connection, make sure that you are not sharing it with the whole neighbourhood. The more people use your connection, the slower it is for you. So at the very least set up a WEP password to stop unauthorised users from using your Internet connection. Or if your hardware is compatible, set up WPA encryption.
5. Control your bandwidth usage
There are many applications that will use your bandwidth in the background, like Windows Update, Windows Live Messenger, Skype, Real player, Adobe Reader updates, and other similar software. Most of them usually start automatically when you log on to Windows and connect to the Internet as soon as there is a connection. This means that these programs use your bandwidth when you are not actually using them.
Most of these applications can be configured not to start on Windows log-on or to at least ask permission to connect to the Internet. If you are not sure which programs are secretly using your bandwidth, you can use a free tool called Auslogics Task Manager. With the help of this program you can track which applications and processes are consuming your network traffic.
If your Internet connection speed dropped all of a sudden for no apparent reason, check your computer for malware and spyware. Malicious software often uses your Internet connection to send information to its developers.
6. Perform some basic PC maintenance
If your computer is slow, it doesn't matter how fast your Internet connection is – everything will be slow because you computer can't cope. The answer to that is to keep your computer in good shape and perform regular maintenance like disk cleanup and defrag, registry repair, and other tasks like monitoring your startup items and optimizing Windows services. This way you will not only improve computer performance, but also speed up Internet connection.
