# Printers, Monitors, and Other Hardware # What some RAID levels? - RAID 0: RAID 0 sacrifices fault tolerance for raw speed. It doesn’t store parity information, but with its small stripes, it can work with large files much faster than any other RAID. Because it is not fault tolerant, RAID 0 is inappropriate for the storage of critical data. - RAID 1: RAID 1, also known as disk mirroring, makes use of neither striping nor parity information. Instead, each RAID 1 array consists of two disks that duplicate each other’s data and are treated as one drive. A computer can read from both disks and thus access data faster. However, because the entire contents of a disk are duplicated, RAID 1 uses space less efficiently than RAID levels that store parity information. - RAID 2: In RAID 2, some drives are striped while others hold error checking and correcting (ECC) data. Because nearly all modern drives have ECC built-in, RAID 2 is infrequently implemented. - RAID 3: In RAID 3, all but one of the drives in the array are striped. The final disk is devoted to the storage of parity information. RAID 3 stripes are small, so all the disks work together when reading and writing large files. This greatly increases performance, but as each task accesses all the disks, it is not possible to overlap I/O (i.e., do two tasks at the same time). For this reason, RAID 3 is inappropriate for multi-user environments. - RAID 4: RAID 4 is identical to RAID 3, except that it uses large stripes instead of small ones. Because files usually only span one drive, it is possible to overlap I/O. Unfortunately, because each access must update parity information, the parity drive becomes a bottleneck that increases in severity as the number of drives increases. - RAID 5: RAID 5 is similar to RAID 4 except that, rather than devoting a single device to parity information, it divides it among all the drives. This eliminates the bottleneck created by RAID 4’s parity drive. - RAID 6: RAID 6 is like RAID 5 except that it adds a second parity scheme. It is slower than RAID 5, but offers greater protection of data. - RAID 7: RAID 7 is a proprietary solution offered by Storage Computer Corporation. It is a very expensive, high-speed option that relies on caching and an embedded operating system that manages I/O. - RAID 10: A RAID 10 (i.e., RAID 1+0) array uses several RAID 1 arrays and stripes them to form a single unit. RAID 10 is very fast and highly fault tolerant, but also extremely expensive. - RAID 53: RAID 53 is similar to RAID 10, but each segment is a RAID 3 array rather than a RAID 1. Like RAID 10, it is fast but expensive. - RAID 0+1: A RAID 0+1 array is essentially a RAID 1 array built from RAID 0 array units. It offers very fast performance and good fault tolerance, but it is very expensive. # When I print my pdf files, only a portion of my document gets printed and is magnified to fill the entire sheet or paper.

If you have a Dell UltraSharp LCD monitor, and would like to check which company made the LCD panel, follow these steps: 1\. Make sure that the monitor is connected and is displaying an active video signal (e.g. the Windows Desktop, the BIOS, etc.) 2\. Power off the monitor. 3\. While holding down the Menu and + buttons on the monitor, power it back on. 4\. After the video signal reappears, release the buttons, and press the Menu button once more. 5\. In the menu that appears, look for a three-letter code on the top left area, to the left of “Dell”. # Dell Laptop Battery Recall If you have a Dell laptop model: - Latitude: D410, D500, D505, D510, D520, D600, D610, D620, D800, D810 - Inspiron: 500M, 510M, 600M, 700M, 710M, 6000, 6400, 8500, 8600, 9100, 9200, 9300, 9400, E1505, E1705 - Precision: M20, M60, M70, M90 - XPS: XPS, XPS Gen2, XPS M170, XPS M1710 purchased between April 2004 and July 2006 please remove the battery and check the serial number.

Unfortunately, if you select a non-native resolution, the text can look fuzzy or jagged. The only way to tell is to try various Display settings and determine which looks best to your eye (even if too small or too large). These are accessible from Control Panel > Display > Setting tab. Then you can adjust the size of the objects on screen by changing the DPI setting. This is accessed via the Advanced button. Typically this needs to be increased — 120% has been a popular setting on our 19" monitors. Unfortunately, this requires admin rights to your PC and a reboot to take effect. Finally, if the text doesn’t look as sharp as you’d like you may wisho to adjust your ClearType settings in Windows. You can not only change this under the Effects button on the Appearance tab but also fine-tune it further at [http://www.microsoft.com/typography/cleartype/tuner/1.htm.](http://www.microsoft.com/typography/cleartype/tuner/1.htm) # How can I find a dead or stuck pixel on my LCD monitor?

Specs often read something like “up to X – X hours.” The “up to” covers a lot of ground. “Up to” is standard advertising lingo. They lie. - Make sure your battery is fresh—that is buy your laptop from a reputable source with high turnover. Lithium Ion batteries lose approximately 20% of their capacity every year – even just sitting on a shelf. - Buy a decent amount of RAM; 2 GBs at least. The less the laptop has to use virtual memory, the less juice is wasted on writing stuff out to disk. **Once You Have Your Laptop** - If you don’t plan to use the battery for a while, charge it to about 40 percent , remove it and put it in a cool dry place. Do not put it in the fridge or you family will question your drug habits. - Don’t completely discharge your battery – it’s not good for lithium ion batteries. - Use **Power Options** in the **Control Panel** to adjust your power management scheme. Select the **Power Savings** setting for best battery performance. - Use the correct power adapter for your laptop. A mismatch in wattage could cause an overload and damage both your laptop and battery. **Physical Devices** - Reduce the number of external devices you use – USB devices (including your mouse) use up energy. - Disable Wifi if you are not using it. Wifi uses energy simply searching for signal. Many laptops have a manual method (a switch, sometimes function keys, normally labeled with an icon that looks like a radioactive tower). - Dim your screen. Brighter screens use more energy. Usually you will find screen dimmer keys on your function keys, the top row of your keyboard. - Single-task. Multi-tasking uses more energy. - Skip the CD/DVD drive. Transfer your movies and stuff to the internal hard drive and run them from there. - Keep the temperature cool and keep your laptop well-ventilated (look for air vents on your laptop and make sure they aren’t blocked – or dirty). - Keep your work area and laptop clean. Dirt and dust in the vents or in the guts of the machine makes your laptop heat up and work harder. - Keep the battery contacts clean. Note the metal contacts on your battery and clean them with rubbing alcohol on a soft cloth. - Hibernate rather than standby. Standby does save power but Hibernate saves more and will also preserve your PC’s state. # LaptopRepair.com [LaptopRepair.com](http://www.laptoprepair.com/ucla) will service most out of warranty PC laptops – also warranty repairs on select brands.

Since most printers accept data much slower than the printing application can process it, “spooling” can make life easier by capturing the data going to your print driver, putting it in a holding area (temp files on your hard drive), and then spooling it in the background later, at a transfer rate that the printer can handle. In a sense, the spooler is the middleman between your printing application and the printer and it sits in the background “feeding” the printer as fast as it can take the data. Windows employs two methods of feeding the printer via the print spooler: raw and EMF (enhanced meta-file). Let’s take a look at both spooling methods. EMF: “Enable Advanced Printing Features” ON If there is a check in “Enable Advanced Printing Features”, you have turned EMF printing on and have told Windows that it can defer some of the print processing until late \[…\] EMF: “Enable Advanced Printing Features” OFF If “Enable Advanced Printing Features” is turned off (unchecked), Windows will create a spool file in the raw format. That is, the driver is invoked up front (as your printing application is processing the data/pages) and the raw data that is ready for the printer to receive is spooled into file(s) \[…\] Simply put, raw printing with “Enable Advanced Printing Features” turned off is more reliable — # Reset drum light on Brother HL-2270dw After replacing the drum on a Brother HL-2270dw printer, the drum replacement light may still be flashing on and off indicating replacement is needed.
