This section provides information for the additional features that are part of your computer.

Memory Module Guidelines
To ensure optimal performance of your computer, observe the following general guidelines when configuring your system memory:






Memory modules of different sizes can be mixed (for example, 2 GB and 4 GB), but all populated channels must have identical configurations.
Memory modules must be installed beginning with the first socket.
NOTE: The memory sockets in your computer may be labelled differently depending on the hardware configuration. For example, A1, A2 or 1,2,3.
If the quad-rank memory modules are mixed with single or dual-rank modules, the quad-rank modules must be installed in the sockets with the white release levers.
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).

Front Panel Chassis Lock
The front panel chassis lock allows you to lock the front panel. The lock is located inside the chassis. It consists of two buttons: •


orange button — press this button to lock the front panel. green button — press this button to unlock the front panel.
NOTE: To lock or unlock the front panel chassis, always ensure that the left cover of the chassis is removed. For information on removing the left cover, see Removing Left Cover.

45

Power Supply Unit (PSU) Lock
The PSU lock prevents the removal of the PSU from the chassis.
NOTE: To lock or unlock the PSU, always ensure that the cover of the chassis is removed. For information on removing the left cover, see Removing the left cover.
To secure the PSU, remove the screw from the unlock screw location and tighten the screw to the lock location.
Similarly, to unlock the PSU, remove the screw from the lock screw location and tighten the screw to the unlock screw location. 46

Diagnostics

5

If you experience a problem with your computer, run the ePSA diagnostics before contacting Dell for technical assistance. The purpose of running diagnostics is to test your computer's hardware without requiring additional equipment or risking data loss. If you are unable to fix the problem yourself, service and support personnel can use the diagnostics results to help you solve the problem.

Enhanced Pre-Boot System Assessment (ePSA) Diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device groups allowing you to:


Run tests automatically or in an interactive mode



Repeat tests



Display or save test results



Run thorough tests to introduce additional test options to provide extra information about the failed device(s)



View status messages that inform you if tests are completed successfully



View error messages that inform you of problems encountered during testing
CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid results or error messages.
NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal when the diagnostic tests are performed.

Troubleshooting Your Computer

You can troubleshoot your computer using indicators like Diagnostic Lights, Beep Codes, and Error Messages during the operation of the computer.

Diagnostic LEDs
NOTE: The diagnostic LEDs only serve as an indicator of the progress through the Power-On Self Test (POST) process. These LEDs do not indicate the problem that caused the POST routine to stop.
The diagnostic LEDs are located on the front of the chassis next to the power button. These diagnostic LEDs are only active and visible during the POST process. Once the operating system starts to load, they turn off and are no longer visible. Each LED has two possible states of OFF or ON. The most significant bit is labeled with the number 1, and the other three are labeled 2, 3, and 4, as you go down or across the LED stack. The normal operating condition after POST is for all four
LEDs to be ON and then turn off as the BIOS hands control over to the operating system.
NOTE: The diagnostic lights will blink when the power button is amber or off, and will not blink when it is white.

McDonald’s is already known for their low meal prices, and then McMahon improves on it at her branch by offering a monthly discount. I feel that the overall image of McDonald’s in her local area is improved by her strategy because a lot of the local population is seniors and this particular strategy involves them, so their opinions of the place should be high.

...Review Questions Chapter 1 1. Use the characteristics of a project to differentiate it from a nonproject. Projects have a specific and unique tasks that aim to achieve a deliverable at a specific due date. They have a completion date when since start till termination date; and they require multidisciplinary input from different people with different knowledge and expertise. Nonprojects don’t necessarily have a deliverable and a due date. They can be routine work. 2. Identify the three goals of a project and describe how the project manager achieves them. What does it mean for a project to be “overdetermined”? The three goals of a project are to generate the scope of project, maintain specified budget, and finish on time. The project manager must adapt to unpredictable changes, become flexible, and be ready to trade-off one objective for another. For example, if the project is falling behind schedule, outsourcing or crashing would be a way to catch up with schedule. It might cost more, but it’s a trade-off between predetermined budget and schedule. Overdetermined means that projects have specified deliverables, budget, and schedule with no anticipated flexibility. 3. Contrast the two types of project life cycles and discuss why it is important to know which type the current project is following. The two types of project life cycles are the S and J shape life cycles. The S-Shape life cycle has a slow start and finish with a quick momentum before......

...other. Hence the famous Romantic friendship pairs: Goethe and Schiller, Wordsworth and Coleridge, Hawthorne and Melville. Modernism decoupled this dialectic. Its notion of solitude was harsher, more adversarial, more isolating. As a model of the self and its interactions, Hume's social sympathy gave way to Pater's thick wall of personality and Freud's narcissism — the sense that the soul, self-enclosed and inaccessible to others, can't choose but be alone. With exceptions, like Woolf, the modernists fought shy of friendship. Joyce and Proust disparaged it; D.H. Lawrence was wary of it; the modernist friendship pairs — Conrad and Ford, Eliot and Pound, Hemingway and Fitzgerald — were altogether cooler than their Romantic counterparts. The world was now understood as an assault on the self, and with good reason. The Romantic ideal of solitude developed in part as a reaction to the emergence of the modern city. In modernism, the city is not only more menacing than ever, it has become inescapable, a labyrinth: Eliot's London, Joyce's Dublin. The mob, the human mass, presses in. Hell is other people. The soul is forced back into itself — hence the development of a more austere, more embattled form of self-validation, Trilling's "authenticity," where the essential relationship is only with oneself. (Just as there are few good friendships in modernism, so are there few good marriages.) Solitude becomes, more than ever, the arena of heroic self-discovery, a voyage through......

A care assistant can help to give clients a sense of approval by regularly asking the clients of they wanted to do something, for example walking or gardening, this will help to make the clients feel loved and cared for by others. Also if clients have received a new haircut or new clothes then the care assistant should complement them and praise them for how they look. Lastly a care assistant should find out different things about the clients that they are caring for as a way to get to know them better and be able to talk about their interests more with them. Kitchen staff and the chef can show a positive attitude to clients by smiling at them and saying hello whenever they see them, this will give clients a positive feeling towards the kitchen staff and chef.

...Hello World This is just a sample essay.   Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham. There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to......

...“Do not impose on others what you do not wish for yourself.” – Confucius Applying the Golden Rule - refusing to engage in intentional and avoidable harm - promoting the overall welfare of host country citizens - avoiding violation of host country norms Scenario: Company X in host country allows unsafe practices such as workers climbing high-rise structures without proper harnesses and safety lines or operation of loud machinery without hearing protection (ear plugs). By home country’s safety regulations, these practices are deemed unsafe and clearly violate the golden rule. Switching roles with the workers, you would not want to put your life on the line every time you climb structures to do your job. Or you would not want your hearing to be impaired after years of operating loud machinery without hearing protection. Therefore, there is a clear violation of the Golden Rule. Another scenario will be in the case of exploitation or slave labour. Goodin’s 5 conditions: 1) Imbalance of power between the exploited and the dominant 2) Exploited party needs the resources provided by dominant party to protect his vital interest 3) Dominant party exercises discretionary control over this vital resource 4) Only access to this resource is through the exploitive relationship 5) Resources provided by the exploited are used without adequate compensation By the Golden Rule, it is safe to assume that no one would want to be exploited or be enslaved and be stripped of......

But before Ender headed to school an International fleet officer came to the house to have a talk with Ender. Colonial Graff came to inform that Ender nearly beat a kid too death, but wanted him to also inform them that Ender passed and was eligible to enter battle school. Ender was shocked at what has just happened because of the whole monitor incident. Enders parents were very angry with Colonial Graff for just not wanting Ender to needing him after what he has done. Colonial Graff told them it was part of the last test and that he has passed. He said that Ender didn’t just beat him, but he needed to so he can protect him self from harm. So Ender went with him because he felt that it was what he was born for. Reflection: This made me feel angry with Colonial Graff because not only did he convince Ender, but also he lied to him about what his family thinks of him. I think the outcome would have been different if Ender just stayed with his family and moved on too his abnormal life. If I were to predict what will happen next I would say Ender is going to the battle school were he will learn to become the next commander.
