5. Operational Procedures

5.1 Given a scenario use appropriate safety procedures

If an older program doesn't run correctly, use the Program Compatibility Wizard to simulate the behavior of earlier versions of Windows.

Installing peripheral devices such as printers at customer premises: Expect that your customers are not very familiar with the usage of the the device. Show the customer how to use the device. For example, if you had installed a printer, show the customer how to use the printer and also print a test page. Relevant manuals (hard copy or electronic version) along with drivers need to be provided to the customer.

Hot-Swapping: Usually, you need to consult the manufacturer's documentation to verify which components are hot-swappable. Therefore, it is recommended to refer the documentation, and if the power supply is hot-swappable, there is no need to switch off the server computer, thus preventing any inconvenience to the users.

Slow system response or start up problems: Possible reasons for slow running of a computer may include insufficient memory, viruses and Trojan horses, too many TSRs (Terminate and Stay Resident) running at the same time, etc. Ensure that your computer has sufficient memory, hard disk space, and anti-virus software installed (particularly if connected to the Internet).

Windows Logo'd Products List provides compatibility information with existing software, and MS recommends that you check the same.

Placing the paging file on different physical disks is optimal. This will improve faster access to the Paging file, and also distribute the load.

By default, Windows 7 stores a user's profile in the C:\Users\ folder on the computer the user logs on. When a new user logs on, his initial user profile is an exact copy of either the local or domain-wide "default user" profile folder. The local default user profile folder is located in %root%\Users. If you have installed Windows 7 in C drive, it is C:\Users\ <user_name>.

The proper options for throwing away the old equipment

  • Donate to a charity
  • Recycle it by giving it to a recycle center
  • Give it to a training school in the neighborhood

Batteries contain environmentally hazardous chemicals and therefore, should not be disposed through dustbin. Always refer to the manufacturer's instructions or the relevant State guidelines. The same is true when you are disposing chemical solvents.

Electrostatic discharge (ESD) can damage the component at as little as 110 volts. CMOS chips are the most susceptible to ESD. Static electricity builds up more in cold and dry places. Use humidifiers to keep room humidity at about 50% to help prevent static build up.

MSDS stands for Material Safety Data Sheet. It is US state department document that contain information on any substance that is hazardous, and proper use / disposal.

When working on computers, use special ESD wrist strap. Do not directly ground yourself with a piece of wire. An ESD wrist strap has built-in resistor to prevent electric shock. Use specially designed grounded ESD mats. Do not wear synthetic clothing. Place all electronic components into anti static bags. Anti static bags can be reused. Keep your workplace clean.

Follow anti-static precautions before touching any electronic components inside a PC.

As the humidity decreases, static build up will increase and vice versa. A level of 50% is considered safe. Below 50% humidity, static build up will be more.

To clean a keyboard soak it in a distilled demineralized water as soon as possible after the spill. Take precaution to remove the keyboard before doing so, and dry it before connecting back.

The MSDS contains wealth of information including Product and Company information, First aid measures, Handling and storage, Physical and chemical properties, etc.

Laptop batteries (and most other batteries) consist of hazardous material. You need to dispose them according to the hazardous material disposal procedures. Enquire local authorities about disposal procedure.

Sensitive discussions overheard are confidential, and should be treated accordingly.

While repairing failed boot problem some folder containing usewr data were lost during the repair process , in such a case you need to take the customer in to confidence, and apologize to him/her for having lost some important files/folders.
