Virtual Desktop

Today we went onto the internet and we viewed a virtual desktop PC. It gave us all the information about the different internal and external components of the computer and it let us put these components into their places again by showing us. we then got the optional way of doing a test on all of the components and when we did this we were not given any help and we had to put the parts back into their places ourselves. i found this quite interesting because not only did it give us the information but we were also tested on our own knowledge of the components. the only downside to this virtual dasktop is the fact that it had alot of information at once and it was slightly difficult to memorise all of this informtaion.

HSE Safety

This document is about advice on how to avoid injury while fixing and repairing appliances within the home such as, fridges, freezers, kettles, toasters, microwaves, etc.

1. The most considerable danger to people carrying out electrical work is that they might get an electric shock. There is also a danger of burn injuries which happen when conductors are accidentally short-circuited.

2. In some common cases some work may need to be carried out at the customers home and this can be potentially dangerous because the worker fixing the problem is in danger, and also any small children that may live in the house are also at risk.

In the customer’s home

1. When working in a customers home, the person carrying out the testing should carry out a site risk assessment to establish the steps required to create a safe working atmosphere.

2. Make sure everyone in the home is aware of the dangers arising from the testing work, and that they follow any precautions that are necessary. Ask for children and pets to be kept from the area

In the workshop

  1. Access to the area in where the appliance is being tested should be restricted as far as possible to the experienced employee carrying out the testing. Suitable barriers may be provided to help prevent unauthorised entry. Experienced employees must have sufficient knowledge of the electrical dangers connected with the appliances and the precautions necessary to reduce the risk of electric shock.

What precautions do I need to take?

Anywhere possible, the work should be done with the equipment dead, if not, adequate precautions, which should be acknowledged in your risk assessment, must be taken to certify safety.

What are the legal requirements?

The Electricity at Work Regulations 1989 is the principal legislation relating to electrical testing activities and regulation 14 is particularly relevant to live testing activities. In addition, employers are required under regulation 3 of the Management of Health and Safety at

Work Regulations 19997 to assess the risks to the health and safety of their employees while they are at work, in order to identify and implement the necessary precautions to ensure safety.

Laptop Repair

In this practical we looked t a laptop which had a laptop brought in which had too much space of the hard drive used. We had to research on the internet to find out if we could restore all of the factory settings back onto the laptop without using CD's. Before this could be done all of the settings and files had to be backed up onto an external hard drive. After this was done the factory settings could be restored and the hard drive memory could be freed up.
