doctors have recommended the use of light boxes a couple hours a day for people
who suffer from Seasonal Affective Disorder (SAD). People with SAD are
negatively affected by long dark winters, and light boxes can be used to
lighten the day. If you want to try this form of therapy, it is most effective
to use a light that will be similar looking to natural daylight.
yes you can but just to be sure that it's gonna be compatible to your computer's hardware components, check it online. try going to HP's website and look for the manual or specs of your computer. they usually have motherboards for sale also online. it's better to be sure or else you might encounter compatibility issues. try calling also to their technical support, they can assist you in looking for the perfect motherboard. If it is for gaming purposes, you better upgrade your videocard and memory modules as well.
have a great day!
types of Computer According to Operation. There are three basic types of computer according to their operation: 1. Analog Computers. 2. Digital Computers. 3. Hybrid Computers. 1. Analog Computers: "Those computers which are used for measuring of physical quantities are calledAnalog Computers". Analog means variable and physical quantity always changes. "Those computers which measured analog type of data are called Analog Computers" These computers accept input in analog form and provide an analog output of information. It represents physical quantities like distance, velocity, acceleration and temperature. It measures continues changes in physical quantities. e.g. speedometer of a care, temperature, needle's watch for measuring the time, volt meter for measuring voltage. Now a day analog computers are using for Engineering and Scientific works. In Oil Refinery measures flow and temperature of oil. They are also used in Paper making and Chemical Industry. Out put of the analog computer is generally in the form of readings. These computers are dial in situation where data can be measure directly from measuring instrument without having to convert into numbers or codes. Now a day Analog Computers are proceed to Digital Computers. For example: Analog watch to Digital Watch, Analog Balance to Digital Balance and Analog Thermometer to Digital Thermometer etc. 2. Digital Computers: "Those Computers which accept digital input and provides information in digital form are called Digital Computers". "Those Computers which measure in term of digital quantity are called Digital Computers". These computers works on the base of binary digits i.e. (0 & 1). The results of the Digital Computers are more accurate, precise and reliable then the result of Analog Computers. Digital Computers are faster then Analog Computers. Analog Computers lack memory while Digital Computers store information. Accounting machine and Calculator are the common example of Digital Computer. Now a day Analog Computers are proceed to Digital Computers. For example: Analog watch to Digital Watch, Analog Balance to Digital Balance and Analog Thermometer to Digital Thermometer. 3. Hybrid Computers: "Those Computers which accept digital inputs and provides outputs in the form of analog and vice versa". Hybrid Computers have the characteristics of both Analog & Digital Computers. It is the computer which measures both the analog and digital quantities. It combines the both features of analog and digital computer. Hybrid Computer has process with the speed of analog and accuracy of digital computer. They are used for special purpose. These are designed to perform special task. For example ECG machine. Hybrid Computers are also used in Air Defense System. Data Communication and Transmission and in different laboratory for medicines. Basically computer has two types according to their function. 1. Special Purpose Computers: 2. General Purpose Computers: 1. Special purpose Computers: "Types of computers which are manufactured for specific task are called Special purpose Computers". These computers are also known as "Dedicated Computers" because these are designed for special jobs. In other words they are designed to handle specific problems. e.g. they are used in Computer Games, Control of Traffic Lights and in Defense System. A set of instruction permanent program feed to them. As they have to perform only one job so they are very fast.
2. General Purpose Computers: "Types of Computers which can perform all types of jobs and can run all types of programs are called General Purpose Computers". Those computers are performing variety of jobs and use for General Purpose. For example with a personal computer a user can perform typing, can play games, can make graphics and can do arithmetic operations. General Purpose Computers are versatile but they are slow in processing and less efficient as compare to Dedicated Computers. Classifications of ComputerClassifications of Computer Computers are classified into different categories according to their physical size, cost and speed. We can general classified them into 05 categories. (Classifications of Computer) 1. Very Small (Micro Controllers) 2. Small (Micro Computers) 3. Medium (Mini Computers) 4. Large (Mainframe) 5. Very Large (Supper Computer)
You need to remove the trys affected, most likely there is a sensor issue.
Remove the trays and check behind them as paper sometimes falls behind blocking the sensors. If so, remove the paper.
Also, check the paper slides in the tray themselves, remove the paper and slide them in and out all the way, put the trays back in the machine and put the paper back in the tray moving the slides right up against the paper and close the door. It should work normally from now on, if not try a reboot one more time.
try unplugging the power cable, holding down the power button for 10 seconds, then plugging it back in and turning it back on. also, there should be a set of 4 lights on the back of the dell (A, B, C, and D) for diagnostic purposes. Check them and compare them to your model's light diagnostic look-up on Dell's website.
