5. What type of notebook internal components may require you to remove the keyboard before replacing that component?
6. How do you fix common problems with a notebook touchpad?

Answers

Answer 1

Answer:

1. Best way is to get the manual from the manufacturer.  Each manufacturer places the laptop components in different locations and have different methods of securing the components.  Dell does a great job in publishing a manual for repair of each component with detailed locations and step-by-step instructions.

2..  You can use an external monitor to test this - assuming the laptop has a external connection (HDMI, DisplayPort, VGA).  If the external monitor works, you know the laptop's monitor is the problem.  If the external monitor does not work it is likely the display adapter.

3. Failed internal input components can be substituted using external devices.  The laptop will have USB connections that can be used for mice, keyboards, network cards, sound cards, and monitors.

4. The main thing to ensure for compatibility is the I/O bus type.  SATA / ATA / IDE (older) must be matched to ensure the new drive will work.  Look on the label of the old drive to see the specifications.  Most modern laptops will user SATA as the I/O connection - both solid state drives and traditional platter based.  As long as the I/O bus connection works, you can modify the speed and capacity of the drive with no major issues.

5. It depends on the model, but the majority of the internal components will require removal of the keyboard for access.  This includes the system board, video card, network card, sound card, and hard drive.  Memory is the one component that the manufacturer will often allow for replacement / addition through an access port on the bottom (but not every manufacturer does this - i.e. Apple)

6.  Touchpad problems can be the result of foreign material on the pad (grease, oil, etc), or damage to the pad surface.  If cleaning the pad thoroughly or rebooting the computer does not help then you might be looking at a component replacement.  Resetting the device drivers can also be attempted.

Given that arrayIntValues [MAX_ROWS][MAX_COLUMNS] is a 2 dimensional array of positive integers, write a C++ function howManyEven to find the total number of even elements in the array. It should have input parameter array arrayIntValues. The function should return an integer.

Answers

Answer:

Follows are the method definition to this question:

int even(int A[MAX_ROWS][MAX_COLUMNS], int length,int width)//defining a method even,that accept 2D array and two integer variables  

{

int E_num = 0;//defining an integer variable E_num that holds a vlue 0

for (int i = 0; i < length; ++i)//declare for loop for row count

{

for (int j = 0; j < width; ++j)//declare for loop for column count

{

if(A[i][j]%2 == 0 )//use if block that check even number in array  

{

E_num++;//incrementing the value of E_num  

}

}

}

return E_num;//return E_num value

}

Explanation:

In the above code, a method "even" is defined, which accepts a 2D array "A" and two integers " length and width" in its parameter.

Inside the method, an integer variable "E_num" is defined that uses two for loop and an if block for the count the even numbers which are available on the 2D array.

4.11 LAB: Remove gray from RGBSummary: Given integer values for red, green, and blue, subtract the gray from each value.Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).Given values for red, green, and blue, remove the gray part.Ex: If the input is:13050130the output is:80 0 80Find the smallest value, and then subtract it from all three values, thus removing the gray.Note: This page converts rgb values into colors.LAB

Backtracking is a general algorithm for finding all (or some) solutions to some computational problem, that incrementally builds candidates to the solutions, and abandons each partial candidate c ("backtracks") as soon as it determines that c cannot possibly be completed to a valid solution.

Given that arrayIntValues [MAX_ROWS][MAX_COLUMNS] is a 2 dimensional array of positive integers, write a C++ function Even to find the total number of even elements in the array.

It should have input parameter array arrayIntValues.
A[length][width]
Length
Width

The function should return an integer. Also create a C++ subroutine called printArray with the input parameter array.

Answers

Answer:

Here is the C++ program:

#include <iostream>  //to use input output functions

using namespace std;   // to identify objects like cin cout

const int MAX_ROWS=3;  //sets the maximum number of rows to 3

const int MAX_COLUMNS=2;  //sets the maximum number of columns to 2

//function prototypes

void printArray(const int array[MAX_ROWS][MAX_COLUMNS]);  

void Even(const int arrayIntValues[MAX_ROWS][MAX_COLUMNS]);

int main(){  //start of main method

    int arrayIntValues[MAX_ROWS][MAX_COLUMNS];   //declares a 2D array of integers

    cout<<"Enter elements of 2D array: ";  //prompts user to enter integers in a 2D array

    for(int i=0;i<MAX_ROWS;i++)  {  //outer loop to iterate through rows

               for(int j=0;j<MAX_COLUMNS;j++) //inner loop to iterate through columns

               cin>>arrayIntValues[i][j];  }   //reads and stores integers in 2D array

Even(arrayIntValues);  //calls Even method by passing arrayIntValues

printArray(arrayIntValues); }   //calls printArray method by passing arrayIntValues

void Even(const int arrayIntValues[MAX_ROWS][MAX_COLUMNS]){  //method that takes an array as parameter and finds the total number of even elements in the array

    int count = 0;  //counts the number of even numbers in array

       for(int row=0;row<MAX_ROWS;row++){  //outer loop iterates through rows of the array

               for(int col=0;col<MAX_COLUMNS;col++){  //inner loop iterates through columns of the array

               if(arrayIntValues[row][col]%2==0 && arrayIntValues[row][col]>=0)  //if the element at specified index of 2D array is an even number i.e. completely divisible by 2 and that element is positive

                               count++;   }        }  //adds 1 to the count variable each time an even positive integer appears in the array

       cout<<"total number of even elements in the array: "<<count<<endl; }   //displays the number of even element in arrayIntValues

void printArray(const int array[MAX_ROWS][MAX_COLUMNS]){  //method that takes an array as parameter and displays the even numbers in that array

       for(int row=0;row<MAX_ROWS;row++){  //outer loop iterates through rows of the array

               for(int col=0;col<MAX_COLUMNS;col++){  //inner loop iterates through columns of the array

                       if(array[row][col]%2==0 && array[row][col]>=0)  //if the element at specified index of 2D array is an even number i.e. completely divisible by 2 and that element is positive

                               cout<<array[row][col]<<endl;  //displays the even element of the array

                        else  //if element is not even

                        continue;                 }         }       }  //continues the loop to look for even elements

Explanation:

The program first prompts the user to enter elements in 2D array. It then calls Even method which iterates through the rows and columns of the array to look for the positive even numbers (elements) in array . Whenever a positive even number is encountered in the array, the count variable is incremented to 1. At the end the method returns an integer which is the total number of even elements in the array. Then the program calls printArray method which iterates through the rows and columns of the array to look for the positive even numbers (elements) in array . Whenever a positive even number is encountered in the array, that element is displayed on the output screen. The screenshot of the output is attached.
