Explanation / Answer

Lab Analysis Test:

1) As Lenovo thinkpad T500 notepad supports $gb of RAM maximum, So Bill must buy another 2gb of RAM to to use the maximum RAM supports the system.

2) Teresa needs to change the Standby time to stop the system shut off automatically by itself.

She can do this in the followinf way:

a) Open Power Options in Control Panel.

b) In System standby, click the time you want.

3) Too much use of battery (constantly seeing the DVD's on his way) causes the battery running out of juice.

In this scenario, I would reccomend Maanit to on the Hibernate mode so that much much less power would consumps by the system.

4) Most expensive upgradable part in laptop is Hard drive; Most inexpensive part is battery.

5) In 'Always On' scheme, by default, monitor will turn off after 20 minutes. So the LCD screen will be shut down but the hard drive will be in on state, so that we can access the previous step when we will be needed.

Key Term Quiz :

1) The amount of time the Hard drive will continue to spin once it's no longer being accessed is determined by the Hibernate setting in windows XP and advanced power setting in windos vista/7.

\Hibernate mode is very similar to sleep, but instead of saving your open documents and running applications to your RAM, it saves them to your hard disk. This allows your computer to turn off entirely, which means once your computer is in Hibernate mode, it uses zero power. Once the computer is powered back on, it will resume everything where you left off.

2) You can use the Power Scheme applet in the control panel to set the power conservation options for the notebook computer.

\ By using Power Scheme applet, we can set up the power conservation in diiferent modes.

3) The battery, Hard drive, Memory all are upgradable laptop components.

\ if a Hard drive is given of 500 gb with the laptop and we are not pleased with that, definitelty we can upgrade the hard drive from 500gb to 1/2 tb. Similarly we can also upgrade the memory (RAM) from 2 gb to 4/8 gb according to our needs.

4) The amount of power remaining in battery can determined by looking at the Power meter.

\ Power meter is useful to know the amount of power remains in battery

5) Software can control power consumption if Standby is turned on in the CMOS setup program.

\ Standby is a more traditional sleep mode, as it reduces the power your computer uses to almost nothing. When you select Standby, the power to your screen, hard drive, and peripheral devices is cut. However, the power to the computer's memory (RAM) is maintained so your open files stay open.
