Exam 220-1101 topic 1 question 153 discussion

If the computer is not completing POST and is stuck at the manufacturer logo screen even after disconnecting all internal and removable parts, then the next step would be to test the RAM in different slots, one at a time. This is because the issue could be due to a faulty RAM or a bad memory slot. Testing the RAM in different slots will help in identifying the faulty RAM or memory slot. If the issue is not with the RAM, then other hardware components such as the power supply, motherboard, or CMOS battery may be the root cause of the problem. However, trying to replace the motherboard or the power supply without proper diagnosis can be expensive and time-consuming. Therefore, it is best to start with the simplest and most common troubleshooting step of testing the RAM.

a faulty or inadequate power supply can cause a computer to not complete the power-on self-test (POST) and get stuck at the manufacturer logo screen. The power supply is responsible for providing stable and consistent power to the components of the computer, including the motherboard, CPU, RAM, and other peripherals. If the power supply is not working properly, it can cause issues with the computer's boot process and prevent it from starting up correctly. The question stated, "All internal, removable parts have been disconnected ." Therefore, I believe that the technician has done A and D already.

I think A is the answer Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won’t be able to save any settings in the BIOS, which includes the date and time. If your PC is not booting after removing CMOS, you need to make sure that you have your CPU and RAM connected because it’s not possible for your system to boot without those.. Your motherboard and computer will be able to boot just fine even without a CMOS battery present. The only issue is all your BIOS settings will be reset and the time and date will be inaccurate. You will also be unable to save BIOS settings.

B. The most likely culprit for a system stuck at the manufacturer logo screen after a minimal hardware configuration is a faulty power supply unit (PSU). Therefore, the technician should B. Remove and test the power supply. If the PSU is functioning correctly, then the issue could be related to the motherboard or RAM. However, since the system is not even reaching the BIOS, a power supply issue is more likely. Google Gemini

In real life troubleshooting, always go with easiest then the gradually complicated steps. Removing the RAM is reasonable to be removed and tested. If than doesn't work, then go with the power supply.

B. Remove and test the power supply. Issues with the power supply can cause a computer to fail during POST or get stuck at the manufacturer logo screen. Testing the power supply involves either replacing it with a known good one or using a power supply tester to check its functionality. While testing the RAM in different slots (option A) is a good troubleshooting step, it may not be the immediate next step if the issue persists after minimal parts are connected. Replacing the motherboard (option C) is a significant step and should be considered after ruling out other possibilities. Changing the CMOS battery (option D) is generally not the first step in troubleshooting POST issues unless there are specific indications of CMOS-related problems. Therefore, testing the power supply is a logical next step to identify or rule out potential power-related issues.

One of the first things to check that is required to POST is the ram. If the slot is messed up or if the stick is faulty the pc will not POST.

B. Remove and test the power supply. When a computer gets stuck at the manufacturer logo screen during POST, it could be indicative of power-related issues. If all internal, removable parts have been disconnected, and the minimum necessary components have been reconnected, the next logical step is to test the power supply. A faulty power supply can lead to various issues, including the system not completing POST. Testing or replacing the power supply can help rule out or identify power-related issues before considering more drastic measures like replacing the motherboard or other components.

Your computer might be unresponsive during the startup process when your RAMs are not well installed, or in some cases, one or more of your RAM modules or RAM slots is faulty.

the correct answer is D

I think is C

as i'm reviewing these answers , i actually tried this with old dell OptiPlex 990, old Junker i have but still runs, but anyways,, i pulled out the cmos battery and the Dell boated up just fine, so i'm going to go with option A.

The power supply is the most crucial unit of the PC because it can burn hardware, RAM is a temp memory crucial for running apps and software smoothly. In that case scenario and any other, I would always check the Electrical Device that is a Heart of the Computer, the middle man between electrical energy and the actual device. Without electrical power, no PC can run !!! In addition to that electrical energy has the capacity to burn hardware. The most crucial - check first. I know that the freezing screen of the logo might indicate a RAM. But Power supply is the most crucial part of the PC. I would check it first !!!

This was on my exam and I didn't miss anything in this objective, so the answer is A. Test the RAM in different slots, one at a time.

The correct answer is A. a dead CMOS battery will not prevent the PC from posting.

The technician can also test the power supply and change the CMOS battery as a NEXT step if the issue still persists after testing RAM. therefore answer is A

A =ANSWE. Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won’t be able to save any settings in the BIOS, which includes the date and time.
