Topic #: 2

A technician is trying to fix a computer that fails to boot even when all the RAM is removed. Which of the following should the technician do next to troubleshoot the issue?

AInspect the motherboard for swollen capacitors.

BReplace the CMOS battery_

CSwap the power supply if it is inoperable.

DCheck to see if the HDD power connectors are well seated

Show Suggested Answer

Suggested Answer: C

When a laptop screen fails to mirror to a television despite being correctly connected via an HDMI cable, a common issue is that the television is set to the wrong input source. Modern televisions have multiple input options (e.g., HDMI 1, HDMI 2, AV, etc.), and selecting the correct input that corresponds to the port the HDMI cable is connected to is essential for displaying the laptop's screen. The blinking logo on the TV screen typically indicates that the TV is functioning but not receiving a signal from the selected input source. Changing the TV's input to the correct HDMI port should resolve the issue and allow the laptop screen to mirror onto the TV. Reference: Hardware 1101.docx, 'Connecting External Displays' section.

D seems like a bit of a stretch here. If the computer can't even boot, I doubt the HDD connectors are the issue. But hey, you never know!

Haha, C made me chuckle. Swap the power supply? That's like the IT version of 'Have you tried turning it off and on again?'

Hmm, B is an interesting option. The CMOS battery could be dead, preventing the system from properly initializing. Worth a shot, I suppose.

But what if it's not the capacitors? Shouldn't we also check the HDD power connectors?

A is the way to go! Swollen capacitors can definitely be the culprit when a computer refuses to boot even without RAM. I've seen this issue a few times in my career.
