I have Dell 3542 . When I boot up my laptop it makes loud beeps of 5-5 counts and also my hdd short test is failing with error code 0142. I have tried re-installing OS and completely formatted hdd but problem remains.I don't know if beeps are related to hdd test fail. Also my caps lock led as well as Dvd-Cd disc reader led is not working . Can anyone help me?? Any help is appreciated.
Try restarting the system and tap F12 at start up once you boot into diagnostic please re run the diagnostic and share the error code and validation code. Please share the service tag of the system so that we can check with system specification, tell us what is the power button status on/off solid or flashing. For me to better assist in troubleshooting, please click my DELL-username and send me a Private Message with the Dell Service Tag number and your email address.
