HP Recommended
Product: HP probook 4540s

I have an HP probook 4540s computer. The machine has worked as a so-called second machine. However, now there have been major problems. The machine starts up, but nothing else happens, and the Caps Lock button light flashes continuously. After a while the fan speeds up, then I turn off the machine. Sometimes, however, when I press the letter B during startup, I get to the boot menu, from which I go to the BIOS. I select “default settings” in the BIOS, and the machine starts up normally. The machine also works normally. Next time when I start it up, the machine does not work again. Almost always when I pressing the letter B during startup it does not work. Is the machine lost?
