Troubleshooting the HP EliteBook 840 G5: Caps Lock and F10 Blinking Issue

Hello readers,

If you own an HP EliteBook 840 G5 and have encountered a frustrating situation where your laptop refuses to power on, you’re not alone. One common indication that something’s amiss is when the Caps Lock and F10 keys start blinking seven times when you attempt to turn the device on. Unfortunately, the screen remains black, and you’re met with silence—no fan noise or any other indicators of life from your laptop.

Recently, I found myself in this predicament and have taken some initial steps to troubleshoot the issue. I attempted a basic reset by holding down the power button for a significant duration, but to no avail; the blinking keys persisted and the laptop remained unresponsive.

The seven blinks are likely a diagnostic code indicating a specific issue with the hardware. While I’m not a tech expert, I’m reaching out to the community in hopes of shedding light on potential fixes or further insights into what the blinking pattern could signal.

If you have experienced this problem or have expertise in HP laptops, your guidance would be immensely helpful. Any tips, recommendations on what to try next, or explanations of the blink code would be greatly appreciated.

Thank you in advance for your assistance!
