    HP Caps/Num Lock Blinking 3 Times

    Has anyone had any experience with a HP Laptop that:

    Powers on
    Blank Screen (same on the external)
    Caps/Num Lock blink 3 Times / stop for few seconds and repeat.
    After a little while the fans speed up.

    I have tried hard reset, changing the memory and removing all the detachable components.

    Thanks in advance.

    As you can verify with google search this sequence should be memory issue.
    If you tried to change the memory without result, first try the bios, even there is a code for this problem.

      Thank you for your reply. I have tried different memory but the problem didn't go away. I think I am just going to replace the motherboard.

        If I remember correctly, I have fixed HP-s with such fault by reprogramming bios IC.

          Flashing the BIOS is definitely worth a try

            Then why you posted here if you are not even willing to try. As other members have said, bios flash will solve your problem-there is great chance.

              probably he doesn't have the knowledge or the equipment to do it, except some cases may not be possible through software

                Equipment cost is around 10€ from Ebay.

                  HP Elitebook 845 G8 dead, only caps lock flashing 7 times. Charging light always on
                  by esqmooo
                  Hello everyone.

                  This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
                  Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
                  Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
                  I tried long pressing on the power button, after several seconds it would go off then when the button is released...

                  HP Elitebook 850 G8 CAPS lock flashes 7 times and charging light always on
                  by esqmooo
                  Hi,
                  I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.

                  Caps and num lock blink 4 times
                  by AdrenalinTL
                  I am sitting with a very similar issue.

                  Basically, had a probook that worked, gave it to someone, they returned it DOA. what the heck happened, I have no idea.

                  Caps and num lock blink 4 times, as per HP, thats a board failure. I am very new to this, so perhaps I should be posting a new thread?

                  Anyway, I resoldered the bios chip on after trying EVERYTHING else including reseating ram, cpu etc.

                  Multimeter shows 19.5V on power, so I presume thats correct. Fan spins, no display. No post. Bios chip looks good from what I can tell just not sure how...
