Re: Compaq CQ58-d33SZ Caps Lock blink 3 times
Among 4 dead laptops I am trying to fix, currently i am typing on HP which always blinks caps+num lock every time when I power it on. all started when cooler worked poorly and 2 times experienced shut down due overheating.
point is that I left it once blinking and after a minute or two laptop just started loading os.
I replaced cooler, cleaned memory, and processor. still blinking, but after a minute or two laptop working. maybe you can give a try to wait for a few minutes. then measure.
just amateurish tip...Comment

The measurements are not visbile clearly after zooming in on pic. better you write here pin voltages.Comment

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... -
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... -
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.03-07-2025, 05:55 AM -
I have hp 15-ac126tu And after turning on caps lock blink 3 times and repeat after a while. On hp website i can read that this is ram problem so i changed the ram modules for surely working ones and still no results - 3 blinks anyway.
This laptop use ddr3l but i even checked the normal ddr3 and same result.
All voltages are present, screen only goes black(polarization).
I've tried to reprogram bios too, same result.
Under the thermal cam i can see that the cpu have hot spot, should i be sure that this is problem with this hybrid cpu/pch?
Cpu coil is around 16-20... -
Hi guys, I have an HP model 15s-eq1040nl main DAOP5FMB6A0 REV:A with a caps/lock 5 long 3 short led flashing problem, I tried to remove the battery and program a new bios and when I restarted it immediately worked correctly, the pc turned on and loaded the operating system.
As soon as I turned off the pc and connected the battery, the problem reappeared... caps/lock 5 long 3 short led flashing again!
the battery was dead, i charged it and it works fine, but the pc won't turn on again.
What do you recommend me? Do I have to redo the bios or is there anything else to check?...
