Pavilion dv6-3040sa, black screen, flashing caps lock
Processor failures can be have inconsistently. I have seen processor failures start with 1-2 second hangs in the OS to working one day and not at all the next.
hey mate.. ive got the same issue.. is it an issue with the cpu.
The blinking code you have desribed is a beep code of one. Review the following table found here.
|Caps Lock/Num Lock||1||CPU||CPU not functional||Reseat replace CPU.
|Caps Lock/Num Lock||2||BIOS||BIOS corruption failure||Restore BIOS from onboard backup (jumpers)
|Caps Lock/Num Lock||3||Memory||Memory module error not functional||Reseat memory modules (see next section).
Test memory from UEFI or BIOS.
Replace bad memory modules.
|Caps Lock/Num Lock||4||Graphics||Graphics controller not functional||Service|
|Caps Lock/Num Lock||5||System board||General system board failure||Service|
|Caps Lock/Num Lock||6||BIOS||BIOS authentication failure||Restore BIOS from onboard backup (jumpers)
The options for a blink code of 1 is to reseat the CPU as you have already done or to replace the processor. Since the issue returns after reseating the CPU, it looks like the CPU needs to be replaced.
