T450 BEEPS, wont turn on, after enabling secure boot

Beep code is

 

1-3-3-1 (i.e. beep, pause, beep 3x, pause, beep 3x, pause, beep)

 

All beeps are short I guess

 

Laptop is a handme down which came with no hard drive

 

It has 16GB of RAM

 

I was playing around with BIOS settings and changed a bunch of stuff:

 

    I disabled wifi / bluetooth / mic, enabled secure boot, I did not reset the secure boot keys

 

After that I had the problem

 

I pulled out main battery and internal battery, held the power button for 60s or more

 

I pushed the emergency reset button using paperclip

 

Problem not solved

 

Manual says that that beep code indicates a memory problem and to have the computer serviced

 

Any tips on how I can do that myself?

 

Thanks!

Do you have 2 memory sticks or 1?  If 2 (2 x 8gb) try them one at a time

Yes, 2 memory sticks

 

I tried:

  • No sticks
  • Left stick only, in Left Slot
  • Left stick only, in Right Slot
  • Right stick only, in Left Slot
  • Right stick only, in RIght Slot

 

In all cases I got the same symptoms

 

I cannot access BIOS settings anymore, or any diagnostic screen for that matter

 

Previously I had ran memory tests and CPU tests, pretty much all hardware tests available in some diagnostic screen, and they all passed, except one which I didn't finish running since it took so long

 

However, during the memory test only 8gb was showing up I think
