Hp probook 450 g3
Microsoft Windows 10 (64-bit)
Hello,

So my laptop has been acting strange recently. When i try to start it up the screen remains black. It first starts with a beeping code (1 long, 1 long, 2 short) and repeats this about 5 times. After that the capslock button and the numlock button blink the same way and the fan starts running very loudly. I tried multiple things (connecting to an external display to see if it shows anything, windows+b key, a so called 'hard reset', pressing f8/f10 on startup to get to save mode/the bios screen) and tried looking for this beeping code on the forums, but i couldnt find it anywhere. I hope anyone here could help me out.

piggybacker

please start your own post and not steal others.

post your service tag model fully

and what OS its running now.

do not thing others fixes are your fix.  PCs are complex.

but one common fix is true

the F11 key

 

(if the HDD/ssd is still good

you go back to day 1, new in the BOX HP PC, as it came)

and most times all data gone and all apps gone

but sometimes not W10

 

NO warranty answers by me.

black screens 100% first REMOVE THAT big battery ! yet?

if BIOS screens are dead,  forget windows. if BIOS F9 is dead, for get all boots, possible

 

next try all BIOS keys, ESC and F9 , F9 is the slective boot mode. window, BIOS presents.

dead is dead, got  you covered.

 

next clean the vents, with con-o-air, sold all stores selling PC supplies.. if it can't breath it will overheat FAST.

(1:winkey+B,2:power on, then 3: release power) long 3 minute odd LED dance and   and BIOS recovery  screen shows, up, hit continue)

some PC benefit from hit power button for 10sec. with battery and AC line pack removed, aka HARD RESET.

for PC lacking battery pull there is special complex answer at HP.com

others find pulling the COIN cell battery helps.

 

 

keep in mind OP

this is W10 not w7

the safemode works using a totally different way,  and is 2  different ways,  from inside "msconfig" (run box)

and the magic way, I call it, if the PC keeps failing to boot over and over it goes to safe mode restore.

The PC can tell its sick after I think 2 hard fails to boot, and goes to recovery mode

or you go force it there,  on that set of screens blue are, startup settings, on that  screen is safe mode. burried deep.

F8 was to easy and fun so Gill Bates ended that...just for kicks.

 

 

 

last resort. (or to find safe mode or to run startup repair)

power off for 15sec. turn on and hammer F11, like a spam bot.(Wood pecker bird)

F11 key , activates, Recovery mode,  from the recover partition on the SSD.

 

Do not flash your BIOS.
