HP 14-ac146tx

[Jono01]

My laptop suddenly went shutdown. When i try to turn on again, the display was blank and capslock blink 2 blink.

when i turn on the laptop :
1. Cpu fan spinning fast for some second like usual.
2. Then the fan become too slow for 4 - 5 second.
3. After that capslock light blink 2 blink and cpu fan spin faster again.

My laptop type was hp 14-ac146tx core i3 5005 and have another amd gpu. I read on community hp that capslock blink 2 blink was bios problem. Try to recovery bios but the driver download page for hp 14-ac146tx was empty. I search that my laptop motherboard SKITTL10-6050A2730001-MB-A01 same as hp 240 g4 and 246 g4. I found bios link on ftp hp softpaq. Version F.1F and 2.1A. I try making usb bios recovery and then hold press win + b or b key but didnot work still blank display. The usb recovery bios has 4 tipe bin file inside folder. 080BB.bin, 080BD.bin 080BF.bin and 08132.bin. i do not know which the right bios for my laptop.

I think i upload wrong bios because when i try to compare the bios with post #9 080BD on tinyhexer are same. I think file bios backup is gone.

Use 0808BB.bin stil get capslock blink 2 blink same as before.
- Push power button fan spin faster for 4 second, the display on but blank.
- fan spin very slow or stop for 10 second and display look off on for one time.
- fan spin faster again and caps lock blink 2 blink.
the duration are 1,5 second blinking then 2 secons off and then blinking again for 1,5 second then 2 second off.

Because 080BB are for 5th gen intel where 080BD are for 4th gen intel, and 080BF are for 6th gen intel if i look the microcode with uefitool ne. So for 14-ac146tx that have i3 5005u proccessor the correct bios are 080BB. But the result is still same as before.

080BD.bin Haswell HSW/LPT-LP
080BB.bin Broadwell BDW/WPT-LP
080BF.bin Braswell/Cherry Trail BSW/CHT

080BD.bin Haswell HSW/LPT-LP
080BB.bin Broadwell BDW/WPT-LP
080BF.bin Braswell/Cherry Trail BSW/CHT

Yes. My laptop processor is core i3 5005u. It is broadwell. But flash with 080BB still have 2 blink caps lock and blank display.

The HP usb bios recovery does work. Keep trying! I had the same problem with 2 different laptops. What ended up working was using a usb 2.0 drive (i don't know if this is the cause) and keep holding the windows and B keys for more than a minute.Maybe hold it for several minutes. Nothing happens on the screen. Then I came across this:

"If the HP BIOS Update screen is not displayed, press and release the power button, and then immediately press the Windows + b keys at the same time, repeatedly, until the computer beeps or opens the HP BIOS Update screen." I kept pressing power and then windows and b keys and the screen finally flickered momentarily and then the bios recovery screen finally came up. You will hear a change in the fan speed.
