Given 's notes (HP Pavilion shows the vendor logo, BIOS is reachable, external boot appears blank), the firmware is completing POST but failing when control is handed to a boot device or OS loader. That narrows the likely causes to: a misdetected or failed internal drive, a boot-mode (UEFI/Legacy/Secure Boot) mismatch with the external media, faulty RAM, or a motherboard/IO-controller problem.

Suggested diagnostic sequence (do these in order to isolate the fault):

  • Power-reset the system: remove AC and battery, hold the power button 30–60 seconds, reconnect AC only and attempt boot. This clears stuck embedded-controller states (this relates to ’s battery suggestion but is quicker to test).
  • In BIOS, confirm whether the internal HDD/SSD is listed. Note model strings or absence of any SATA/PCIe storage entry.
  • Prepare a known-good bootable USB on another PC (make versions for both UEFI and legacy/MBR if possible) and set BIOS to match the USB mode (toggle Secure Boot/CSM/Legacy).
  • If the USB still will not boot, remove the internal drive and try the USB again. If USB boots with the drive removed, the internal drive or its connector is the likely culprit.
  • Reseat and test RAM modules one stick at a time in each slot; bad RAM can halt boot after the logo.
  • Observe POST indicators: beep codes, LED blink patterns, fan/spindle activity, or external display output. Run any HP built-in hardware diagnostics from the firmware menu and note error codes.
  • If the internal drive is suspected dead, remove it and check on another machine via SATA-to-USB to read SMART data and recover files.

If none of the above yields progress, the fault shifts toward motherboard/EC failure and professional repair is recommended (or HP service if under warranty). Record any error codes or blink/beep patterns — they are the most useful clues for a technician.

Had a similar problem with my hp laptop as well. My battery no longer held a charge so I ended up replacing it in the end. But before you insert the new battery, removed the old one, hold the power button down for a full minute,release, insert the new battery and let it fully charge.
