HP Active Pen T4Z24AA#ABA

The HP Active Pen T4Z24AA#ABA is a digital stylus built for select HP touch-screen laptops and tablets. It delivers pressure-sensitive input with a fine tip that hovers above the display for precise cursor control. Two side buttons provide quick shortcuts, and an application launcher button opens chosen programs instantly. The pen runs on a single AAAA battery.

Upgrade from basic touch

This pen replaces finger input or a passive capacitive stylus when accuracy matters for handwriting, sketching or detailed annotation. The pressure-sensitive tip captures line-weight variation that a fingertip cannot, and the hover function lets you position the cursor without touching the glass. The jump is worth it for users who take handwritten notes, mark up PDFs or draw diagrams in Windows 8.1 or Windows 10.

Build fit and power

The stylus pairs directly with compatible HP devices — no separate receiver or Bluetooth pairing step is required. A AAAA battery powers the active electronics, so there is no charging cable to carry and no drain on the laptop’s USB port. The compact form slips into a pen loop or sleeve pocket, leaving all USB ports free for peripherals or storage.
