HP Laptop Error 601 — Battery Replacement Alert

What Does This Error Mean?

Error 601 means the internal battery has aged enough that HP recommends replacement. The laptop will still work but battery runtime will be poor. Replacement is straightforward on most HP laptop models.

Affected Models

HP Pavilion
HP EliteBook
HP ProBook
HP Envy
HP ZBook
HP Spectre

Common Causes

Battery cells worn out from age and charge cycles
Battery capacity dropped below HP's minimum threshold
Battery internal sensor fault
Damaged battery from overheating or physical impact

How to Fix It

Press F2 to continue past the error.

The error appears at boot. Pressing F2 lets you continue to Windows. The laptop will still run on AC power and will charge to whatever capacity the battery can still hold.
Check battery health in HP Support Assistant.

Open HP Support Assistant in Windows and go to Battery Check. This confirms the battery state and shows the estimated remaining capacity.
Order a genuine HP replacement battery.

Use your laptop model number to find the correct battery part. Genuine HP batteries are recommended — third-party batteries can trigger ongoing 601 errors or have shorter life.
Replace the battery.

On HP laptops with a user-removable battery, slide the latch and swap the battery. On laptops with internal batteries, follow HP's service guide for your model — typically removing the bottom panel.

When to Call a Professional

If your HP laptop has an internal (non-user-replaceable) battery, a technician can replace it. Most modern HP EliteBooks and Spectres require partial disassembly.
