HP ProBook: Budget Line vs. EliteBook
ProBook and EliteBook are both HP business laptops, but they differ in level and design.
ProBook — Not a Budget Version of EliteBook
Although both lines target the business segment, ProBook (450, 650, 6570b, etc.) uses different components than EliteBook from the same period — it's a parallel line, not a simplified version of the same model. Parts between ProBook and EliteBook are almost never interchangeable.
Within the ProBook Line
Like EliteBook, ProBook has an older numbering system (6570b) and a newer one (450 G-series) — the same principle applies: the G-generation number is as important for part selection as the model itself.
A Common Customer Misconception
"ProBook and EliteBook are both HP business series, so their parts should be similar" — these are separate product lines with different internal designs.
