Lenovo ThinkPad SL500 review

Where the ThinkPad SL500 stands

The Lenovo ThinkPad SL500 is a business-class laptop priced at roughly $88 — among the cheapest machines in the dataset and well below the $248 category median. The release year is not recorded, but the specifications (no USB-C, no discrete GPU, no recorded memory ceiling) place it in the 2008–2009 generation of entry-level ThinkPad hardware. At this price point the laptop competes more with embedded and single-purpose devices than with general-purpose laptops, and the buying decision should be made on that basis.

The performance floor

The defining specification on the SL500 is performance: a performance-index score at the absolute floor (0) against a category median of 43, with similar scores for GPU and CPU capability. This is not a laptop that can be characterised as "slow but usable" — it is a laptop where the performance gap to any modern alternative is wide enough that the user experience will be defined by it. Single-task document editing and offline text work remain feasible; anything involving a modern web browser, video playback, or multitasking will be materially constrained.

What justifies the price

At $88, the SL500 is not sold as a general-purpose laptop — it is priced as a parts donor, a collection-piece for ThinkPad enthusiasts, or a single-purpose terminal. The ThinkPad keyboard and chassis build remain genuinely good even by modern standards, and the laptop has no axis where it meaningfully exceeds the median. The honest framing is that the SL500 has residual value as a built object, not as a working computer in any modern sense.

How it compares

In the sub-$100 segment, the SL500 competes with the HP Compaq CQ57 ($98) and Lenovo B590 ($100) upward, and the HP Pavilion g6-1312sr ($82) downward. All three alternatives are 2011–2013 vintage machines with similar performance constraints and similar feature sets. The SL500 does not stand out in this peer group on any measurable axis — its only differentiator is the ThinkPad badge and the keyboard quality associated with it, which is a real but narrow consideration.

Bottom line

The ThinkPad SL500 at $88 is a budget-friendly pick only in the narrowest sense: for a buyer who specifically wants a ThinkPad keyboard, a parts donor, or a single-purpose offline terminal. For any general computing use, the performance floor is too low for the laptop to be a defensible choice in 2026 over a slightly more expensive but vastly more capable alternative. The price is honest for what the laptop is; what it is, is a seventeen-year-old machine with residual value as a built object rather than as a working computer.
