How Long Do Laptops Last? Battery, Hardware and Software Support Years

By LaptopOwners · Updated · 10 min read

Most laptops keep working for five years or more, but “how long” depends on which part gives out first. The battery usually goes first: Lenovo’s own page puts a laptop battery at 2 to 5 years, and HP’s at 2 to 4. The software clock is often what ends a laptop for good: Google promises Chromebooks 10 years of updates, while a Windows laptop lasts as long as its hardware can run a supported version of Windows.

So split the question into three clocks: battery, hardware and software. A dead battery is a repair. A laptop that can’t get security updates any more is usually a replacement.

The three clocks at a glance

Batteries wear out over years, hardware fails at random, and software support ends on a published date.

Batteries wear out first: 2 to 5 years on makers’ own pages Horizontal timeline chart of laptop lifespan figures as makers state them, on a scale of 0 to 10 years. Battery: Dell says typical users notice reduced runtime after 18 to 24 months; HP says its batteries typically last 2 to 4 years or about 1,000 charge cycles; Lenovo says 2 to 5 years or 300 to 500 charge cycles. Parts and service: Apple calls a product obsolete, and parts can no longer be ordered, more than 7 years after it stopped selling it, and offers battery-only repairs on Mac laptops for up to 10 years, subject to parts. Software: Google gives Chromebooks 10 years of updates from the platform release date; the 2020 MacBook Air M1 is still on Apple’s list for macOS 27 Golden Gate in 2026. Windows has no year count; Windows 10 support ended October 14, 2025. Batteries wear out first: 2 to 5 years on makers’ pages Each clock as the maker states it. Start points differ, as noted in each bar. BATTERY PARTS AND SERVICE SOFTWARE UPDATES Dell battery HP battery Lenovo battery Apple parts Apple battery-only Chromebook MacBook Air M1 runtime drops at 18–24 months 2–4 yrs, about 1,000 cycles 2–5 yrs, 300–500 cycles orderable to 7 yrs after last sold up to 10 yrs after last sold, if parts allow 10 yrs of updates from platform release 2020 to macOS 27 in 2026 6+ yrs and counting 0 2 4 6 8 10 yrs Windows has no year count: support follows the Windows version. Windows 10 ended October 14, 2025, so the clock depends on whether the hardware meets Windows 11’s rules.

Clock 1: the battery

The battery is the part that wears out on a schedule, and every maker says so. Here are their own figures.

  • Apple rates recent MacBooks, from the 2020 MacBook Air M1 to the M5 models and the MacBook Neo, at a maximum of 1,000 cycles. Apple says the battery “is designed to retain up to 80% of its original charge capacity at its maximum cycle count” (Apple, published March 10, 2026).
  • HP says its “laptop batteries typically last between 2 to 4 years or about 1,000 charge cycles” (HP Tech Takes, bylined August 20, 2024).
  • Lenovo says “a laptop battery can last between 2-5 years or between 300-500 charge cycles” (Lenovo).
  • Dell says typical users “will likely notice a reduced runtime after 18 to 24 months,” and power users within 18 months. Dell batteries carry a one-year warranty, or three years where the spec says “Long Cycle Life” (Dell, modified October 12, 2026).

A worn battery doesn’t end the laptop. Apple says Mac laptops may be eligible for battery-only repairs for “up to 10 years from when the product was last distributed for sale,” subject to parts availability (Apple, published October 14, 2026).

One forum figure you’ll see a lot doesn’t come from any maker. A post on ElevenForum claims about 600 cycles at 100% charge versus 1,800 if you stop at 80%, with no source in the post we read. None of the maker pages above states it, so don’t plan around it.

Clock 2: the hardware

Hardware failure is the one clock nobody can put a date on. We couldn’t open a published reliability survey, so we won’t guess at failure rates or rank brands. What a maker does commit to is its warranty and how long it keeps parts.

Forum answers swing wildly because they’re anecdotes. On the Tom’s Guide forum in 2014, one moderator said two of their laptops still ran at 15 years old, while they’d seen others die in about six months. Another moderator said their own laptop’s motherboard failed after about seven years. On the Windows Central forum in 2015, answers ranged from “slows down after 3-4 years” to a decade or more.

What you can plan for is repair access. Apple calls a product vintage when it stopped selling it “more than 5 and less than 7 years ago” and obsolete after 7, and service providers “cannot order parts for obsolete products” (Apple). Check how long your maker’s standard warranty runs; our extended warranty guide compares the paid plans from their terms.

Clock 3: software support

Software support is the clock with published end dates, and for many owners it’s the one that decides when to replace. In a 2018 Tom’s Guide thread, a moderator said their 2003 ThinkPad still powered on in 2016 but couldn’t handle modern websites or video. Another reply put it simply: obsolescence and accidents usually arrive before anything dies.

Windows. Microsoft’s end-of-support page says “On October 14, 2025, Windows 10 support ended,” and that Microsoft “no longer provides software updates, security fixes, or technical assistance to Windows 10 PCs.” For home PCs, the consumer Extended Security Updates (ESU) program provides security fixes “through October 12, 2027, regardless of when you enroll.” Enrolling is free if you sync your PC settings, or costs 1,000 Microsoft Rewards points or a one-time $30 plus tax (Microsoft, read October 22, 2026). Work and school PCs use Microsoft’s separate paid commercial ESU, which can run “for a maximum of three years after end of support” (Microsoft Learn, updated November 17, 2025). After that, the only supported route is Windows 11, which needs a “compatible 64-bit processor,” 4 GB of RAM, 64 GB of storage, “UEFI, Secure Boot capable” firmware and “Trusted Platform Module (TPM) version 2.0” (Microsoft). Microsoft’s own advice for a PC that can’t upgrade is to stay on Windows 10 with ESU or buy a new PC.

Mac. Apple doesn’t publish a count of years, but its compatibility lists show the pattern. macOS 27 Golden Gate supports MacBook Air and MacBook Pro models back to the 2020 M1 models, plus the MacBook Neo (Apple, published September 14, 2026). The Intel MacBook Pros still on macOS Tahoe’s list, the 16-inch from 2019 and the 13-inch from 2020 with four Thunderbolt 3 ports, aren’t on it (Apple). Two years earlier, macOS Sonoma went back to the 2018 MacBook Air (Apple).

Chromebook. Google’s policy says “ChromeOS devices receive 10 years of updates,” counted “from the platform release date,” not the day you buy (Google). A Chromebook bought late in its platform’s life gets fewer of those years. Google’s advice: “Remember to check the date when making a purchasing decision.” Our Chromebook vs laptop guide covers what else a Chromebook can’t do.

Signs it’s time to replace, and what’s fixable

Battery problems and slowness are usually fixable. A laptop that’s lost software support, or needs a board out of warranty, usually isn’t worth it.

Sign Which clock Usually
Short runtime; Mac past its maximum cycle count, or Dell battery health “Fair” or “Poor” Battery Replace the battery
Shuts down with charge showing, or the battery swells Battery Stop using it on battery; replace the battery now
Slow on an old hard drive or 4 GB of RAM Hardware Fixable if the drive and RAM aren’t soldered
Board, screen or keyboard fault out of warranty Hardware Get a repair quote and compare with a replacement
Home Windows 10 PC that can’t meet Windows 11’s requirements Software Replace by October 12, 2027 (consumer ESU end), or sooner without ESU
Chromebook past its “Update schedule” date Software Replace
Mac not on the current macOS list, or Apple calls it obsolete Software, parts Replace when security updates stop or parts run out

The upgrade route can add years. In another 2018 Tom’s Guide thread, one owner said a 2011 ThinkPad T420 still ran well after an SSD and 8 GB of RAM.

Repair or replace: a checklist

A 2026 Tom’s Guide thread asked exactly this about an older Lenovo IdeaPad with a dead battery and slow performance, and the one direct reply was “depends on your budget.”

  1. Is it still getting updates? On Windows, check you’re on Windows 11 or enrolled in ESU. On a Chromebook, open Settings, then About ChromeOS, then Additional details, and read the Update schedule. On a Mac, compare your model with Apple’s list for the newest macOS. No updates coming means replace.
  2. Is the battery the only problem? On a Mac, hold Option, click the Apple menu, choose System Information, then Power, and read the cycle count. On Windows, run powercfg /batteryreport in a terminal; Microsoft says it reports “battery usage characteristics over the lifetime of the system.” If only the battery’s worn, replace the battery.
  3. Is it slow, or broken? Slow on a hard drive or 4 GB of RAM can be an upgrade, if the parts aren’t soldered. Broken boards are a repair quote.
  4. Is it under warranty, or can parts still be ordered? Check the maker’s warranty status, and on a Mac, whether Apple lists it as vintage or obsolete.
  5. Does the repair cost more than half of a replacement you’d be happy with? That’s our rule of thumb, not a maker’s. Price a like-for-like new or refurbished laptop first.

What it means when you buy

The longest-lasting laptop is the one whose software clock starts latest. For a Chromebook, check the “Automatic updates until” date in Google’s list before you pay, especially on discounted older models. For a Mac, a newer chip simply starts its run later. For Windows, every new Windows 11 laptop meets the requirements; with a used one, check for TPM 2.0 and a supported processor before you buy.

Check the cycle count on any used or refurbished Mac. Our guide to how much to spend on a laptop shows what each price tier gets you, and when to buy covers the sale dates.

FAQ

How long do MacBooks last?

Apple doesn’t give years, but its lists show it. macOS 27 Golden Gate, published September 14, 2026, still supports the 2020 MacBook Air M1, so that model was on Apple’s newest macOS six years on. Apple rates recent MacBook batteries at 1,000 cycles to 80% capacity, and doesn’t call a Mac obsolete until 7 years after it stops selling it.

How long do laptops last on average?

No maker publishes an average for the whole laptop. Batteries last 2 to 5 years on Lenovo’s page and 2 to 4 on HP’s; the software end date often decides it.

Is a 7 year old laptop too old?

Often, yes, because of software rather than hardware. A Windows laptop from around 2019 may not meet Windows 11’s TPM 2.0 and processor rules, and for home PCs, Windows 10 security fixes end on October 12, 2027 even with consumer ESU. A Mac that Apple stopped selling more than seven years ago is obsolete, and service providers can’t order parts for it.

Should I limit charging to 80% to make the battery last longer?

It may help, but the precise gains you’ll read on forums, such as 600 versus 1,800 cycles, came with no source. No maker page we read states a figure for it. HP’s page suggests keeping the battery “between 20% and 80%” for longevity, without saying how much longer it lasts.

What to do next

  1. Check your software clock first: Windows version and ESU status, Chromebook Update schedule, or your Mac against Apple’s newest macOS list.
  2. Read the battery cycle count or run a battery report before you decide the laptop is finished.
  3. If it’s only the battery, price a battery replacement before you price a new laptop.
  4. If you’re replacing it, check whether the paid extended warranty is worth it from its terms, and look at refurbished options with a one-year warranty.
  5. If you need the new one to run specific software, try our Will it run? checker.
