Why and how to extend your machine\u2019s life<\/span><\/h2>\n

When your laptop can no longer hold a charge, it doesn\u2019t mean the whole machine is ready for the bin. In the vast majority of cases \u2014 <\/span>over 90% of models<\/b> \u2014 the power pack can be replaced at home. This procedure is an excellent way to <\/span>extend the lifespan<\/b> of your device.<\/span><\/p>\n

How easy it is to get to the battery depends heavily on how your particular model is engineered. To help you plan ahead, we\u2019ve put together a breakdown of battery access difficulty levels.<\/span><\/p>\n

The four battery access levels<\/span><\/h3>\n
    \n
  • 1. Removable (external) battery pack:<\/b>\n
      \n
    • This is the easiest level. These batteries are designed to be swapped in seconds, <\/span>with no tools at all<\/b>.<\/span><\/li>\n<\/ul>\n<\/li>\n
    • 2. Built-in pack with simple access panel:<\/b>\n
        \n
      • This kind of replacement is considered straightforward. The rear panel is easy to remove because all the fixing screws are <\/span>visible and you don\u2019t need to take out any major components<\/b> first.<\/span><\/li>\n<\/ul>\n<\/li>\n
      • 3. Built-in pack requiring complex chassis disassembly:<\/b>\n
          \n
        • Before you start, it is <\/span>essential to watch a video guide<\/b> so you understand the order of disassembly. Access is classed as \u201ccomplex\u201d when screws are hidden (under feet or pads) or when removing the panel means carefully unclipping the case all around the keyboard.<\/span><\/li>\n
        • Two layouts are common:<\/span>\n
            \n
          • Removing the bottom cover gives <\/span>direct access<\/b> to all internal components, including the battery (often seen on some HP business models).<\/span><\/li>\n
          • The keyboard and touchpad assembly has to be lifted off to reveal the motherboard and the battery from underneath (more common on some Asus laptops).<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n
          • 4. Built-in pack fixed with adhesive:<\/b>\n
              \n
            • This is the trickiest scenario. If the battery pack is not only screwed but also <\/span>glued to the chassis<\/b>, it is <\/span>strongly recommended that you use a repair shop<\/b>. Removing glued packs safely calls for the right tools and great care to avoid piercing cells or damaging nearby circuitry.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

              Essential prep: before opening the case<\/span><\/h2>\n

              Whether your battery is easy or awkward to reach, careful preparation is the key to a successful job.<\/span><\/p>\n

              1. Make sure the part is compatible<\/span><\/h3>\n

              The first and most crucial step is ordering the <\/span>correct battery reference<\/b>.<\/span><\/p>\n

                \n
              • For foolproof identification, search using the <\/span>part number printed on your current battery pack<\/b>.<\/span><\/li>\n
              • If you search by laptop model number, be careful. Some models (especially with internal batteries) may have been fitted with <\/span>different battery versions<\/b> over the years. The product number is the only reliable guarantee of compatibility.<\/span><\/li>\n<\/ul>\n

                2. Prioritise quality and performance<\/span><\/h3>\n

                Choosing a <\/span>reliable power pack<\/b> is fundamental for safety. Buying an original (OEM) part is not your only option. Quality replacement batteries often offer a <\/span>better price<\/b> for equal or even better performance. To choose well:<\/span><\/p>\n

                  \n
                • Check the <\/span>ratings and reviews<\/b> left by other buyers.<\/span><\/li>\n
                • Compare the <\/span>capacity values<\/b> (in $\\text{Wh}$ or $\\text{mAh}$) between offers.<\/span><\/li>\n
                • Check the seller\u2019s <\/span>warranty conditions<\/b>.<\/span><\/li>\n<\/ul>\n

                  High-capacity battery options<\/b><\/h4>\n

                  If you opt for a <\/span>high-capacity battery<\/b> to increase runtime, be aware this can slightly change the physical size of the pack.<\/span><\/p>\n

                    \n
                  • Removable models:<\/b> Extra cells often mean a small bulge that raises the rear of the laptop. As long as the connector fits properly, <\/span>a slightly larger size is normal<\/b>.<\/span><\/li>\n
                  • Internal models:<\/b> Extra capacity is achieved either by higher quality cells or by adding more cells. In the latter case, <\/span>make sure your laptop chassis has enough internal space<\/b> (sometimes, the space for a high-capacity pack is the same bay normally used for a second SSD or an optical drive).<\/span><\/li>\n<\/ul>\n

                    Before you start disassembly, <\/span>watching a video specific to your exact model<\/b> is always the best way to get familiar with the internal layout.<\/span><\/p>\n
