This is also why I buy higher-end Dell laptops. In fact I&#x27;d suggest to anyone inclined to see what life they can get out of their hardware, before buying a laptop, see if you can find the service manual online. My current laptop is at least 5 years old now and going strong. Battery life sucks, of course, but that&#x27;s just a constant for the age of the laptop. I&#x27;ve had to replace hard drives (easy), get a total air-flow-blocking dust bunny out of the fan (service manual was quite helpful, that involved near total disassembly unfortunately), and replace the keyboard. While I could theoretically blunder my way through the latter two, it&#x27;s nice to have a manual telling you exactly what to do, so you do only and exactly what you need to do. (Every laptop I&#x27;ve had has been different in terms of what you access from the top and the bottom.)
