Windows 10: I have a Dell latitude e7270 laptop. Its battery isn't functioning well anymore.

So I'm using my AC adapter. Should I remove the battery? There are times that it'll sleep or shut down by itself, I'm afraid that it would harm my hard drive and others. Also, there are times that I’m having problems with it because an error occurs. The errors are “Media test failure, check cable” and “No boot device found. Press any key to reboot the machine”. Fortunately, I fix it using the BIOS sequence. However, I thought maybe there are other problems that I should fix, and that involved my battery or BIOS or idk

Dying laptop

Agreed, they're built like tanks. Though you can get them for less if you get a refurbished one. Dell for example sell a Latitude E7270 in the UK for £659 ($875 at current rates).

Dell Refurbished Dell Latitude 12 7000 Series (E7270)

Though if you are prepared to risk buying used, you can pick up real bargains. I recently bought a higher spec E7270 from CashConverters (16GB, i7, full HD touch screen) for around £320 ($425). Mind you, I had to clean-install Windows 10 myself (easy, as it had the 10 Pro key in its bios).
