Introduction |
| If you own one of these laptops, you will know these things about it regarding the performance and the battery. | | If you own one of these laptops, these laptops do not perform well with the 6 cell battery. Use this guide to replace a worn out battery or install a more appropriate battery. | | '''Note: If you have a slice battery installed, you will need to remove this before the primary battery can be removed.''' | | | * It's a powerhouse laptop for the money you spend on it(and it's even better if you get it refurbished) | | * If you get one used or refurbished/scratch and dent and it comes with the 6 cell battery, you will find out shortly after owning the laptop this battery is too weak. You really need a 9 cell battery to get any acceptable battery time or the off the charger time isn't that great; about 3:15 once it's in the 9% wear range.This becomes even more evident if yours has the i7-4800MQ/Dual Video configuration and if you use the dedicated GPU, since this only makes the problem worse then it would be on the Intel graphics by cutting it by about a hour from 3:15 to 2:15. | | | In this guide, I will show you how to replace the battery, and find your Windows COA if you ever need it to reinstall Windows on this laptop computer if you have Windows 7 on this. Windows 8 has the key in the BIOS, and the COA you will find is a tamper evident Windows 8.1 Pro sticker. '''No, just because the key is in the BIOS for these machines DOES NOT make installing Windows 8.1 Pro legal! It will work, but without that sticker it's unlicensed and illegal.''' | | | After you read this, you should know how to replace the battery and find your Windows 7 COA on this laptop. You should know Dell also sells a slice battery you can put into the E-Port on this notebook but I am not covering installation of this. This only covers the main battery pack you need to run the laptop on battery. | | This guide will show you how to remove the battery and locate the system COA, if your machine has Windows 7. You will need this to reload Windows unless you have Dell SLIC media. | | Windows 8.1 Pro stores the key in the BIOS, so you will only find a Windows 8.1 sticker on the bottom of the computer. You do not need the COA or Dell media with Windows 8.1 Pro. |
