Introduction |
| If you own one of these laptops, you will know these things about it regarding the performance and the battery. | | | * 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, technically.''' | | 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. You may need to look around for the slice battery due to new TSA battery restrictions and Dell responding by burying the battery, but you will find it as it was once advertised on the battery page for this laptop. if I find a link to the battery, I will post it in the guide. '''However, if I think they buriedpost it so people don't get as madblame me if the TSA confiscates these batteries for some ridiculous reason, even thoughit if you misread the battery restriction only really affects rules!'''
spare batteries''' you travel with, but consideringHere's the [http://safetravel.dot.gov/definitions.html#larger_lithium_ion|page from the TSA] I can get away with as much as they dofind on this until I can find a way to explain this in language that's iFixit friendly. [http://safetravel.dot.gov/larger_batt.html|Oh, you never know if they will take it off the laptop and confiscate itthis one.] |
