In this quick educational video guide I will show you how simple is to upgrade your HP EliteBook 850 G2 15.6 inch or zoll laptop in a few minutes with this guide not only can you upgrade the ram and the SSD drive but also your wireless card, your main laptop battery and CMOS battery. First I removed the laptop battery and after that I replaced the single stick ddr3 pc3l RAM module with 2 8GB PC3L RAM memory modules from Samsung in total there is now 16GB DDR3L memory on this laptop next I found a cheap 500GB SSD and replaced the old Western Digital black disk drive and installed the windows 10 operating system the laptop wasn't used much that is why I didn't clean the fan because there was no dust it was as almost new. The reason I am upgrading this laptop is because of the touchscreen display and backlit keyboard, and also it's in a pretty good shape with a long lasting battery it is really a great laptop to have even now in 2023. Thanks for watching hopefully this video was helpful to you in some way.
