RAM upgradation

[Rubel_Ahmed]

I am using Laptop-  "HP Notebook 15-ac010TU" for last three years. My Notebook became very slow in performing normal operation. Now I want to upgrade my Laptop. My current Configuration is as follows: 

Microprocessor:                 1.6 GHz Intel Celeron N3050 with Intel HD Graphics

Microprocessor Cache:     2 MB cache, 2 cores

Memory:                               4 GB DDR3L-1600 SDRAM (1 x 4 GB)

Video Graphics:                   Intel HD Graphics

Display:                                 15.6" diagonal HD BrightView LED-backlit (1366 x 768)

Hard Drive:                           500 GB 5400 rpm SATA

OS:                                          MS windows 10

Now I have 2 questions: 

Questions 1: Is there any extra slot in motherboard so that I can add a new SSD  for better performance? How do i know whether motherboard have extra slot for SSD or not, without opening the laptops' backside?

Questions 2: Is it possible to upgrade RAM? How do i Know maximum supported capacity of RAM?  How much RAM I can add?

-Thanks in advance!

I must let you know that HP does not recommend upgrades or hardware changes as the device is equipped with parts that perform at its optimal performance by design, that said, the upgradeable parts listed by HP articles are purely for your ease, as the decision to upgrade will be at your own discretion.
