[Gsshshjshsehehe]

Can some one let me know these things of this laptop model - HP ENVY x360 - 15t-dr100 CTO ( #8DX23AV_1) 

I) Is the ram on this model is onboard and soldered to the motherboard? 

II) Is the ram upgradable on this model? 

III) Is the SSD upgradeable on this model?

IV) What is the pwm (pulsewidth modulation)  frequency of this model laptop? 

V) Battery life of this model for basic tasks like web browsing, documentation work etc..

@Gsshshjshsehehe here's all you need to know, and I hope I can answer all your queries, if I do & you wish to thank me for my efforts, you could click on "Accept as solution" on my post as the solution should help others too.

i) RAM is not soldered.

ii) Yes, it is! In fact the universal part number of upgradeable parts and the steps to replace are mentioned on page. 33 of Component replacement procedures

iii) SSD is upgradeable as well, steps to replace is mentioned on page.31 of Component replacement procedures in the above link.

iv) Screen flickering / PWM detected - 201.6 Hz ≤99 % brightness setting.

v) The 4-cell, 55.67-Wh, 3.6-Ah, Li-Ion battery battery allows for average runtimes. In our Battery Eater Classic test, the laptop shuts down after 2 hour 30 minutes approx. In the more realistic WLAN v1.3 test (where the notebook is set under the energy saving profile, the screen is set to 150 cd/m2, and a script opens a new web page every 30 seconds)

P.S: Welcome to HP Community 😉

I hope that answers your query,

Have a great day ahead.
