Do you have any idea how to replace the RAM, which according to the information I've read is soldered in? Which 32GB RAM with which clock speed would be compatible and which company can you get it from?
Can a faster network card with WIFI 6 to 7 be retrofitted?

[@rickstechrepairs]

if its soldered you cant replace
you should be able to replace the wifi

[@ekeretteekpo3004]

In your experience can the battery be upgraded to something more than 45Wh that it commonly comes with?

[@rickstechrepairs]

not sure sorry

[@BlackB00ST]

Bro how do I fix the gray screen and start up failure

[@rickstechrepairs]

not sure

[@ekeretteekpo3004]

What type of fluid did you use to wipe the paste off of the processor?

[@rickstechrepairs]

Isopropyl alcohol

[@ekeretteekpo3004]

@@rickstechrepairs thank you. I'll see if I can source the thermal paste locally because it seems sort of outrageous getting it at some prices I am finding it on Aliexpress unless I would be buying other things alongside. The shipping fee costs more than the item. 😁 😂

[@arkanullahsaad4639]

[@rickstechrepairs]

didnt monitor it
