How can I change my ram of HP 15-bs075TX model laptop?

Hi @matiz

According to the service manual for your laptop taken from this webpage the memory options are dependant on the configuration of the laptop and are outlined on p.2-3 of the manual.

If applicable to your laptop configuration, scroll to p.50 to view the necessary pre-requisite steps and then the procedure to remove the memory module.

The part numbers for the modules are also listed on p.50 If you search online using the appropriate part number only, in the search box of your browser, you’ll get results for suppliers of the part.

Hopefully this is of some help.
