1, I suggest you contact your local HP service center to see if there are any upgrade accessories suitable for your model.

For the contact information of the Gold Medal Service Center, you can choose your province and city and the product type you use through the following websites:

/zh/support-drivers/e support/as CPPS . html

If you use non-HP official accessories, it is recommended to conduct on-site testing and confirm the warranty of replacement hardware with the dealer in advance.

2. The cpu, graphics card and motherboard of notebook products are highly integrated and customized products. Replacing any component alone may lead to hardware compatibility problems, and the upgrade flexibility of these components will be very low, not only CPU and graphics card, but also wireless network card.

3. To improve the performance of the notebook, you can consider upgrading the memory and hard disk capacity. Upgrading these two parts has high security and compatibility. Because these two parts are the upgradeable parts we ordered.

As for the hard disk, HP tested the following hard disk capacity with the parameter of 9.5mm ATA- 100.

30GB at 4200 rpm

40GB at 4200 rpm

60GB at 4200 rpm

40GB，5400 rpm

60GB at 5400 rpm

Memory aspect

According to the query, the notebook can support up to 2 GB of memory, with 2 memory slots, and a single notebook can support up to 1GB. It is recommended to buy PC2700 SDRAM 2GB DDR333 for memory, but there may be no accessories in this field on the market. Please contact the dealer or service center for details.

I hope the above reply can help you.
