Question about HP Pavilion ze4540IUS (ZE4540US) PC Notebook

1 Answer

Upgrading RAM I want to upgrade my RAM. When searching the internet sites they tell me that I can use SO-Ram rather than SD-Ram. Is there a difference? And, are they compatible. I currently have 250 and want to upgrade to 1g. The computer has two slots so I will be replacing anything that is in there currently.

  • 64 Answers has a great scanner that will scan your system and tell you what kind of memory is installed and make suggestions as to compatible pieces. I actually buy from there, but even if you don't their scan tool works really well.

Internet connection causes music files to hang music, itunes or cd will not playback without "hanging "while connected to the internet

You may have some memory issues. I would suggest upgrading your RAM. RAM decreases during playback of any type of media. If you are listening to music online, I would suggest upgrading your connection speed from your ISP.

Best advice....go to and run their system scanner. It will tell you what you have, what kind it takes, and the max. amount you can install. They will also suggest upgrades.

Upgrading acer laptop RAM

You Can Actually Upgrade This To 2 Gig Memory.
Each Slot Will Take 1 A Gig Strip.
I,d suggest Buying another 256 mb Strip, To Put Into Slot 2.
Or Buy a 512mb ( Half Gig ) Which Will Give you 750mb With your Existing Strip Already In There. ** Recommend 1 Gigabyte Max** 2 gig of Ram in This Baby Would Probably Start Glowing.
You Can Buy DDR/266/333 In 256/512/1 Gig Strips. These Are Commonly Known As SD-RAM-Modules.

Acer's support isn't the best. IMHO But go to their support site anyway and look up your laptops manual (there should be instructions on upgrading your RAM there). I did find that your machine will accept up to 4GB of RAM 2 X 2GB sticks. There should be a door or port (for easy user RAM upgrading) that is being overlooked, but again it is an Acer.
Good luck.
