Problems With Tekkit Classic

[AmazingBlox]

You see, I'm new with this Technic Luncher, I helped make aserver in Tekkit, after that, we sort of changed to Tekkit Classic, The problem is, I can enter Tekkit Classic using my computer, But when I enter using the laptop, its just plain white.. waited for around 3-5 mins.. Still nothing.. is this a bug or something? I really need help.. I can't always use the computer, Dad's using it.. :/

Need help ASAP..

When it launches it goes to the screen before the mojang logo and then just stays plain white
