I found my 1150 on the side of a street and fixed it for under $25.00. I damaged my 2.66 cpu while replacing the fan/heatsink unit. Can you tell me where I can find a Mobile P-4 to upgrade to. Along with where...I need to know any information that I will need to order it. I LOVE my little baby and can't wait to get her back online. Thank you and Thank you for the above post. Glad to know there's help out there for us "tinkerers".
Amazingly, I ventured onto this post tonight, and saw you're having trouble withe your 1150. Although mine is long gone( I sold it around 6 years ago), I have been playing around " tinkering" again with the most notorious of Dell laptops . The Inspiron 5150 . I can't remember exactly what processor It was on my 1150. Seems like the SL7P. Anyway, E-bay is the place. I believe that that system that had the Celeron, had the 478 socket, with a 400 FSB ( front side bus), speed , but I think that the system will up support a 512 L2 cache with a 533 FSB.
Again, check E- Bay. They are flooded with motherboards and there are processors that can be had as long as it is a mobile P- 4 with the right cache/ FSB speed , it should work.
Let me know if I can be of any further help, and ... Good luck !
Check this e- bay listing # 281738661755 I believe this will work.
