need help replacing graphics card on P150HM

hi :hi2:
sorry if theres a guide thread or somesuch posted already. I tried searching the forums but it would bring back whole bunch of irrelevant threads.

anyway the 6990m in my malibal lotus went bad about a month ago. I managed to procure a 675m through ebay.

now to replace it, Ive been hearing a lot of bad things about malibal and i dont feel very inclined to send it back to them for the procedure.

could i get some instructions from you guys? ive open up and taken out the card before so i think i can handle it if you just tell me what i need to do.

im guessing i would need to buy a new paste. can i use the same heatsinks? do i need to mess with the vbios?
here are the details of the card i bought: NVIDIA 2GB GTX 675M Upgrade VGA Card MXM 3 0B | eBay

Thanks guys,

 

no need to mess with the vbios, ull probably just need modified drivers. u can get those from laptopvideo2go.com, for example.
did u buy it with a heatsink included? if not, i would check and make sure if ur old heatsink fits the new gpu and if its possible to make it fit just by rearranging or adding/subtracting thermal pads in specific spots. u might wanna look into purchasing a heatsink specifically designed for the 675m/580m (identical cards, just different name)

as for the thermal paste, u definitely need to apply new paste every time u remove the heatsink from the gpu core. the necessary steps are easy, especially if u already know how to remove/install the card: remove old thermal paste from core using a dry cloth, followed by application of some rubbing alcohol on the cloth in order to completely remove all traces / with a square gpu core apply a rice-sized dot of paste in the middle / with a rectangular gpu core, either apply three small dots or a thin line along the center of the core / let the pressure of the heatsink evenly spread out the paste for you when installing its screws.

thats pretty much it

cheers

thanks for the response

anybody know for a fact if i need new heatsinks? going from 6990m to 675m

or, could someone tell me how i could find out by myself? what are the parts/contacts I need to look out for?

 

Since jaybee basically covered your bases on the card, I'll just address this:

The built-in vBulletin search function isn't exactly practical. Here is a post regarding on how to search the forums for more accurate results: http://forum.notebookreview.com/site-suggestions-help-announcements/631803-thread-search.html#post8154677

 

u could, of course, always ask the seller ull get ur new card from, he should know, especially if its a professional seller a new heatsink with screws isnt that big of an investment compared to the new gpu, but itll greatly reduce any risk of u bricking it due to improper installation.
generally ud have to look out for the vram chips and voltage regulators, but i basically covered any part that i could reach with my heatsink and thermal pads, just to be on the safe side

With the heatsink you need to simply make sure the heat pads are making propper contact which may require re-organisation or adding in/taking away some.
