Cooling Fan is inoperative. Receiving 90b error message.
I plan to order a replacement fan, but need to determine which part number to order. Per the Manual:
- P/N 666527-001 (For use with computer models equipped with an AMD processor and a graphics subsystem with discrete memory)
- P/N 666526-001 (For use with computer models equipped with an AMD processor and a graphics subsystem with UMA memory)
How do I tell if my laptop uses UMA or discrete memory?
The laptop has an ATI Mobility Radeon HD 4530 Series graphics chip. I understand that it has 512 MB of GDDR3 memory on the card.
From this I assume that this system is considered to have discrete memory and therefore I should replace the fan with part number 666527-001.
Please confirm the use of this part number or advise otherwise. Thank you.
