Sorry this is a repost because I got no response. It is a weird situation. About 4 months ago my DV1002nr booted up flashing the num and caps light 3 flashes. I tried the alternate memory slot PC booted fine. Last week same symptoms. I tried the old original slot again without any luck. I purchased a new memory module and tried it in both slots without success. Reading all about the laptop I decided to buy a new motherboard. The first one arrived and I got 2 different flash codes when the memory was in different slots. 3 flashes in one slot and in the other slot I got 2 flashes. I sent the board back and just got another board. Again I am getting the same two different codes. With the memory in the slot closest to the motherboard I get 3 flashes, with the memory in the outer slot I get 2 flashes. I powered down, removed the battery, held the power button for 30 seconds tried to power up without the battery and only the power supply. I tried with one memory module then with two memory modules and I got the same flashing lights. 2 flashes with memory in the outer slot and when placed in teh other slot 3 flashes. I have no idea what to do now.

Not sure what else you can do to troubleshoot, HP does not go in depth about the 3 flash code, but what I do know is bios does test All memory on the motherboard, which could mean the memory in the processor is faulty, no guarantee, but is about all I can suggest.

Thank you for your response. I never thought of it that way but you are correct. It does work with a memory base. I tried two alternate motherboards that the seller said tested good. I tried new memory sticks in both slots. I never thought of the CPU as a "memory" unit as well. I have a new CPU being shipped and will reply again to this thread with the repsonse just for future HP users that ever get different flash codes from different memory slots...
