Does my Laptop have Discrete or UMA Memory?

Hello there...
After about 14 months the laptop my mother purchased for me for my 2nd year of Grad School has experienced its first major issue as the cooling fan is malfunctioning. At start up before the OS boots it tells me the fan is malfunctioning and therefore it wont boot unless I tell it too.
So I want to purchase a replacement fan so I can take it to the local repair shop and get it fixed. I believe that I've found the two potential options for fans as well. However, according to the manual the part is dependent upon whether the" computer model is equipped with an Intel processor and a graphics subsystem with UMA memory or discrete memory". Unfortunately I have no idea what this means at all...
This is the laptop...

Thank you very much for anybody that can help me.

Fan replacement - do I have discrete or UMA memory?

Hi,
I have an HP Pavilion dv7-6c80us laptop that I need to replace the cooling fan on.
Intel HD Graphics 3000
Intel HM65
Intel core i7 2670QM
To order a replacement fan, I need to know whether I have:
a graphics subsystem with
2048-MB of discrete memory
(Part #666391-001)
a graphics subsystem with
1024-MB of discrete memory
(Part #666390-001)
a graphics subsystem with
UMA memory
(Part #666392-001)
How do I find this information?
Thanks.

If it only has the Intel HD 3000 Graphics, that is UMA.
The specs confirm that is the case:

What fan to get? don't know how to find if I have discrete or UMA graphics subsystems (dv7t-7000)

fan needs replaced, don't know if I have discrete or UMA graphics, options are as follows from the maintenance manual:
For use only with computer models equipped with graphics subsystems with UMA memory 603690-001
For use only with only with computer models equipped with ATI Mobility Radeon HD 5470 graphics subsystems with discrete memory 604787-001
For use only with computer models equipped with ATI Mobility Radeon HD 5650 graphics subsystems with discrete memory 603691-001
I am unsure of which one of these three options I have and don't know how to find out. Device manager lists Intel HD Graphics 4000, and NVIDIA GeForce GT 630M

Why does my MBP have such a huge Memory File Cache?

My avaiable RAM keeps getting very low (<25 MB) and the Memeory File Cache is huge (5-6 GB). I have to run the Memory Cleaner several times just to get avaiable RAM back to 4-6 GB!

Normal in Mavericks. Delete "Memory Cleaner," which is worthless.

Fan/cooling dv7-6162sf : graphic subsystem (discret or uma memory)

I am trying to determine which graphic subsystem i have in my dv7-6162sf laptop, so i can determine which cooling fan i need to order.
Thanks

Hi,
This lappy should have a discrete/dedicated graphics subsystem. The specs say Radeon HD 6490M so it means a dedicated graphics card with its own memory. There should be also an Intel HD 3000 but this graphics chip is a part of the CPU. You need a fan for the discrete graphics memory.

Does X-Fi have built in Flash Memory or internal Hard Driv

I can't find any specs on whether the X-Fi's internal storage is flash memory or if it uses a hard dri've.
I know about the SD card slot and I am not referring to that which of course is flash memory. I mean the 8/6/32 gig storage depending on the model.
Anyone know?

Hi Merkaba777,
The ZEN X-Fi is flash memory based.

Why does my laptop have problems with USB card reader?

I have a PowerBook G4, and I connect a multi-slot card reader to a USB port to read CompactFlash media. I have two problems with it and wonder if anyone can help.
1) When I "eject" the media, then physically remove the media from the card reader, I occasionally get a "Media not removed properly" alert message. I always wait several seconds after the media icon has disappeared from the desktop before removing the media. I can't seem to reproduce this on demand, but it appears to be happening more frequently.
2) Once the media has been removed from the card reader, the computer no longer recognizes it when it is reinserted into the card reader. I have to unplug the card reader from the USB port, then plug it back before the media is recognized.
Any ideas how to resolve these issues?

1) Wait longer. It can sometimes be necessary to wait as long as 15 seconds. I've never seen a good explanation of why.
2) Are you plugging the reader directly into a USB port on the Powerbook? Are any other bus-powered USB devices connected simultaneously? If so, disconnect them and test again. If you have an AC-powered USB hub available (or can borrow one), try plugging that into the computer and the reader into the hub. (Don't use a bus-powered hub.)

It uses system RAM it doesn't have it own system RAM if it does it most likely is to small to see. Discrete memory is only for Video GPU in laptop not for audio.

How to tell if my laptop integrated graphics uses UMA or discrete memory?

Hello,
I'm looking to buy a replacement heatsink/fan assembly for my DV6-6117DX laptop as the ball bearing on my fan is dieing. Using the service manual I've narrowed it down to two parts:
650848-001 (For use only with computer models equipped with an AMD A8, A6, or A4 processor and a graphics subsystem with discrete memory)
650847-001 (For use only with computer models equipped with an AMD A8, A6, or A4 processor and a graphics subsystem with UMA memory)
I'm just not sure whether my laptop's integrated graphics uses discrete memory or UMA memory. The processor is an AMD Quad-Core A8-3500M with integrated AMD Radeon HD 6620G Discrete-Class Graphics. This is copied from the HP specs page. Does the "discrete-class graphics" imply that it uses discrete memory?
Thanks for any help!

In my original post, I've already narrowed it down to one of two parts. My CPU is the AMD A8, my GPU is the AMD 6620G. I just don't know how to tell if my graphics use discrete memory or UMA memory, which will decide between the two heatsink/fan parts.
Put this way if you have AMD video that is the discrete video and you most likely can't upgrade that video if that what your thinking of doing. It should have 1-2gigs of Video RAM that what it usualy comes with but that doesn't qualify it for a Gaming laptop if that is what your looking do to. Gaming laptops cost upwards to 2000US for decent game play and those Video are the higher end video chipset. And if you want to know if you have shared memory with the video look at your UEFI or Bios and look for shared video memory and you will have more insight into the video itself.

DV6-6060sa Do I have discrete graphics memory or UMA graphics memory? + Where is 'System Fan 'B''

Hi There,
I am going to attempt replacing a fan on my Pavilion DV6-6060sa Laptop, I have been looking around on the net and have just now read through the service manual to better understand which component needs replacing.
I am going to be changing system fan 'B', as the error message states at start-up. (I have tried compressed air spray through the air vents but this has not worked.)
In order for me to purchase the correct part number I need to know whether I have Discrete memory or UMA memory.
As stated above I have a Pavilion DV6-6060sa unit, the below snippet is from the service manual.
(12) Fan/heat sink assembly (includes replacement thermal material):
For use only with computer models equipped with ATI Mobility Radeon HD4650
graphics subsystems
518435-001
For use only with computer models equipped with graphics subsystems with discrete
graphics memory
512837-001
For use only with computer models equipped with graphics subsystems with UMA
graphics memory
512830-001
Could you let me know which part number I require, and also send me a link for an original HP replacement part please?
The fan I will be replacing is the fan closes to the power button, looking down at the laptop from a birds eye view it is located on the upper left corner. The two vents (one on the left and one on the top) usud to have air forced out from the fan, which is now not working. I take it this is system fan 'B' and is the heat sink?
Please can you confirm the above information?
Specifically Including a description of which fan system fan 'B' is? (thank you)
I appreciate your help, Simon.

Hi,
90B is the error code, not the location of the fan.

Dm4-1060us laptop SD Card Reader 5-in-1 question. Does it work with SDHC and SDXC memory cards?

dm4-1060us laptop SD Card Reader 5-in-1 question. Does it work with SDHC and SDXC memory cards?

This cart reader is a kind of multi card reader and you can use different cards with it. In my opinion every multi device should be used very, but very gently. I do not know what happened exactly in your case but maybe you have damaged something inside.
Try to restart your notebook and use other SD card to check if everything works well. Please do it very gently and if you see something is wrong stop with inserting the card.
I use 1 GB SD card on my A200 without any problems.
In my opinion you should check notebook by technician.
Bye and good luck!

You appear to have AVG installed:
*See --> http://forums.avg.com/ww-en/avg-forums?sec=thread&act=show&id=173969#post_173969
From reading on the internet, it appears that when there is a spike in memory usage, AVG "interprets" that as a memory leak, possibly caused by malware. AVG could be incorrect concerning that assumption. Maybe they are being a bit too conservative about memory usage; just my opinion.
The decision is yours to turn off the "advisor" or leave it on.
