7805u bluetooth install

i installed a bluetooth chip from http://laptopparts.vivotechnology.net/Items/!MSC-HP-513?gclid=CMb0sPqTj5gCFRFWagodTxPT8w last night and took some pics. went really smooth and windows 7 installed all the drivers for me. Not sure how it will work when i have to go back to vista. one thing i love about windows 7 is the fact my cell phone bluetooth headset works on my laptop. Never could get it to work on vista. btw the FN+F8 key works. well anyway pics where to large so i uploaded offsite. http://s465.photobucket.com/albums/rr12/filebug/7805u/

 

Hey man thanks for the pics.. is there any way you can give me some instructions on how to do this? Or where you found your instructions? Thanks man!

 

That is cool, can you make a how to post

 

Yeah I'd love a step by step (even briefly). I'm under the impression you remove battery, remove 2 screws under it, remove media bar, remove keyboard, and then flip it back over and take ALL the screws out and seperate the halves, somewhere in there you have to disconnect the display I think too, but I haven't found a suscinct write up of what comes off in what order, I've done this dozens of times to other notebooks so personally I don't need every little step but an overview would sure be helpful. My module hit the mail a couple days ago, so it should be here soon.

 

Was the included cable compatible?

Last time I bought a BMND2045 adapter, the included 8pin cable was too small so I had to jerry rig it. Worked for about 3 months and then the chip fried from a crossed lead.

If it fits perfectly, I'll be buying one.

 

Step 1 : remove the two small black screws from under the battery( shown in picture)

Step 2: remove media bar: this was the hardest part cause I was really trying not to break anything. What I did was pry’d with my pocket knife under the page up page dn buttons. There are tabs on the front left and right I learned later on in the process. Just be easy but forcefull if you know what I mean. Make sure the screen is all the way open and laying flat with screen pointing toward the sky.This is the only part that really puts you on the verge of breaking something.

Step 3: remove the 3 silver screws and one long black one at the top of the keyboard. There is a wire connected to the keyboard unclip it and the keyboard is removed.

Step 4: remove all the user panels from the bottom to give you access to the wifi card and processor.Remove the antenna from the wireless card. Also remove the harddrives. And the DVD-RW drive. It is held down by one screw under a rubber sticker next to where the harddrive is.

Step 5: unplug the wifi card and the video cable then remove the 4 screws holding the LCD on ( 2 underneath and 2 under the media panel. The video cable is taped to the palm rest so you can just gently pull it up. Make sure you unpluged the wireless antenna’s in step 4 cause when you remove the lcd those come off with it.

Step 6: Remove all the screws from the bottom ( 8 that you can see and one under the harddrive)

Step 7: Can’t remember but I think there are 7 screws on the top of the laptop holding the palmrest down. Pretty much there are 6 along the back and I think only one under where the keypad goes. Double check as I did miss a few when is started pulling it apart

Step 8: I started where the dvd rom drive is and carefully pulled it apart. If you feel it is tough to come up then check again for screws. Really isn’t that good a snaps holding the palmrest down so you shouldn’t have to much resistance. Be extra careful around the back as it is really thin plastic.

There is mounts for the bluetooth board but I didn’t have any screws big enough to fit in those holes so I just stuck it to the foam pad there. It is sticky already. I placed it with the label up on mine. I put it all back togather is reverse order. Was very simple. and fits perfectly. works just like factory and really looks factory minus the missing screws to hold it down. Just remember it shouldn't take that much force to remove any part so just double check for screws before being to forceful. If you need any help let me know and i will do my best. My plan was to make a step by step on total disassembly but got interrupted half way through with work. So i will make one when i get my AS5 in to redo the GPU/CPU thermal paste.

 

I always thought this should be relatively easy. Glad someone finally did it and with good results! Thank you and I hope you enjoy the full functionality of your bluetooth-enabled laptop.

+rep!

 

yeah im loving not having to plug in my logitech bluetooth adapter now one extra usb port is the whole reason i did it

 

Do you remember the length of the cable you got? Did Vivo sent you a short one or long one?

I am looking to see if I can get the cable + chip a little bit cheaper than what Vivo sells.

 

it was a short cable not sure on length.it was just the right length. i was gonna go the ebay route but was told this one would fit and decided it wasn't really worth me messing something up to get it to work so i paid a lil extra

 

What all do I need besides what they include in the link? Do I have to buy an antenna separately? Don't really want to tear the whole board apart if I can avoid it heh

 

Antenna is built in, if you've looked at some of the pictures one side is the chips etc covered in a sticker and the other side is like a foam insulator surrounding what kinda resembles a razor blade with a couple pieces taken out of it, that's the antenna.

 

Nice. So what's this about a wire antenna people were talking about? >_>

 

The cable mentioned in the thread (being long, short etc) is the one that goes from the 8 pin header on the motherboard to the module. That's the only mention of a wire or cable I've seen in relation to bluetooth?

 

That'd be it. So I can't just incorporate the card into the slot on the board, but have to take the thing apart? Not a fun project, that one.

 

No its not a minor project. There are mini PCI-E solutions out there, but they cost as much or more and I think those do require a separate antenna that you'd have to at a minimum stuff in the card area. This is probably the most elegant solution as there is a place for it to go and to plug into and it uses an otherwise unused USB channel, but its definately a lot of work to get to where it is.

 

Make the effort! You'll be much more satisfied with the results.

 

they inclue everything you will need in that link. i only needed the a screwdriver and some time

 

filebug thanks for the pictures and instructions. Made it easy to take apart the 7805u to install the bluetooth adapter. I love having internal blue tooth.

 

I snoozed and lost, no more in stock.................

 

filebug, thank you so much. Same as TANWare, I hesitated and lost....

But there will be another day.....

 

Well, I managed to snag one of these and just finished installing it. Vista 64 doesn't detect it at all! I'm pretty sure the connections are fine, I checked them 3 times. I might try and install Windows 7 to see if it makes a difference but I doubt it. Will probably have to tear it down again to redo the connections.

While I had it torn down I did take the rest of it apart and redid moth the CPU and GPU with MX-2. Also noticed that the GPU heat sink covers the GPU memory in addition to the GPU but there was no thermal compound on them so I put MX-2 on them too - can't hurt.

Temps are much lower CPU cores are 4 degrees cooler then before MX-2 and GPU core is about 6 degrees cooler. That doesn't seem like much but the temps before were measured with ambient of 66 degrees and after with ambient of 71 degrees! Definitely worth the effort. Oh yes the North Bridge on the 7805u has the same gap problem that the 7801u did so do not muck with the Gap filling thermal tape they use for it.

Anyone have any ideas on the bluetooth not working?

 

Did you do the FN+F6 to turn it on? Thats about the only thing I can think of off the bat.

 

Like Big Mike said... you will need to do FN+F6. It is off by default until you do that. Also if the wireless switch is off then it will be off also.

 

Brilliant, that did the trick. Who would have thought it would be so simple! Thanks Big Mike and skwayb.

 

For the record I totally stole that info from another thread about the same thing that I read while researching this, so thanks goes to whoever brought it up in that thread. Glad to hear it works, I'm hoping my cable will be here this week so I can get mine going.

 

so will this work, it looks like just a longer cable.............

It LOOKS like it would work, but you should give them a call just to be certain that the connectors are the same as the other unit. As long as the connectors are the right ones and the board is right then all you have to do is tuck in the extra long wire when you install it.

 

So does this cable work? If it does, I'd like to go ahead and install it in my 7805u.

I can vouch for this one. I purchased mine from Hellowifi through ebay and it works flawlessly. The cable is the perfect length too. Nice and easy upgrade. Hardest part is taking the laptop apart, which isn't even difficult. Just take your time and organize everything as you take it apart. Take a few digital pics for reference to make it easier to put back together afterwards.

Hellowifi is where I got mine too, there's a 7805u write up in their listings that I did and a thread about it here if anyone needs instructions.
