Pavilion DV7T - 1200 CTO happened w / Wireless issues - work in progress - solved

I took delivery on a DV7T yesterday. It is configured with the minimap Intel 5100 AGN & Vista 32 Home premium (my first Vista machine). I had updated my wireless router home in anticipation of his arrival, installation of a model of D - Link DIR-655 (Vista friendly 802.11n capable). The router plays well with my existing XP laptop and has been configured for WPA2 AES & compatibility b/g/n.

I configured the appropriate connection parameters and launched a manual connection. I made changes to the router so the SSID was visible and defined the DV7T for automatic connection, but it took often more a minute before the DV7T would see even the network wireless and even a minute or two before reporting the signal strength. Each time, connection attempts failed, reports of a lack of response from the router. After the double check (and returning) settings and password several times (and the audit by doing the same thing on another laptop which connected very well) I finally decided there was a problem and called for help. Given that the order had been placed through Costco, I went through their Concierge as a first level service. Their script for was power off all computers (XP) on the network saying that a common problem was having a Vista machine join a network with XP already connected machines. No joy. Same lack of goodness after removing/reinstalling the drivers. It was as much as the script went to attempts at original resolution.

At this point, no resolution & I plan just to return the machine for a refund (lack of wireless really it would damage the intended use). Propelled upwards all the equipment I had turned off. Bored of not knowing for sure if it was an inherent incompatibility or a hardware problem (the day of delivery!) I ended up out and pick up an express format card card N Wireless of Linksys. Responsible drivers, plugged in the card and voila! immediately, the machine connects using the configuration of the connection that I had entered previously. On top of that, the flow of data showed that 240-270 mbits.

With this info, I went back to service, initially to the connection of Costco and then discussed in HP support. After a 3 hour marathon call, HP sends a replacement 5100AGN card to 'see if this fixes things', if it is not, the machine must go back to the service (as a problem of antennas would not be repairable client). Part of the duration of a call has been associated with finding the right part for a machine CTO. The wireless card on my machine something SN (Broadcom) was set apart from the 5100 (although the list mentioned packing a minimap Intel next gen and the Manager device reports an Intel 5100AGN). They have finally found a suitable part number (I hope).

I just thought I would pass this along in case where someone else found themselves in a similar situation. I'll post much after that the replacement property is displayed. As a side note, the Linksys N Ultra Rangeplus expresscard works really well as a replacement. Of course I'd rather not have something projecting from the side, but it certainly did the job.

EDITION - ADDENDUM

After the above post, I couldn't help but think that a problem of antennas sounded very probably - maybe a lead broken/disconnected (something I mentioned to the technology of the telephone service). In any case, just a minute before, I went ahead and pulled the bottom panel, so I could take a look at the wireless card. Technology said there would be two tracks running to the card - only was connected, the other has fallen in a crack between the card and the frame. The wire not connected has been labeled "main" and there is a connector on the "main" labelled map The two sons had been celo-glued to the card (in the broad sense), but I had the disconnected an oriented properly & pressed into the connector on the card. He buttoned & turned on the machine. He immediately finds the wireless network and connection has been made in a few seconds.

My only ongoing question may turn out to be wireless performance. Connection with the linksys card speeds were always above 200 (230-270). Speeds, I see on the bed in so far have been initially lower than 100, with the best after being 150 mbits. Any suggestions for how this can be improved? Will the adapter 'learn' alone and get better over time?

FINAL ADDENDUM-

Model found on another forum that the 5100AGN has apparently a maximum 150 Mbps on a 300 Mbps max for RX & TX... the 5300AGN is 300 in both directions.

This suggests that the 150 that I see is as good as it gets for my integrated card. Apparently, the Linksys expresscard I used is good for TX/RX 300.

I don't know that the costco guys worked just for the trouble shooting script, he gave. On the plus side, he had an understanding of the issues, & spoke vernacular American English (and not in a call center offshore). He was ready to continue, but I needed a time out. The second call (after me obtain Linksys for comparison) was good enough and the technology was very ready he climbs to a technician of HP (once again, the continent - not off shore), which was certainly ready to order a replacement part, but crossed a few last checks more that the internal card could not be implemented. The part was sentenced & will be shipped without requiring a deposit of me. The only negative for telephone exchanges, it's neither opening proposed leads the lower panel to check the antennas have been connected correctly.

As stated in the original post - edited-, the final fix was to open the Panel & visually notice that a 'primary' marked lead was not connected to the wireless card. Attaching which lead to the consequence named connector on the Board eliminated the problem. The disparity of the connection speeds between the internal 5100AGN and the Linksys 802.11n expresscard was due to the limitations of card design (150TX/300RX 5100AGN and 300 TX/RX for the Linksys), so the 150 Mbps I see currently for internally is as good it will become. I'll probably send the rear replacement not opened as opposed to actually Exchange cards. (I don't think that the shipment may be shortstopped at this point...).

2nd hard drive for HP Pavilion dv7t-4000 CTO Notebook - what do I need?

Hi, I have the HP Pavilion dv7t-4000 CTO Select Edition Entertainment Notebook (product # WV703AV). It can accommodate two hard disks but only came with one. What would need to be able to install the second hard drive? I need just a connecting cable or I also need to caddy or kit?

Also, would I get a solid state? My laptop that would support or should I just use regular?

Currently, I am on Windows 7 64-bit. I have a 500 GB hd (which came to be partitioned with hp tools/restoration).

Help with what I would need to a conventional hard drive or ssd would be greatly appreciated. I tried to look through messages of others first, but could not find anything specific to my model. Thanks for your time!

Hello:

The only place I know where you can get a 2nd hard drive kit is that provider.

http://www.newmodeus.com/shop/index.php?Main_Page=product_info&products_id=345

Your laptop should be able to work with an SSD, but I can't guarantee it.

I don't really see any point in adding an SSD unless you make the main hard drive, and to do this, you must get an SSD of the same size as the original 500 GB hard drive to use the recovery discs to reinstall the operating system.

Most people get smaller SSD and they use the W7 product key to activate a simple installation of W7.

If you can read all 25 characters of your product key for windows 7, you can do your own installation media and allows to install Windows on a smaller than 500 GB SSD.

If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

Or use the installation of Windows 7 USB/DVD tool to compile the ISO file that you download from Digital River. The link below. You need a 4 GB flash drive to use the USB compilation method.

http://download.CNET.com/Windows-7-USB-DVD-download-tool/3000-18513_4-10972600.html

Use 25 characters on the PC product key to activate the installation.

The key will activate a 32 or 64 bit installation.

Then go to the support of the PC and driver page to install the drivers you need.

Link to downloads ISO of W7 is below.

Pavilion dv7t-6100-cto-quad: I can't get the new drivers on the hp support site

I have restored my ssd from disks that I made the computer when I bought it and I did everything I know to do and can not get the hp support site to give me a list of drivers for that computer. I know there must be some updated drivers for the computer 3 years, but I don't know how to get them and it is interfiering with other programs or drivers that need updated drivers that I can't. Please help me with this. I learned that the site is in place and current, but it does not work as far as I can tell, for my portable quad, dv7t-6100 cto. Everything continues to run and never becomes pilots. Thanks for any help in getting this resolved.

HP Pavilion dv7t-7000 CTO Entertainment Notebook PC - Upgrade processor

Hello

Any help would be appreciated.

I have a HP Pavilion dv7t-7000 CTO Entertainment Notebook PC. Due to a new job, I need to update my processor of the current 2.30 GHz (see exact specifications below, please) of at least 3.0 GHz.

Is there a processor 3.0 GHz there that is compatible with this particular computer? I called tech support and they told me they don't know. I don't know who else to ask.

This computer was purchased just a few months ago (before I got the new job). I really don't buy a new computer, if possible, if I can upgrade the processor in it.

Here are the current processor specifications:

Intel Core i7 3610QM
Codename Ivy Bridge
RPGA Socket 988 B package
The 22nm technology
Specification Intel Core i7-3610QM CPU @ 2.30 GHz

Thanks in advance.

Well, it seems that one (that I found) 3.0 GHz processor that Intel made for my chipset (HM77 Express Chipset) and it's the Extreme edition i7-3940XM (http://ark.intel.com/products/71096/)

Priced at $1,000 +, it looks like I'll be shopping for a new computer.

Don't know if anyone from HP read the peer forums, however, I won't buy another HP product.

This machine had problems outside of me needing to upgrade the processor for my own personal reasons. Your support is grossly lack in all areas even pull your techscannot model with the serial number.

Visitors should not go out on the Internet for questions of research like this.

Pavilion dv6t 1200 CTO for Ghost boot disk

Ahoy, all

I am trying to create a boot disk for purposes of Ghosting. I have the BartPE disk that works with the HP Elitebook 6930p. However, this does not work with Pavilion dv6t 1200 CTO. I think it's because I can't change IDE to AHCI in the BIOS (do not see the option).

And so I think that the problem lies with the drivers of storage but not sure. When I go to Pavilion dv6t 1200 CTO drivers HP website drivers 'Storage' alone I see relate to the USB and a Ricoh card reader.

Any help would be greatly appreciated.

Thank you very much.

figured it out. necessary to get the Intel Matrix drivers out of the Intel site. I also had to get the drivers Realtek NIC Realtek off-site. those in integrated BartPE. works now.

HP Pavilion dv7t-4100 CTO Entertainment Notebook PC Hard Drive replacement

Hello

I have HP Pavilion dv7t-4100 CTO Entertainment Notebook PC, and I had problems with hard disk of the guarantee period. for example I buy in 2010 and had a hard drive replaced in 2011 and 2012. Next time, he failed in 2013 (almost 11 months apart on average).

The last time it failed, the warranty has expired so I thought to give it a try as employment through fixing/amortization of bad sector seagate software, Toshiba... that came out of Smart Drive Error.

I use the HARD drive for some time now, but want to be ready for the next round and I don't know that he's going to be gone for good next time.

Current HARD disk is 640 GB, 7200 RPM hard drive (replaced in 2012). HP 621046-001 manufacturer.

When replacing, can I use ANY hard drive 640 GB? Can I use a hard drive that is higher than 640 GB? Different RPM?

Any suggestions on hard drive?

The recovery discs I had received with the replacement drive did not work properly. I had to use the first game I had created just after I bought the laptop.

Thank you.

Both modules can be used. DDR3L means that memory using low voltage. Means that the modules produce less heat and last longer than DDR3 pure ones. I always use 1600 MHz CL9 DDR3 Corsair pure modules.

Hi there @LeoOfMars

Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff. I understand that you are looking to find out if a video card is compatible with your information system. I'm happy to help you with that.

The main reasons to be sure of are normally feeding you, special (to THE) cable power supply for the graphics card, on the motherboard compatible expansion slot, the drivers for your operating system, another thing to know is the physical size of the map, for moments of cases.

Looking at the specs of your system and the motherboard by default, I listed the type of slot of power and expansion.

HP Pavilion Elite e9180t Desktop PC product specifications and configurable Options

Output power of power: 460 Watt

HP and Compaq desktop PC - specifications of the motherboard, IPMTB-TK (Truckee)

Two graphics PCI Express 2.0 x 16 (for graphics cards)

Go to the video card you are looking at:

GTX 780 3072 MB GDDR5 PCI-E 3.0 OC Custom cooled graphics card

Input power: 1 x 8-pin auxiliary input aux input 1 x 6-pin
Bus type: PCI-Express 3.0 16 x

System requirements:
Mother compatible PCI Express with a slot of chart double-width x 16
Power 600W minimum (with a minimum of 12V current rating of 42A) 3
300 MB of available disk space
2 GB of memory system (4 GB or more recommended)
Microsoft Windows 8, Windows 7, Windows Vista, or Windows XP Operating System (32 or 64-bit)
DVD-ROM drive or Internet connection for installation
DVI, HDMI, DisplayPort or VGA compatible monitor

So on a quick inspection of both devices there are three problems, so this card will not work on your motherboard or with the current power.

I hope this helps.

Bluetooth problem: HP Pavilion dv7t-6100 CTO Quad Edition Entertainment Notebook PC

Hello forums HP!

I have problems with the bluetooth in my HP dv7t-6100.

I am no longer able to see/add devices bluetooth with Windows 7 is to add a device. He was working a few weeks ago, but was (waking up from his sleep would cause the device to turn off and I should enable in Device Manager to operate).

I tried unistalling, then reinstall the drivers Wifi and different bluetooth drivers, but I can't see my bluetooth devices (which I know work btw).

Try to add the com ports manually does not work, and I can't remove them later, because I get the message error "the specified service does not exist.

And by clicking on "Choose a COM port for a Bluetooth device" brings up the help page for Spider Solitaire, which makes no sense.

Any suggestions?

Thank you!

WELL, I GOT MY BLUETOOTH WORKS AGAINN! (Sorry for the caps)

After turning around uninstalling and installing drivers for many hours, deletion of registry keys, reseating the bluetooth module, I finally found something that worked.

I have installed the Toshiba bluetooth stack software and unfortunately, my bluetooth has started working again! Wohoo!

It was difficult to settle at first it seemed that the installation froze on the driver real bluetooth, but just cancel and start the program caused to function normally. (I think its because my stack of drivers/bt bt were corrupt and I couldn't make them disappear completely).

So, if your bluetooth stops working to the point where mine was to, try another bluetooth stack. It should not be Toshiba, but it happens to work with my HP laptop.

SEE YOU SOON!

dv7t-1200 CTO portable audio device no longer works

A few days ago I had a problem where my volume control would pop up on my screen (in itself) and try to scroll through the continuous volume control. It was obviously very annoying, I went on HP solutions and has seen an Audio driver updated and installed. Now the boring "on the screen" scrollbar volume ceased to appear, but now I have no sound at all. When I right click the icon in the taskbar to open the volume mixer he said now any installed device. When I go to Device Manager in my control panel, everything about her says "the device is functioning properly. I noticed after I had downloaded the audio update there was the text of presentation you need to update the update of the BIOS before updating the audio update - too late, but I downloaded the BIOS update last night. Still no sound. I am running Vista Ultimate 64 bit and the downloads are for this. Someone at - it ideas? It would be much appreciated.

Hello

It may be worth trying. Stop the laptop, remove the AC adapter and remove the battery. Now, press and hold the power button on the laptop for a good 30 seconds. Reinsert the battery, connect the power adapter and start Notepad.

Now, Windows Control Panel, open Device Manager, open sound, video and game controllers, right click on your audio device annd, select Properties. Click the driver tab, and then click on "Roll Back Driver". Once done, restart the computer and see if that helped the issue with your audio files.

Best wishes
