HP Pavilion DV7t-2000 Mic and Webcam Error

I have an HP Dv7t-2000 laptop that is running Windows 7. Recently, my mic and wecam both stop working whenever my screen is raised up. If I tilt my screen down to below 45 degrees (to where the screen is hardly visible) the mic and webcam work fine. But when I tilt the screen up the rest of the way it no longer works. I have made no changes to my system prior to the error and there are no error messages. I know that the mic and webcam are becoming disconnected though because as I tilt the screen, the sound for a device being unplugged/plugged in will sound off at the respective screen positions.

Can I replace the HDD in my Pavilion Dv7t-2000?

Ok so I bought my laptop a little over a year ago with a 320gb HDD. Now I know that's a good bit of space but I've nearly maxed it out a few time so I want to upgrade it. I already have the new hard drive, 750gb and have it set up but I can't for the life of me figure out how to get the old hard drive out. I easily found where it is but I can't figure out how to lift it out. Can I just push the data cable off and then it can rotate up? If asked I can post a picture of it but for now I just want to know if any one has any guesses.

http://h20574.www2.hp.com/results.htm?SID=3884606&MEID=B3F9837B-7043-4761-A36E-A0D4FD1CED63
This is the official HP Services Media Library for your dv7-2000 Intel system.
Select the "Primary hard disk drive ( CSR) " at the left-handed side menu, it should pop up both video and text to guide you to remove the hard drive.
However, I am not sure the Operating System can support the hard drive size upto 750GB or not.
Anyway, good luck.

What is the difference between the HP Pavilion dv7t models NQ339AV and NZ584AV ?

My dv7t 3000 CTO just arrived this morning. The order summary said I was getting a model NZ584AV. The delivery invoice and product says what was delivered is a NQ339AV.
How do I find out the difference between these models?
By the way, it shipped two days early, and even though it didn't leave Shanghai until Tuesday, it still arrived in New Jersey Friday morning. Amazing!!!

I have a HP Pavilion dv 2000 laptop and an HP Photosmart C7280 wireless printer.

I have an HP Pavilllion dv2000 laptop and an HP Photosmart C7280 wireless printer. They have worked well together until I reformatted and added Windows 7 on the laptop. I went online and downloaded the Windows 7 Printer Wizard. It recognizes my printer and says it has been installed. I have followed their directions and plugged USB cable into printer from laptop. It prints that way. How can I get this to print wirelessly?

Mic and cam

this may be a dumb question, but how do I know if there is a built in mic and webcam on my computer. My husbands says it is here like his laptop but I do not see how to turn on the cam or know if the mic is working
I have a new hp pavillion, 24 in monitor,,, I do know my way around a computer but vista is very new to me

If you tell us the exact model number for your PC and Monitor, I can tell you for sure....I'm betting you won't have a mic or cam built into the Desktop PC, but you might in the monitor.

HP Pavilion DV7T‐4100 CTO USB 3

I have a
HP Pavilion
DV7T‐4100 CTO
and it appears that is does not have any usb3 ports.
I just bought a usb3/sata hd caddy.
Now my questions is will the usb 2 ports put out enought "juice" to run the usb 3 caddy which has only one usb connections and no external power supply?
I know that my HP Pavilion DV7T‐4100 CTO has a combo usb2/firewire port and I'm wondering if I pug my usb3 caddy into it will it power up the HD?
I belive that usb3 is downwardly compatable with usb2. So if the connection has enought "juice" will it run the HD?
Thanks
rafalovich

Hi rafalovich,
You are correct, that USB 3.0 is backwards compatible with USB 2.0. There are plenty of USB 2.0 SATA Docks, so it should provide enough power, but the transfer rates would be at 2.0 USB speeds.
Hope this helps.

HP Pavilion dv7t-7000 Under Warranty and Support won't help

Hello,
I have my pavilion laptop suddenly have power outages. Verified that the product is under warranty and submitted a case. The helpful support responded. Closed my case. Then proceeded to tell me that I had to go to another site to submit. The link led me to exactly where they just closed the case and I could see my case I just opened marked as closed. Thanks for the help. In an email, this very helpful support person told me to navigate to chat and their directions didn't lead me to any chat. So I'm left with a product under warranty that HP has cleverly hidden all means of support and actually fulfilling the warranty.
========================================================================================
So throwing out the case notes and hoping anyone within HP or the community can lend guidance.

Problem description: Getting multiple eventid 41 associated with sudden shutdown of computer ("The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."). I initially thought it was disk crash so replaced the hard drives and problem continues. I checked the power supply cord which was facing a recall and that appeared fine (not covered by the recall). Seems this is under warranty and this is freezing me up from doing work.

i have a hp pavilion dv7 notebook pc and i'm get and error message that my integrated camara is off, and when I go into skype or cyberlink i can not see me

Hey Sam55555,
I see that you're having an issue with the webcam.
Could you provide me with a model and product number of your notebook.
So that I may look into this further to try and provide you with more helpful instructions.
Also, this Document should help you out. If it doesn't let me know the full model name and i will find a document for your notebook.
What i consider doing is the section that says "Reinstalling the original webcam program that came with your computer".

New Hard Disc Drive for HP Pavilion dv6 because of 303 and 305 error messages

Hello
My laptop was getting slower and slower so I did a default restore via the recovery partition and when it rebooted to start the reformat and reinstall to factory condition I got a message on the screen telling me to run the hard disc drive test. Did this and got the 303 and 305 error messages. The restore to default setting worked however after doing research in the error codes I realise I'm up for a new hard disc drive.
My laptop is a HP Pavilion dvd6-3203TU with WIndows 7 Home Premium installed. It currently has a 320GB TOSHIBA MK3265GSXX hard disc drive in it.
After reading through the forums I'm happy to find that my Recovery Discs will reinstall everything to a new hard drive and partition it into a C: drive and also the recovery partition. The main question I have is does my new hard drive have to be 320GB in size like the original or can I buy something like a 500GB+ drive for the laptop. If I have to replace the hard drive I may as will increase the size while at it, if possible that is.
Also does it have to be a Toshiba or can I buy a different brand?
Looking forward to some help in regards to this so thank you in advance also
This question was solved.

Hi,
Your notebook is listed as coming with a 320Gb Hard Drive, but you can just as easily install a 500Gb or 750Gb HDD if you want more space - the drives on the following links are examples that would be fine for your notebook - you're in no way restricted to a particular manufacturer.
500Gb Hard Drive
750Gb Hard Drive.
The procedure to replace the Hard Drive starts on Page 65 of your Maintenance & Service Guide.

HP Pavilion Laptop: Unable to open files, error message and "Recovery" drive appeared

My fairly new HP Pavilion AR5B1425 laptop suddenly displays a big red x and an error message "documents.library-ms (or whatever file I'm trying to access) is no longer working" and is displaying a "recovery" drive listed as "D." My kids were using my computer, and hubby thinks they inadvertently reset my hard drive or something. Any ideas?

Hey reedmiarecki,
Welcome to the HP Support Forums!
With the error message that you are getting, your only option would be to do a factory reset of your computer. If you do need assistance on how to complete a factory reset of your computer, please provide me with the full model number. This will allow me to provide you with specific steps. If you need assistance in finding the model number, please take a look at the following document Guide to finding your product number.
Good Luck!

Pavilion dv7t-4100 CTO Select Edition Entertainment Notebook PC hard disk failure imminent.

Lately this laptop has been running slow and hot. Just yesterday, I recieved an error message on my laptop (HP Pavilion dv7t-4100 CTO), saying "SMART Hard Disk Error" followed by a message telling me that the SMART hard disk check has detected an imminent failure. It told me to backup my files and then press F2 and run a hard disk test. The Quick Test Passed. The complete test gave this error.:"Hard Disk reporting failure 301 Disk Name: Toshiba MK7559GSXP Volume C:/D:/F:/)". I am sure I will have to replace the hard disk. Right now it is a Toshiba 750GB SATA hard disk drive, 5400 RPM, 2.5 inch small form factor (SFF). Can this hard drive be replaced with a Hybrid SSHD like the following:
Seagate Hybrid Drives ST1000LM014 1TB MLC/8GB 64MB Cache SATA 6.0Gb/s NCQ 2.5" Laptop SSHD
or
TOSHIBA Hybrid Drives MQ01ABD100H 1TB+8GB(NAND Flash) 32MB Cache SATA 6.0Gb/s 2.5" Laptop SSHD
If not, what would be the best replacement hard drive that you reccommend?

Hi,
You can put the second HDD on the second bay, existing BIOS can handle this BUT you need more hardware namely a caddy set (caddy & cables). You can buy from:

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 had hard drive issues from within warranty period. i.e. I purchase in 2010 and had a hard drive replaced in 2011 and again in 2012. Next time it failed in 2013 (almost 11 months apart on an average).
Last time when it failed, the warranty had expired so I thought of giving it a few try e.g. running thru bad sector fixing/writing-off softwares from seagate, Toshiba....this got me out of Smart Drive Error.
I have been using the HDD for sometime now but want to be prepared for the next round and I'm sure it'll be gone for good the next time.
Current HDD is 640GB, 7200 RPM Hardrive (replaced in 2012). HP Part# 621046-001.
When replacing, can I use ANY 640GB hard drive? Can I use a hard drive that is larger than 640 GB? Different RPM?
Any suggestions about hard drive?
The recovery discs I had received with the replacement drive did not work correctly. I had to use the first set I had created right after I purchased the laptop.
Thank you.

Hi Pratik Patel
According to product manual:
Your system supports SATA 9.5mm or 12.5mm , 2.5" HDDs
supports upto 2 hard drives
supports SSD too.
Single hard drive configurations supported:
250GB, 320GB, 500GB @7200RPM @9.5mm
640GB @5400RPM @9.5mm
750GB, 1TB @5400RPM @12.5mm
160GB SSD
If you want dual hard drive configurations, please click following link (user manual):
http://h10032.www1.hp.com/ctg/Manual/c02666747.pdf
But, there is not hard fast rules that only 5400rpm can be used instead of 7200rpm, which was used to replace your earlier hdd.
hope this has helped you.
thanks
