The Wifi on my a new ProBook won't turn on. Device Manager says that the device driver for Wifi won't load and may be missing or corrupted. It says the wireless device is an Intel Dual Band Wireless-AC3160 with Bluetooth combo device. The HP driver support page doesn't have a driver for this wireless device.
Specs: ProBook G1 450Windows 7 Professional 64-bitWireless device: Intel Dual Band Wireless-AC3160 with Bluetooth combo device
Â
This is a new ProBook G1 450 which I am still doing basic setup on; I haven't even added my programs to it. I am setting up the preinstalled OS with the HP preinstalled programs. It does successfully connect to the internet via an ethernet cable, and I downloaded many Win 7 and HP updates that way. But it will not connect via a wireless network. It does not recognize that there are any Wifi signals in the area. My old Thinkpad and my tablet recognize a number of strong Wifs in the area, and connect easily to the one which I am authorized to use. The ProBook says there is no wireless in the area.
The ProBook's Wifi is apparently disabled. The wireless light is on (white), and when I click the appropriate icon, there is a message saying that Bluetooth is enabled, but Wifi is disabled. Â The light is supposed to turn on if either of Wifi or Bluetooth or both are turned on, so it is not a malfunction if it turns on when only one is enabled. But I have not tried Bluetooth yet.
Many other ProBook G1 450's apparently have a Ralink wireless device or certain other devices. Not mine. My ProBook apparently has an Intel Dual Bank Wireless-AC3160 with Bluetooth combo device. That's what Device Manager says. And this device might be excellent or perhaps even a nice improvement. However, unfortunately, Device Manager also says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)."
The HP support page for driver downloads for my ProBook does not have any driver for such an Intel wireless device. I didn't try the wireless until having installed many Win and HP updates. At the same time that I have noticed the wifi problem, I found that one HP update won't install: that was for Hotkey Support 5. Since then, I am having a little trouble with a couple of other updates. I mention this in case it is of some interest, but I don't see any connection between these updates and Wifi.

I am having problems with finding drivers for this notebook. When I search for it on this site, nothing shows up and when I find it here it just says "The product you selected, HP ProBook 4330s Notebook PC, is not supported in ...". I just reinstalled the system and don't have the drivers anywhere. I tried using the 4331s drivers, but it just resulted in blue screen of death..

I had to re-install Windows after a hacker locked my system. I hadn't had the unit long, so didn't lose tons of  important data or files. But, I hadn't had time to really get to know my system either....so now I have the new issue of trying to determine what all the hardware is that is not recognized.  I thought I would come to hp.com, find my drivers, download and be DONE.

I have yellow exclamation marks on the following devices in Device Manager:
Â
1. Â Base System Device
2. Â Base System Device
3. Â Ethernet Controller
4> Network Controller
5. Â PCI Simple Com Device
6. Â USB Controller
7. Â Unknown Device
Â
If there weren't SO MANY drivers, this could be simple! Â

Can't seem to find any users of the Probook 4720s yet, it got a nice review over at: HP ProBook 4720s Review - A Review of the HP ProBook 4720s - the viewing angles looks amazing from those pics, but I wonder if it's a trick?

I recently ordered a dm3t with pretty much all the upgrades during one of the sales.
Pretty much the same day I did that, the probook 4320s showed up on their website.
I'm trying to decide if I should return the dm3t and order one of the probooks. Right now the probook doesn't offer the discreet 512mb graphics card or 64 bit OS as choice but the customer support people say it will become available soon.
Basically I just dont know if it's worth the extra money for things like a better cpu, gpu, DVD, and fingerprint scanner.

I intend to use it primarily for some fairly intensive gaming (Fallout 3, etc), media (music, movies), and general work stuff (web surfing, word processing, etc)
I have had an IBM for the last four years and it has served me quite well. My experience with IBM tech support was always good, and the one time I had to get it fixed it was returned promptly, no questions asked.
However there is an HP ProBook that looks quite appealing.
It costs $1865
It ships with Windows XP (important to me)
It has a 2.53 GHz Core 2 Duo Processor
It has a 512 MB ATI video card
3GB of DDR2 Ram
It has a 320 GB 5400rpm HD
It has a 17.3" widescreen 1600x900 display
And here's the kicker: a Blu-Ray drive
The Lenovo is a Thinkpad W500. It is generally quite similar in specs, and a bit cheaper, but it has a 15.4 inch screen (albiet a higher resolution one) and lacks the Blu-Ray drive..............

Comparing the specs, it looks like the probook 4420s is great value compared to the elitebook 8440w. the latter costs 70% more !
If the build quality of the probook is anywhere close to the elitebook, I am puzzled as to why there isnt more attention on the probook.... Just Too NEW?

I've got an issue with the card reader on my hp.
It just won't hold the SD cards in place.
If i hold it with my finger it reads the card, but it won't fixate in there.
If i release the finger the card comes out. On my m1730 i put the card inside, it locks in, i press it, it goes out. So i assume it's a problem with the reader.

In the hp.com configuration options for the ProBook 4710s, they show 3 options:
1. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) without camera
2. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) with camera (must select NQ004AV)
3. 17.3-inch diagonal LED-backlit HD+6 (1600 x 900) BrightView with camera (must select NQ004AV)
I thought LED-backlit was good enough, but option #3 is LED-backlit BRIGHTVIEW... Is this a brighter, "better" screen than option #1 or #2? I'm afraid of ordering this and getting another lemon of a "Brightview" screen like my dv7t screen.
What's "HD+6" ... what does "plus six" do for me ?
I don't see an "NQ004AV" option on the order page, either...
HP is just terrible at explaining these things.
Regarding the keyboard ... it's hard to tell from the pictures at Engadget whether this new chiclet keyboard is backlit or not ... HP doesn't say it is backlit, would be awesome if it was.

what of an extensive issue on a dv2710us on Vista.
One of the crippling elements of this whole situation is this computers CD drive is not working. Windows was not recognizing a CD/DVD drive present, which is what I was trying to fix. So I accessed the recovery manager by pressing F11 on bootup to have Windows install all of the original files, but not format the C drive. Well it began formatting the C drive, and a progress bar showed up so I powered down the PC before it got past 0%. When I powered it back up, I get a "Bootmgr is missing" message and am unable to get past that.
After doing some research online, I accessed the recovery manager and opened Command, and did a Bootrec /fixboot, the operation completed and upon restarting, it booted straight to the recovery manager. I was no longer able to boot to the C drive. I did a little more research and opened up Command again, and used DISKPART to make the C drive active.
This time after rebooting the cmoputer, I am once again given the Bootmgr is missing message. Not only that, I am unable to press f11 to get to recovery manager anymore.
At this point, I mainly need to access the harddrive so I can backup some improtant files, and then do a full reformat of the C drive. I have a disc of Ubuntu I had the idea of loading up to access the C drive, however since the DVD drive is not recognizing discs I am unable to use it. I also downloaded a Vista recovery disc from here and placed it a USB stick drive. Upon booting up I can press f9 to select multi boot options. When the drive is inserted the options are Laptop harddrive, and USB diskette. The USB diskette option is not present when I have the stick drive removed. I select to boot from USB diskette and the computer proceeds with a black screen as if it may boot, but then returns to the initial boot up screen (where you can use F keys to access BIOS, etc.) and then got to Bootmgr is missing.

A friend just showed me his new Dell Vostro lappy. He has 4 GB of DDR2 800mhz memory on it when compared to my 4 GB of DDR2 667mhz memory on my XPS 1530
However, under his windows experience score - he gets 5.9 score for memory operations while I just get a 5.1. I can't believe that a couple of hundred mhz can result in such a drastic difference.
Is there something optimized for his system but not for mine?
