HP/Compaq :: 6930p: Un2400 Wwan Only Works When Battery Inserted
Aug 29, 2009
I am using a un2400 wwan UMTS modem on my HP 6930p (WinXP, SP3) and noticed that it is automatically deactivated when the battery isn't inserted into the laptop (PIN Code is also deactivated on the SIM card). Once the battery is installed, it works without any problems.
Can anyone confirm this being a normal issue with this modem?
(the Huawei EM770 modem on my eee 1000HG works with or without an inserted battery but it also doesn't require the firmware to be loaded first, so maybe these two can't be compared..)
I have a Dell XPS m140 when I use the ac adapter without the battery inserted the laptop powers up fine. When I insert the battery and the ac adapter the adapter turns off after a few seconds. If I unplug the ac adapter and do it again the same thing occurs. When I remove the battery and use the ac adapter after I unplug it from the wall the laptop will power up again. I don't know if the ac adapter is not strong enough to charge the battery and boot up. I tried just having the battery in and not turning on the laptop to see if the battery would charge and the ac adapter turns off after a few moments. Can a battery have a short in it to cause this or is the adapter finally going south? I tested the adapter and it shows 19.5v. when the adapter light goes off it tests 0. After I unplug it and replug it, it shows 19.5v again.I don't know where to go from here, new battery or new adapter.
My 4-year old Dell Mini 10 has started flashing orange just after bootup & then turns off. (Adapter LED is solid white, the flashing orange is the one at the front.) Removed the battery for an hour, since some postings say it's probably just hot; when it's reinserted the problem returns. But when I run it on AC power with the battery out, no problems.
This machine has had a weird life for a laptop, in that it has almost never been taken anywhere -- that is, it has only rarely run on battery power, and the battery has been fully discharged only a handful of times.
I'll be replacing it soon regardless, but for the month or so between now and then, is there anything wrong or unsafe about running it with no battery in the bay?
The fan is always on. It doesn't disturb at the lowest level, but it ramps up every 5 mins or so for 2 or 3 seconds. I find that ramping up disturbing and would like to disable it. Considering how cool the air coming out is compared to laptops I have had in the past (Thinkpads and Toshiba) I would say HP is being conservative with their settings.
I wanted to upgrade my ram in my 6930p Right now I have to temp ram 2gb 667mhz. I want to upgrade to a 800mhz but I don't know how much I should get I wanted 8gb but I'm not going to play much hard core games so this might be to much.
What do you consider to be the best overall memory needed for games and App.
I'm aiming to buy a new HP EliteBook 6930p in January 2010. There are a few issues that I've read about which concern me, however.
Some of these I have read have been fixed, although I haven't seen much in the way of confirmation of this. So I'm wondering, of these, have any been fixed in the latest production models of the 6930p?
1) The lid takes too much pressure to shut and/or doesn't stay shut.
2) The battery is loose when attached (any danger of it falling off?)
3) CPU whine -- I'm planning on getting it with a P8800 and ATI HD 3450 256MB, if that matters.
I just swap out the the motherboard for a working one and change all the components inside and the monitor don't power on. All the lights show the fan spins but no picture. Before I did the motherboard swap the same thing happen. The shop I took it to said it needed a discharge from the build up over time. After the unfix-able corrupt bios problem I was force to swap boards. How do I do the static discharge? I ground myself with a steel pipe took apart everything put it back together still the same.
I bought HP 6930p with ATI graphic card, WIN 7, and connected to the external display 24" (1920x1080) trough VGA port. There is a very noticable blurry and annoying image on external display. I tried different settings, but nothing did not help. Is there any solution to this problem? could be my graphic card or vga output damaged? Since with my 4 years old toshiba notebook, image was clear.
Has anybody docking station and is DVI output working fine (clear image)?
I was looking at the new Elitebooks today and saw that there are now 8xxx series machines with 14" screens and that there is not a 6940p. Is the 8440 intended to replace the 6930? Also, why is the screen on the 8440x 14.0" rather than the 14.1" size that appears to be the norml? Another change in aspect ratio?
I'm thinking about buying the HP 6930p Elitebook. One concern I have is that it only has a VGA port and no DVI, HDMI or Displayport for connecting an external monitor. I plan to connect the laptop regularly to a 24" display.
I thought one workaround might be to get a docking station for the laptop, which has a DVI connection. As the laptop connects to the docking station via a different port, I assumed a digital video signal would be sent. However, when I called HP to confirm if this was possible, they advised me that as the laptop only outputs VGA, even when it is connected to the dock, the only thing I could do would be to connect it via the dock's VGA port; it couldn't be connected via DVI. Is this correct? I have received incorrect info from HP and Dell on more than one occasion, so I wanted to check on here. Would the DVI port work on the dock or could I only use VGA?
Also, if not, how much better would a DVI or HDMI connection be versus VGA for that size of display.
Have D420 here and was thinking if it's possible to use WWAN slot for any other mini pci-e cards like SSD or video decoder. Now Dell docs state not to mix WLAn and WWAN cards between their assigned slots.
My current x230 is set to "Automatically optimize for battery lifespan" under battery maintenance. I read that for this settings, it'll set your battery to hover around 80%~ base on Lenovo forum under w530 section. However, i'm always seeing my battery at 100% when AC is plugged in; Remaining capacity: 62.47 wh ; Full charge capacity: 62.47wh. Is it suppose to be lesser? I suppose it not healthy for the battery to be constantly kept at 100%. Any x230 users experiencing this too?
Would like my battery to last at least 2 years. usage :70% AC plugged in,30% on the go.
I just got a new Elitebook 6930p and its a fantastic laptop other than the dreaded "CPU whine" as some call it. Most uneducated people believe it is the CPU that makes this noise but in reality this has NOTHING to do with the CPU. Its the power components like capacitors and coils that make the Piezoelectric Effect which causes the noise.
I could not bear the whine noise after a few days so I took matters into my own hands. Sure I read about stopping the C1-C4 states in Intels speedstep but thats not a proper solution IMO since battery life will suffer. So how can we mask or cover up this annoying noise? How can we seal it inside the laptop so it does not reach our ears? I have the solution!
Seal it up all the power components with silicon sealer. Silicon sealer is perfect as it does not conduct electricity. These components do NOT generate any heat either.
As soon as he leaves, the laptop just shuts off. I try to turn it back on, and all three of the lights (caps lock and number lock and the other one) plus the three lights on the hinge light up for 5 seconds and then shutoff.
On the few times I have been able to get it to start, if I moved it at all, the entire system would freeze and I would get a white screen with a message that says "You have inserted a module into the D-Bay attached to your docking station, but this module is not supported by the D-Bay
I've decided to purchase an HP 6930p. I will mainly be using it for business - Word, Outlook, the Internet, Excel etc. I won't be playing many games on it (if any) or be doing any video editing. I have a 24" display, which I can use for any graphics work (Photoshop etc). I'll be using the laptop about 50% of the time away from the office - at libraries, coffee shops, or other offices/meeting rooms.
I'm trying to decide which resolution to get - the WXGA or WXGA+. I know a lot of people on these forums recommend the higher res screens; however, I imagine a lot may use their systems for games, video editing, CAD, web work etc. I'll be doing intensive office work. For a 14" business machine, what is the best resolution?
Also, if anyone happens to be a 6930p user, is there any difference in brightness between the two screens? That could be a factor.
I have a older HP 6910p laptop that I am prep'ing for use in my Digital Camera bag. I thought it might be nice to install a WWAN card, in the laptop in case, I am out and need access to the internet in some place that does not support Wi-Fi and the like.
I am looking at the WWAN card from ebay: [url]
I have a couple of questions:
1) My laptop has two Antenna leads in the port area for the WWAN card and the MC8775 has only 1 Antenna connector, will it work OK with only the one Antenna lead and which of the two leads should I connect?
2) Will I be able to use the SIM card from my iPhone in the Laptop with no additional plan or service then the data plan that is already provided by the iPhone/AT&T plan?
3) How does the GPS function work on these WWAN cards?
My Dell Latitude E6400 laptop reboots when inserted in the docking station. I can run all day and say I hot dock it out of the docking station and go away for half an hour. While away I use the laptop. When I return I snap the laptop back onto the station and.... it reboots! It started about a week ago. Always worked before. The peripherals are two displays, ext kybd, mouse. No USB stuff. Ethernet connected in the dock. This setup is unchanged for months now. Docking contacts clean. Under laptop too.
BIOS is most recent (did a few months ago). I reset defaults in the BIOS today after looking for any setting that may change this issue, but no improvement. Device Manager has nothing relevant either. What's wrong? The hard reboot is really bad as I lose all my in progress work and get all these Auto Recover files to manage... and logins... and restart apps... I'm not interested in putting the computer to sleep between transitions, as it has always been working flawless up to last week.
I this will happen almost everytime if the machine has been in use for some time. Inserting an SD card (4GB Canon format) a BSOD is virtually guaranteed. After a new boot up it works fine but catastrophic if not since all info is lost and nothing is closed.
I looked at the dump file and the FASTFAT.SYS is the cause of the crash. This is a very old driver used in Windows 7 and there are numerous issues with it in many forums dating back even to XP. There are no crashes introduced by any other device or USB key/drive connected. Only the SD card.
I thought it may have be due to the USB controller being turned off for power conservation but even after removing the ability by toggling not to turn off to save power to the USB devices it still crashed the very next time I used it which was days later. The system was plugged in as well as it usually is.
I can do the same thing on my old notebook with its internal multicast reader running Window 7 32 bit and it does not have a problem. The Thinkpad does with Win 7 64bit. I am always conscious of a BSOD occurring if I dare plug in my camera card. This renders the port useless since I cannot afford regular crashes and a card reader externally may have to be used.

I am having some strange problems with the backlight on my dv9700...I started a thread about this maybe 2 months ago but the backlight for whatever reason started working again and I didn't have too many issues with it until recently. Lately the backlight has only been working when it is plugged in...If I unplug it but leave the lid open it still works but as soon as I close the lid and open it again its out until I plug it back in and open and close the lid. Now I can't get the backlight to work at all except it lights up for 2 seconds or so upon closing and opening the lid. I removed the display bezel to access the display inverter and check for any loose or damaged connectors but they all appear to be fine...unplugging and plugging the display panel cable connector back in also causes the backlight to work for 2 seconds and then go out again. Besides the backlight issue the laptop seems to be working perfectly fine...can anyone help me figure this out? I should mention that I upgraded this laptop to Windows 7 right away when it was released.
