BlackBerry Smartphones loading very slowly via USB power supply laptop

When I use the wall charger, my fine storm costs.

But if I connect it with the sync cable to my laptop - laptop is turned on with the BB Desktop software running (and I can confirm that I have a backup of the BB Desktop software then the drivers seem to work), the storm is charging is very very very slowly or not at all.

Is it supposed to load OK via USB to the laptop power?  How can I go on troubleshooting this?

Your question is not a problem, but normal and the answer "why" is simple. Wall charger puts out simply more power that the USB port on your laptop needs to (or can). In general, any single USB port is 100-150mA (and can be lower if your running on batteries and the system is allowed to control the ports), while the wall charger is to switch off a little more (700mA)... constantly.

Not to mention that when connected to the laptop there is communication that passes between the device and the computer, especially if you use the Desktop Manager, which makes peripheral 'work' and try to reload at the same time. Sometimes the ' workload ' can be greater than the rate of charge, so why he does not pay at all.

IMHO, load your device with the supplied charger. Only use your computer to charge your device in case of emergency. If you insist on charging the system with your laptop... Plug in your laptop computer, close the Desktop Manager and Device Manager and it should load a bit faster.

  • Slow blackBerry Smartphone Super battery charges via USB

    I noticed that when I charge the phone using the wall charger, it will achieve a full charge in about an hour.  USB charging takes however as three hours.  Why is this?

    Two or three hours I guess. Of course, it will depend on your level of battery at the beginning. I just plug mine every night in a wall outlet, have scheduled Quickpull to run at 4:30, and I have a fully charged device and reset every morning.

  • After xp reformat, pages load very slowly

    Recently reinstalled XP, I know it's difficult to diagnose problems with computer through forums, so I'm providing as much detail as possible. I have the same firewall, some of the same programs, same version of firefox, different av (disabled for a test, no change). I use a d-link adapter in a home network, there is no change, & there is NO MALWARE on here. I can't understand why every site I click loads so SLOWLY. Before the reformat, when I had a few problems of operating system, the pages loaded quickly. You would think that after a reformat, its similar with a new pc once again, that this would not happen. The pc boot faster that before, without problems for you to connect to any site, just very frustrating having to wait anywhere from 10 seconds to 45 seconds for a page to load. I understand there are different variables that come into play, to connect to a site, but it happens on all my favorite sites & anything I click on that. If anyone can help, I'll check back on here regularly to answer as soon as possible. THANKS for your time/help.

    Let's just double-check something basic with the network... just to play it safe.

  • BlackBerry Smartphones 9650 on network via laptop Get

    Thank you for taking the time to read my question.

    I wonder if it is possible to get my Blackberry on the LAN to my office through my laptop. Maybe connected to my laptop via USB or Bluetooth. What I have is how to get my laptop on the internet via tethering with my Blackberry.

    I have a wireless router at home and can get my Blackberry on this network (wifi), but my office doesn't have a wireless access point, and I would like to know if I can still get my Blackberry on the internet like that.

    Thanks again for your time.

    You must have a Wifi card wireless in your laptop and connect to your BlackBerry via WiFi.

    There is not a data cable or bleuthooth connection.

  • Initially Web pages load very slowly, but are a lot faster if I stop and reload the page

    Whenever I have initially load ANY page of a Web site, the first page really takes a lot of time to load. All pages of this site is loading very quickly thereafter. I also noticed that if I stop the loading of the page, immediately after my first click and then click on reload, the page loads almost instantly. I am currently using Firefox 20.0.1, but this problem has occurred for a while... at least as far as Firefox 19. According to my research, I've tried a bunch of suggested solutions, but nothing helps... including: off hardware acceleration, don't select any proxy, disabled ABP, etc.. Any other suggestions would be greatly appreciated. Thank you!

    Hello stw203, maybe try to reset all the related settings in your network configuration. enter Subject: config in the bar firefox address (confirm the message information where it appears) & are looking for any preference, starting with the network in bold (= set of users) - do a right click and put these entries to their default value.

    @xxxlx,

    Hello and thanks for the display on the HP support forums.  You may need to activate the quick start upward with 10 Windows.  Your laptop may not be happy with the new operating system to 100%, so you may need to make some adjustments.

    Quick start - turn on or off in Windows 10

    Another thing to try is the Windows Update 10 troubleshooting tool.

    Windows Update Troubleshooter

    If that fails to solve the problem, you can restore the earlier version of the operating system until the new updates will be available from Microsoft and make sure there is a complete list of drivers for Windows 10 for your system.

    Please post back with the complete model and the product number of your system, so I can give you the link to the support page for your system.  Here is a link that will help you find this information.

    Computers how can laptops HP - I find my model number or product number?

    Please let me know how things are going and post back as soon as possible with the model and product numbers.

    Thanks again for posting and have a great day.

  • iPhone 5 c will not charge via USB on the laptop?

    Hi all.

    I have an iPhone 5 c and as about a week ago, does not charge via the USB port on my laptop. He sees very well in my wall sockets and Sockets USB as well, but not in my laptop. I have an Acer laptop running Windows 7. Windows is up to date, iTunes has the latest version installed. Whenever I plug in my phone, one of the following conditions occurs:

    (1) does not have

    (2) noise "plugged" USB lights, the window on the lower right, tell that a USB device has malfunctioned

    (3) (rarely) of phone calls after I tried several things

    What happened is I would plug my phone, she would charge via USB, iTunes opens automatically, and "trust to this computer" popup would come on my phone if I had unlocked it. None of this is happening now. I did the following to try to remedy:

    (1) power cord iPhone replaced (it was time for a new anyway)

    (2) uninstalled and reinstalled iTunes

    (3) restart computer and phone probably 29856 times

    (4) device Manager... nothing comes up at all, not even the unknown device. RARELY the unknown device comes up, then I get a "Code 10: this device cannot start" error, but it is * in a handbasket just trying to get to THIS point! and IF I do what they say to do to correct a code 10 (uninstall all USB and restart the computer, then USB devices hook to the top one at a time), so I'm now at my problem of a communication that don't meet pluse between my phone and PC

    5) tried to the registry editor, but not "upper filters" option rises

    (6) virtually every other option on this thread of 5 pages iphone not recognized by Windows 7

    Help, please?

    The USB port of your laptop does not provide sufficient power to recharge the phone. It is a hardware problem with your laptop, not the phone.
