Efficient Method to Update Sony Drivers

There are numerous of common warnings and also other messages which you might get in the driver updating process, several of which I've paraphrased and listed here along with advice on what you can do:

QUESTION: the computer now have to power-on a couple of time just before it may possibly start-up, but it really will just shutdown a couple of minute afterwards.the computer is linked right to power point.but a while it might final one particular hour right before shutdown yet again.any tips will likely be appreciated. thks.

ANSWER: Let us isolate the issue by doing a power cycle: Eliminate the battery and all peripherals -> push and hold the power button for five seconds OR, in the event the battery just isn't removable, take out all peripherals -> seem for your battery off button over the base in the laptop computer -> press the button for 5 seconds -> you may utilize a safety pin.

Method to Update Driver with Device Manager

  1. Driver updates for Windows 10 and many devices (such as monitors, printers, and video cards) are automatically downloaded and installed through Windows Update.
  2. While it's likely you already have the most recent driver, if you're having trouble with a device, you can try fixing it by updating the driver or reinstalling it. Here's how:
    • Select the Start button, type Device Manager, and select it from the list of results.
    • Expand one of the categories to find the name of your device, then right-click (or tap and hold) it, and select Update Driver Software.
    • Select Search automatically for updated driver software.
    • If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.
  3. If these steps don't work, try reinstalling the driver: Open Device Manager, right-click (or tap and hold) the name of the device, and select Uninstall. Restart your PC and Windows will attempt to reinstall the driver.


To download and update the driver for SONY VGN-Z550N yourself (If you are a geek)

It's best to let Windows install device drivers automatically. But if Windows can't find a driver for your SONY VGN-Z550N, you can look for a driver on the manufacturer's website of SONY. Driver updates are often available in the support section of such sites.

Once you find the updated driver, follow the installation instructions on the website. Most drivers are self-installing—after you download them, just double-click the file to begin the installation, and then the driver installs itself on your computer. But make sure your are downloading drivers from a safe website to avoid virus attack or registry corruption. Download a professional driver updater or find a geek to help you.
