Good afternoon!
It sounds like either the LCD inverter, or the LCD back light, has gone bad. If you want to try to replace these items yourself, please follow the lick given below for pictorial instructions on how to do this.

Sony vgn-bx540b bios master password


If you are not the one who set up the Bios password, your options are to keep guessing or reset the cmos.

To reset the cmos, open your laptop and look for a small, silver, circular battery. Make sure everything is unplugged and remove the battery. Then, simply place the battery back into the computer. This should reset the bios and allow you to access it.

Hope this helps!

I have problem with vgn-bx540b model sony bios password unlock plz tel me how i unlock my sony laptop plzzzzz tel me how i remove bios password


Hi,


Welcome to FixYa!

Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,


Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...


Hope this will help...Thank you for using Fixya...

I have a Sony VGN-CR220E. The backlight works and the screen gets bright but the video display has nothing but lines and some color but not in any reconizable paterns. Any advice?


The LCD screen is bad, or the video cable from the motherboard to the display is loose and needs to be reseated back in place. But before we call it ! hook an external monitor to the video output at the back of the laptop, If the monitor is good it is the laptop screen, If both show the same problem it is the video graphics card that is apart of the motherboard.

My lcd is really bright then all these black blocks coming from the right going to the left no pictures, laptop works with a external ok. What am I looking for?


Hi,

Please restart the computer and press the F2 key to access the BIOS setup. If the issue persist in the BIOS also then the issue is with the LCD screen, in that case service will be required to replace the LCD screen. You may either contact Sony Service Center at:

https://eservice.sony.com/webrma/web/index.do

Or you may also contact your favorite hardware vendor.

Based on the information, it seems that those are dead pixels and a LCD replacement will required.

The following are the Display part numbers:

A1062138A- Sharp Display Model# LQ170M1LA04
A8119991A - LCD Harness
468257801 - LCD Hinge (L)
468257701 - LCD Hinge (R)
468238001 - LCD Hinge Cover
147862922 - LCD Inverter

Scroll pad not scrolling on my vaio e series laptop


The computer model VGN-BX540B is shipped with XP OS. Follow the steps mentioned on below link to check of the scroll function of the touchpad is enabled.

http://www.kb.sony.com/selfservice/documentLink.do?externalId=C424522

If it is enabled and still the scroll is not working, reinstall the touchpad driver and check: Dowload the touchpad driver from the below link:(XP)

http://esupport.sony.com/US/perl/swu-download.pl?mdl=VGNBX540B&upd_id=2000&os_id=7

If you have upgraded the OS to Vista, Follow the steps mentioned on below link to check of the scroll function of the touchpad is enabled.

http://www.kb.sony.com/selfservice/documentLink.do?externalId=C539250

If it is enabled and still the scroll is not working, the issue is most likely to the limitation of the driver which will not work in Vista environment.
At this point what I will suggest is to download and install the Touchpad driver for different model with Vista OS installed in it.

http://esupport.sony.com/US/perl/swu-download.pl?mdl=VGNBX760&upd_id=2748&os_id=29


As Sony has a model check code for all the drivers, use Universal Extractor to extract the setup file and run it. This will work.

Thanks

LCD monitor


That's and early sign of a wearing out LCD... Too early maybe something bad happened, that's the start.

Find someone who has the same brand and has a good LCD but already unusable, or junked, and use it as a replacement to your LCD...

That will help... Vote Fixya on that.

Sony Vaio VGN-BX540B Screen Resolution


you should be able to get a resolution of 1280x800 for a standard screen size of 15.4" The 1280x1024 will be more for a large screen high definition lcd tv when connected, which you will then find will become available to use as a screen size, although only through a dvi connection to the tv as a normal vga connector will only give a maximum screen size of 1024x768.
