SOURCE: Cmos battery

You must enter the laptop internally that is.  In some laptops it is soldered to the motherboard be prepared to find that.  Did you know it takes a long time for the battery to be stuffed because.  Are you certain that the problem is the battery?.  If it is stuffed your bios would have resetted itself to the default settings and will not hold your settings.

Bio password

Here is a complete guide to disassembly of the VGN-SZ laptop.
The trick here is to get to the CMOS/BIOS (referred in the manual as the 'reserve') battery. Remove this battery and leave the unit with no battery, A/C power or CMOS battery for an hour or so. Then replace the CMOS battery and reassemble. Power it up. Its going to 'yell' a lot since the BIOS was flushed and all information will have to be put back in. However after you do this, you should be all set.
Hope this helps!

Need to disable cmos password protection (ex-girlfriend issue!). Does it need to have a jumper disabled or is there another way? Thanks

After a quick read-through of the user manual for the P505-S8950, the only way to discharge the CMOS memory seems to be removal of main battery and power cord for and extended period of time in order to cause the CMOS battery to discharge.
There may be a way to open the laptop and remove the CMOS battery to speed-up this process; however, my previous experience with taking apart a Toshiba laptop led me to the realization that they are not designed to be easily disassembled -- I had a heck of a time reconnecting the display data cable (I had to use a chopstick and have a lot of luck to get it back together).
I would suggest opening each of the access doors on the bottom of the computer in order to determine whether or not you can get at the CMOS battery that way; otherwise, I think your stuck with waiting a LONG time for the CMOS battery to discharge or VERY carefully disassembling the laptop.

Need one time bios password for sony vaio laptop, electrical storm jacked up the operating system lost bios password, need to run diagnostics model numbe vgn nr140e can you help

in order to reset the bios password you will need to remove the cmos battery and leave it out for about 15 minutes. This allows the stored up charge in the capacitors to dissapate, and after they discharge is should be reset back to original factory bios setting.
once into your bios, make any changes needed for specific hardware before you reboot computer and go into diagnostic testing mode.

There are 2 ways you can reset your bios2_bing.gif.

1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in2_bing.gif your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete

This is a great troubleshooting2_bing.gif step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.

Please let me know if you have any further questions or concerns.

Power problem

Hi Odek, You have to short the CMOS reset pins on the motherboard. You can find the location of these 2 or 3 pins on the motherboard manual. For Enisco's problem the monitor power cable is not properly earthed. You can either earthed it by connecting a wire from any conductive part of the monitor to a earth pin on the wall plug or something conductive near the monitor like a will sill. I would probable change the wall plug or the faulty power board. regards

LX7 Mouse False Low Battery Reading

I have found that sometime these Rodents seem to have a "Taste" for a certain "Type" of AA or AAA cell, one needs to get the Highest Discharge rate one can get. Often the "Brand" of Batts supplied are the "Only" ones that seem to work 100% alla time? I have had similar problems with customers B4, and I find the Varta series of battery to be great. & remember just because you bought them "New" don't mean the Batts are always "Fresh", get batts from a place that has a high turnover.
