SOURCE: sony vaio VGN FJ290P password reset sony vaio VGN FJ290P
I have set the password for administrator when i entered the bios set up. you can change its setting but not the configuration unless you've entered the password. you can't change the password with a new one if you cant enter the old password. Next time dont forget your password because laptops has its security even when stolen you cant open its bios set up if its protected by password. CMOS battery is in the mother board. You need a service technician to open your laptop to reset the bios setup battery.
SOURCE: I need steps to replace Fan for my Sony VAIO VGN-S460
the fan is screwed together with the motherboard, the only way i figured is to separate it is completely unscrew the motherboard, cd drives.....then unscrew the fan from the bottom side of the motherboard....
i took the fan out just today, wantted to add some lubricating oil to it, but then can't manage to separate the blades & expose the centre
how much did the replacement fan cost? i am in canada, not even sure sony stores here have it.
SOURCE: How to reset BIOS password on VGN FE880E
If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Good luck.

I trust that you have purchased the entire fan assembly as they are inseparable from the heatsink. You must disassemble the entire laptop in order to remove the fan assembly. they are two screws that are below the motherboard that must be remove in order for the fan assembly to come apart.
If you cannot achieve this yourself, or lack confidence in your ability to rebuild the unit after, you can send the unit to us at www.cowetacomputerstore.com and we will accomplish the desired outcome. We have worked on this system resolving this very issue.

Hello,
There are 2 ways you can reset your bios.
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 in
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 troubleshooting
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.
Thanks.
