Mostly this problem comes up if you dont shutdown your computer properly as in by offing it by holding the power button and stuff like that. What you can try doing is when you on the computer it should let you choose if you want to go to the BIOS menu or System Recovery and you go to System Recovery and if you would like reboot the whole computer or just choose to repair the windows and it will reinstall the windows files only which should take care of the problem.

The BIOS password is probably the Power On Password. This method may not work. Remove the BIOS battery for 20 mins until the charge in the BIOS is depleted. Insert the BIOS battery go into the BIOS setting and set the Date and Time etc. If this does nor work then the BIOS password is stored on an EEPROM chip and removing the BIOS battery won't work and there is probable no backdoor passwords. The Sony support maybe able to offer a solution, check the support WEB site..
[CHANGE YOUR CMOS BATTER WHICH IS INSIDE YOUR CPU CASE] I do not think you fixed the CMOS battery - (backup battery = CMOS battery) According to the error codes, you have a dead backup battery and the time is not set. Makes sense? 161 (Dead battery.) 1. Go to Checking the Backup Battery 2. Backup battery. 3. System board. 163 (Time and date were not set.) 1. Set time and date. 2. System board.
Go to www.ibm.com Find and download the user manual, and the "hardware maintenance manual." Do you know how to get into bios/setup?
Start with the machine OFF. HOLD DOWN and CONTINUE TO HOLD THE "F1" key. WHILE STILL HOLDING "F1", turn the power on, and CONTINUE TO HOLD "F1" This will get you into the bios "setup." You should check the date, bootup order, etc, and reset. I would check the "wire" you think you reconnected---you may just not have actually reconnected it. The "hardware maintenance manual" shows you how to maintain this machine, and it explains the meaning of the error codes.
This will get you started on looking for the manual:
Yes, but each time you start the computer you have to enter the BIOS to set the proper time and date. This is essential for certain progra,s to run correctly, when the computer shuts off, everything will be reset once more.
The bios settings are being lost during offtime. This is due to the cmos battery being dead. Most units have a round 3-volt lithium battery in a clip/holder. A few use a rechargeable battery that recovers if the unit sees frequent use. Can you verify the model number of this unit?

161 - Dead CMOS battery.
163 - Date and time are not set clock not updated.
Replace CMOS Batt: On the bottom of the laptop you will see a screw
that holds the memory cover on. (Next to the main Batt) Remove the
screw and cover. The CMOS is plugged into the motherboard it is yellow
and round tucked in the side of the case. (note how the black cable is
towards the center of the laptop and the positive red cable is towards
the side of the laptop). Remove the cable connector from the
motherboard and pull out the old battery. This can be done by either
gently pulling on the cables or using an object like a toothpick and
gently tugging at the old battery to free it. With the old battery
removed plug in the new battery with the black ground cable towards the
center of the laptop and the red towards the side of the laptop. Insert
the new battery into the space the previous one set at. Reconnect the
memory cover and turn on your laptop. You will have to set the time and
date and may have to cycle the computer (reboot) a few times. You can
get this battery (CMOS) on eBay or at a computer store they are only a
few dollars. (5-8) Good luck in your repair! you need a cr2025 to replace it you have to pull the tabs of the old one off and tape them to a new cr2025 battery. then Start with the machine OFF. HOLD DOWN and CONTINUE TO HOLD THE "F1" key. WHILE STILL HOLDING "F1", turn the power on, and CONTINUE TO HOLD "F1" This will get you into the bios "setup." You should check the date, bootup order, etc, and reset.
