My Vaio doesn't keep correct time and date. I've been told to replace the internal board battery. But don't know where it is inside.
I took off the back cover but alas I don't see it. It is a PCG-V505DC2P by Sony

Steve - I checked the User Manual for your model, and there is no mention of any CMOS battery. CMOS batteries are no longer used in laptop/notebook computers.
Instead, there is a new technology, in which a capacitor slowly discharges to maintain a trickle current to the CMOS (Complementary Metal Oxide Semiconductor) chip.
This new technology is called [i]SmartSocket[/i], and utilizes what's called nVSRAM (non-volatile static random access memory). An [i]electrolytic capacitor[/i] replaces the CMOS battery. The old CMOS batteries are also referred to as RTC (real-time clock) batteries:
My old (year 2000) Sony notebook had a CMOS battery, but my current T-series notebook does not. Since I couldn't find any mention of it in your User Guide, I must assume that yours uses SmartSocket technology. Also, you should have seen the watch battery if you removed the back cover.
Regarding the time/date glitch, you should be synchronizing with Windows, which seamlessly keeps your clock current. Double click the time in the system tray, and navigate to the menu tab [i]Internet Time[/i]. Be sure there is a check mark in the box in front of [i]Automatically synchronize with an Internet time server[/i].
I use [i]time.windows.com[/i], but you can use [i]time.nist.gov[/i] (which I have found less reliable). Also be sure you that have the correct time zone, and that there is a checkmark in front of daylight saving correction.
Check out this TR thread:
Hope this helps. Post back if the glitch persists.
