Thanks for your help - I am sure that many appreciate your efforts here.
A couple quick points...
1) The mods are removing email not to stop you guys from sharing files, but as part of our normal policy of not having public emails - we have trouble with spammers here as it is and want to protect our community members as much as possible. Please use private messages to exchange email.
2) If you download and apply a Lenovo BIOS from our support site, that does not void your warranty. If you apply a BIOS of unknown origin obtained from a 3rd party site and have trouble with it, or trouble results from it's installation, that is not a Lenovo warranty situation.
3) We are looking into the discussion here and appreciate the observations that have been shared...

Thanks Zehnsteine for your help and the link to the other thread. I have done what others did in the other thread but I'm still getting these stutters randomly. There's something with the power saver and balanced power plans that causes my CPU usage to spike up to 100% and that's where my laptop stutters

where should Y460p / Y560p owners obtain another BIOS to fix the sound dropout issue
caused by defective BIOS vers 3FCN19WW presently installed on their machines?
At present there is no BIOS available for download on Lenovo IdeaPad Y460p / Y560p Drivers & Downloads site:
Best regards... Zehn

Good question! As you note (I checked yesterday when I posted) there is no updated BIOS available for download for these system on our support site.
We can work with appropriate teams to get a latest version provided for download, but I'd like to get an example system to test for this issue and then try to get a copy of the BIOS you have provided others here to test.

great , this sounds like there might be a BIOS available for the Y460p/Y560p from Lenovo support in the near future,
could you also consider the possibility to enable the AES-NI feature in this upcoming BIOS... PLEASE.
BTW... BIOS version 3FCN17WW64 and relevant personal information sent.
Best regards... Zehn

I'm facing a problem to install 3FCN17WW64 in my laptop.
Please refer the below pictures
my laptop is very slow, it needs more than 2 minutes to start up the windows xp.

please try to troubleshoot your sound stutter issue a little further...
download 'LatencyMon' analyzer tool (does not support Windows XP), close all running programs,
go off-line, disable anti-virus software and firewall, switch off WLAN with the little switch on front of laptop,
then in 'Lenovo Energy Management' select High Performance, under Display and System tab set
everything to Never and Maximum CPU Speed to High...
next do run LatencyMon until the stutter occurs and then look up what was causing it.
Note... this is a rather complex tool, so I suggest you to read all the information and explanation
offered on the website.
obviously BIOS version 3FCN17WW64 can possibly be flashed running a 64 bit Windows only.
I had installed Win XP-32 bit for a short time only, it seemed not to work well on my Y560p,
so I returned rueful back to W7-64 bit.
How about the workaround I suggested previously to you?
Maybe better to start a new 'Y560p & Win XP-32' topic thread.
I assume before flashing the BIOS you tested your Y560p without battery pack attached and on mains
power only and the single split-second sound dropout once every 65 seconds did not happen then.
What version was your original BIOS and what version BIOS did you flash?
Why do you want to roll back to the previous BIOS?
May test further with 'LatencyMon'... see above.
Good Luck... Zehn
