Re: SOLVED_Y460p/Y560p Sound drop out once every 65 sec

Zehnsteine,

 

Thanks for your help - I am sure that many appreciate your efforts here.

 

All,

 

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...

 

Best regards,

 

Mark

Re: workaround for y460p/y560p sound stutter

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

Re: SOLVED_Y460p/Y560p Sound drop out once every 65 sec

 @ Mark_Lenovo

 

Hi Mark,

 

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?

 

Please advice!

 

At present there is no BIOS available for download on Lenovo IdeaPad Y460p / Y560p Drivers & Downloads site:

http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=611900

 

Best regards... Zehn

Zehnsteine,

 

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.   

 

Thanks!

 

Mark

@Mark_Lenovo

 

Hi Mark,

 

great Smiley Happy, 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

Re: unSOLVED_Y460p/Y560p Sound drop out once every 65 sec

intel does not know how to fix the upper from the lower flange from beeing on low power or high power usage. This is the SMI stuttering we do get. Means in fact, uncontinouges effects during any OP we do. The movie streams do. But without an perfect calculator as an intel cpu or amd is like to, that does not work. ACPI is a system to a computer normaly without interruptions as known from the older DOS Computers. The point is to get it working without Interruption. Currently it does not work. Processes are well done, but with stucking. Turning the cpu to not well known settings does fit the problem. Even Windows does benfit from that. In fact it means to overclock an device ... not the cpu. each mobo is fitted with it's chipset - that is the goal - to reach each component within it's time -

Re: SOLVED_Y460p/Y560p Sound drop out once every 65 sec

Hi...

 

@TheStingray,

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.

http://www.resplendence.com/latencymon

Note... this is a rather complex tool, so I suggest you to read all the information and explanation

           offered on the website.

 

 

 

@Wschan,

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.

 

 

 

@ KabkaCaana,

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.

http://forums.lenovo.com/t5/IdeaPad-Y-U-V-and-Z-series/workaround-for-y460p-y560p-sound-stutter/m-p/...

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
