Is this strange noise a bad sign? Is it normal?

2011-12-11, 16:08 PM

Hi,

 

This is another issue with my x120e (05962RU).

 

When the computer is turned off, I hear an electrical(?) noise coming from the board. It's a kind of continuous buzz. It's better audible when you put the ear on the back of the computer and I can hear it with the battery or AC only plugged in and with both plugged in. The only thing I tried was disabling the active USB charger. Do not change anything.

 

 A few days ago, at a repair center I replaced the motherboard, because it was dead (never explained why). Strangely the old one had too the same noise.

 

Questions:

 

Is this noise normal?

 

Can anyone, please, confirm if this is an isolated case?

 

It's only me? Or your x120e makes this noise too?

 

Thanks anyone for your help.

UPDATE: Visited a service center yesterday. Now my laptop is in another round of service... three months old laptop, and already at the service center twice. Very, very, very disappointed! The first board was dead after a month. Was this the cause of that? No answer. How many times will my laptop suffer a repair? What's the point of spending a lot with the hope to avoid troubles, and being frustrated after a few months of use? :smileysad:

 

Updates: removed comments that were based on emotional frustration at that time :)

Hi again,

 

I'm not asking to have an expert answer to my problem.

All I need is anyone with an x120e to kindly check on his/her laptop if the same noise is audible on the back of the laptop when it is powered off.

 

Thanks again for your help

Can't say I've ever checked that closely, let alone been in an environment quiet enough to check, but a buzzing implies a transformer still operating. Why it would do that, I've no clue, but I can't say I've heard anything major enough to worry me when it's off.

To my knowledge, there are no actual transformer components in the power supply or the laptop. In this day & age, it's all solid state switching power supplies.

So a buzzing or humming should not be as a result from a transformer.

You're probably right about that much, though to even hear any sort of sound that isn't imagined coming from a powered off system would imply that it hasn't fully powered off.  Now, if it makes a sound when no battery is connected and no power is supplied, then I'd be worried (all things that rely on a toggle switch require power to even recognize the switch).

Hi, thanks for your thoughts.

 

Yesterday I tried disconnecting everything I could from the board: Hdd, ram, Bios backup battery, the wifi module. The noise after removing all these, became a bit lower, but still there.  Only removing the battery make the noise disappear (logically).

 

I do not want to be paranoid, but since I already had to change the board at a support center, I'm afraid that this can be repeated (hope not)

I have no such noise.

 

Could it be the wake on lan function?  That keeps juice to the mobo even off.

 

Check the bios for this and since I can't imagine anyone actually using it, disable it and see (or hear) what happens.

Dear everyone :-), sorry to bother you again,

 

If you have an x120e, can you kindly do me a favor and actually check if in a quiet environment with the computer turned off and the battery only plugged in you hear any noise from the board???

Thanks a lot for your help.

Regards

abvasili

Hello

 

I can hear that noise on my friend's x120 when always-on USB and WOL is enabled or when the computer is sleeping.

When it's completely off with everything turned off, I can't hear anything.

 

I have the same situation on my x220. I was surprised to hear a decently loud buzzing when it was sleeping in a quiet room the first time! No wonder the battery drains like crazy when it's sleeping.

 

Edit: Both situations were with battery only, never tested with AC plugged.
