t540p power supply problems

2013-12-17, 20:29 PM

 

 

 Some times, when the 135 w power supply is attached, I get the message from Lenovo Settings Power

 

"Lenovo Settings Power has found a problem with your power supply and has activated the Airplane Energy mode"

 

Any ideas?

 

Kind Regards

 

Nik

Hi there,

 

we have got the same problem here.

It is impossible to use powerpoint, because the message pops up and/or the brightness is going down and up...

 

We need a solution very fast, because it is right now a game of luck.

Hi there,

 

 

it seems to be related to external USB-devices in our case, if they do not have a own power supply.

If I use an USB-Hub with an own power supply the problem seems not to occur.

 

So how can this be fixed Lenovo?????

Hi there,

 

 

yeah....same here, I made several test runs yesterday. It is enough to set to high performance energy profile, brightness on max and the error occurs randomly. If I then connect an external USB-device the error more often occurs.

 

Lenovo needs to take care about this, we have got 2 T540p here with the same issues. They are not usable right now.

 

If there is no response, we will have to send them back in the next couple of days and buy different ones from a different company.

 

Best regards,

 

Marcus

Similar problem here. I think it's due to intermittent contact between the pins on the output connector of the ac power adapter and the power receptacle on the laptop.

 

With the power connector firmly plugged in at the back of the laptop, if I move the connector slightly from side to side, there are some positions where the slightest movement disconnects and reconnects the external supply. This is quite serious because often you need to be sure that external power is connected. For example, at the moment I can't rely on the battery being charged up if I leave the machine unattended. 

 

(I wonder why Lenovo left off the customary LED to indicate when AC power is connected? Without a lamp, it's quite difficult to trouble-shoot problems like this).

Hi,

 

I don't think so. The problem occurs for me even without touching the laptop. I also moved the connector but the power supply was stable.

I have the same problem. In my case it only occurs just before the laptop is fully charged (typically it begins when the battery is at about 96% charge and then happens some 8-10 times before it reaches 100%). I have seen no difference in moving the power connector around, but the 96% threshold is pretty constant.
