The Z465 notebook hangs up when the lid is closed

2010-11-07, 19:52 PM

Hello everyone!

The problem comes out from the integrated 'Mobility Radeon 5470' graphics card. When the graphics driver is installed and you close the notebook lid while the notebook is on the system hangs up (freezes up). It happens with any mod that is set for a closed lid — whenever it's 'Do nothing', 'Stand by' or 'Shut down'. The system freezes up in any case.

When the graphics driver is uninstalled the closed lid makes the notebook go in stand by and shut down with no problem.

What to do?!

 

Regards

issue persists while using wireless connection? if yes, disable wireless save power option.

try to re-install power manager and check event logs for errors. ( right click my computer > manage > event logs )

It hangs up even without any wireless connection.
No errors marked at all.

have you tried to perform clean windows installation?

before that, do not forget to check if issue persists on safe mode.

In safe mode everything works fine. It's video drivers as I've already said. Installation was quite clean.

it seems one of the application causes that issue ( or driver )

i suggest you to un-instal all the drivers and install them one by one ( after installing one of them, check if issue persists, otherwise install other one )

also, try to update drivers from lenovo download page.

edit: typo

There's the only graphics driver available for now. I'm waiting for it to be updated. But please remember what I've said: this issue is caused by the graphics driver as nothing disturbs when it's uninstalled.
