HDMI port does not awaken from sleep mode

drobe11 — Mon, 27 Jan 2014 01:09:03 GMT

I am running a dual-monitor setup on Windows 8 with an Intel HD 2500 graphics card (driver 10.18.10.3379). I run one monitor out of the VGA port and the other from the HDMI port.

All is well until the computer goes to sleep or I shut down, at which point only the VGA port will awaken (regardless of which of the two monitors is connected to it). If, however, I pull the VGA plug from the computer before awakening, the HDMI-connected monitor will turn on, and then I can plug in the VGA plug and get the dual-setup working.

It seems that the HDMI port will not turn on unless the GPU sees there is no monitor connected through the VGA. If that is the issue, is there any way to "force" the HDMI to life?

I am running a Levono H430, with a i5-3330 processor and 8GB of RAM.

Windows 8, 64 bit.

One monitor is a Dell ST24 and the other a Samsung SyncMaster 930b.

The only other things attached to the computer is a keyboard and mouse.

Thanks Sonny. One last question. Do you know if your system has the latest BIOS? It can be found here: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT073549 http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT073549
