it is hard to say without knowing what the actual device that reported the problem was. My wife's 7 year old dell laptop reported a similar error and i could never get it to not report the error. In my case it was some mouse pad built into the laptop that was the source. never did get a fix and it would generate a lot of these logs (sometimes 3 each minute)
never did find anything that seemed to be wrong. In my case they were correctable errors that happened since the day we got the laptop.
in your case you might update the bios if it related to sleep functions and you really want to get rid of the log entry. Microsoft windows update increased the low power states to sleep in a deeper sleep state to save more power. Lots of people have devices that do not handle these correctly. Most will require bios updates of the machine or firmware updates some vendors provide driver updates but really are just disable the lower sleep states rather than fix the problem.
it would still be a hardware error like a checksum error during communication between devices but one that the system was able to correct. you might be able to find out what intel device ID= 7aba refers to by looking at all of the entries in window control panel device manager,
that are for intel devices.
note: when I query microsoft update catalog for 7aba
I do get a list of updates for intel other hardware devices:
(does not tell me what the device is, just the update file)
here is my query:
Microsoft Update Catalog
when I look at the docs for the catalog
device 7aba= Intel(R) PCI Express Root Port #4
now you would need to find go to device manager and find out what is connected to port 4
I guess you could just try the update catalog from that matches your windows version. download the catalog, uncompress it to your hard drive, then find the entry in device manager, right mouse click to update the driver then tell it to pick the driver you downloaded rather than search for a driver and see if your error goes away with the update. otherwise you have to find out what is on that port and update its firmware or the bios and hope there was a fix related to your log entry.
