Driver is missing-how do I find out the error code

I have a Lenovo Y510 Laptop that has been upgraded to Win 7 64 bit. Was initially a Vista 32 bit so had to have memory added, etc. Nothing notable except last time the hinges were changed (these laptops have hinges that do not last long) it was sent back and shortly afterward the mouse pad on the machine quit working. I get an error code of 28 on some device I will paste what it says.

Secondly, the DVD has stopped working.

1. Microsoft ACPI -Compliant Embedded Controller (off the Other Devices -Intel ICH8M LPC Interface Controller -2815) says Unknown Device when I go to look at properties it says "The drivers for this software are not installed. Error Code 28." I tried to locate drivers and it could not locate them.

2. Secondly on the Mice and other pointing devices -Microsoft PS/2 Mouse This device is not present, is not working properly, or does not have all its drivers installed. (Code 24) but it says it has a driver which is Windows\System32\DRIVERS\i8042prt.sys or mouclass.sys. Any ideas?

I am not worried about the DVD not working as I am just using an external one. I also bought a USB driven mouse since I could not get it working.

Did you install the driver

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/7kss73ww.exe

After installing the driver do you see base system in device manager.

Check device manager. do you see any yellow exclamation marks. If you see them make a list. Double click on the yellow exclamation mark -click details- select hardware ids- post the ven and dev ids.

If possible post the screenshot of device manager.

Regarding dvd just delete upper filter and lower filter

jlfcpaAuthor Commented:
Yes, but what is the base system and what is it for? I still have no mousepad, I have the lenovo discs that came with it but they are 32 bit and they will not work with this 64 bit.

also i never found out what happened to the internal cd/dvd, but I have seen many write-ups about this optiarc dvd and never have found out why it will not work, much less why the computer does not even know it is there.

Base system was for you memory card reader hardware.

Right click on the dvd driver from device manager and uninstall it. Then restart the computer.

Another is Microsoft mouse. So select your model number from this link and install the software.
