Greetings people,

Proud to be owner of a Lenovo Z60m machine.

Recently i've change the original 512MB to 2 specific dimm's of 1GB each. Both Dimm's are specific to this machine.
Everything ok after the install : 2GB installed, computer now runs faster.

What happened afterwards is: the computer freezes under AC adapter power, whenever it displays any sort of complex or elaborate graphics such as: videos, HTML pages, program Logos, etc.

All this doesn't happen in Battery operation.

I have 2 batteries. One 6cell and another 9cell, both original and everything works OK.

What could be the problem?
I don't think there's any problema with the Dimm's since computer works fine in Battery mode.

Many thanks in advance
Pernalonga

Run Memtest86+ on your RAM and make sure your BIOS and other drivers are up-to-date from lenovo.

Hi there,

I haven't had the chance to test the memory yet. Though i've tryed once again, to insert the 1GB DIMM in order to get 2GB of RAM. Same problem, same freezing after doing it. In one of those crashes there was a BSOD where it was possible to see the file causing the mess: ati2dvag.dll in an infinite loop.

I've already done a search through the WEB and know this file is a very critical issue. My goal is to rollback the ATI driver to somewhere around version 5.3. Since i don't really use the notebook on hardware stressful games, it should be allright.

The thing now is : to find that ATI driver or IBM/ATI driver, presuming that there's any difference and that the second one is the most appropriate.

Any ideas are welcome !!

Regards
PernaLonga

Well just got 6.1 drivers and tryed 2GB in 2 1GB SO Dimms and the problem persists.
Next, i'll try the memory test.

Cheers people

May be worth updating the two power related system drivers in system update. I noticed similar problems with my Z61m with 2 DIMMs installed (and no problems with a single DIMM) and the updated power management drivers seemed to help.

Curious u mention it, I removed power management drivers and now i can't install them via "system Update". It installs but once the system is restarted, there's no Icon next to the System Tray Icons.

But wait a minute, you say "two power related system drivers in system update". What Drivers are those ??

Cheers

Problem solved (apparently)

With the help of this forum, searching on 2 or 3 main ideas i've been able to apparently solve the problem.

The main "keyword" was Underclocking which, by the way is a concept i never heard of.

Since trouble symptoms were display freezing and ati2dvag.dll error message (BSOD) - when using 2GB of (specific) RAM, i went through ATI Catalyst Control Centre's options (which i never did) to search for anything related with underclocking. This was one more "give it a try" where i already had done many things such as, removing Power manager drivers, Re-installing old VGA drivers, swapping several DIMM's in every sort of combination, re-instal XP OS - and none of this worked.

The following image got my attention, as i think both sliders (circle in red) are related to GPU clock perfomance when operating on battery or AC Adapter. By default: AC Adapter slider was in "Perfomance" side (pointed in green) so i put it to "Optimal battery life" in order to lower GPU clock Speed.

After this i re-installed 2GB (been using 1.5GB) and since then (24hours) it's been working ok

To double check it i put the slider back on the perfomance side again and the system went on crashing again.
So to me, although i still don't know if this only hides serious trouble with my VGA card or complete motherboard, it consistently solves the problem.

So far I didn't notice any perfomance damage but then again i'm no serious gamer at all.

1 Note: i'm using the latest in IBM System Update / ATI Driver and Catalyst Control Center as well as Kingston (Nayna chips) specific RAM for Z60m.

____

Along this time i've read other people's testymonials on similar problems and few, very few solutions. Give this one a try. Maybe it will also work with u people

Many thanks

Hi there,

This is to let you know that i've ended up sending my Z60 to Warranty. The notebook was working but not at top perfomance.

Just received it today. It has a new Motherboard and is working in Full Perfomance mode (ATI CCC Stuff etc)

This was all due to a Memory Dimm not 100% compatible which somehow degraded the Motherboard.

IBM is not kidding, oh no: when they tell us to use only 101%specified Memory Dimms. In fact other brands require the same.

Best Wishes

I had the same problem but I could identify the source of all evil. With the original RAM in the 1st socket memtest86+ reported no errors.

In the 2nd socket it reported no errors either BUT! it displayed an incorrect RAM Timing 3-2-2-0 (should have been 4-4-4-12 like in the 1st socket)

Result: new systemboard (again)

'till now everything seems ok.
