Hi,

i just got my acer 5750 (second one after getting my first one back in january due to sandy bridge issue...)

BUT now i have the same problem again?

The laptop is manufactured in 03/2011 but all diagnostics tools like cpu-z or aida64 show me that it still has the b2-stepping chipset from intel?

Is this a joke or is acer seriouskly delivering still buggy mainboards? I'm quite upset... Though the check on the acer homepage shows me that theres no need for rpairm but i'd rather belive those tools than acer's webpage...


can anybody look up and see if he/she has b3-stepping( new bugfree) or has the buggy b2-stepping, too?

by using cpu-z for example, simple tool:
http://www.cpuid.com/softwares/cpu-z.html

no need to install just download the zip archive on the right.

then start and tell me please what is said under "mainboard" and "cpu"

mine is looking like that:



It shouldn't be B2 in "mainboard"(in the red circle) i think?

edit: wanted to add.

I think acer doesn't change the mainboards really, they may change the ports of the hdd, mine is connected to th #0-port which shouldn't be affected by the bug. So it would have no effect for those woh still have b2 stepping instead of b3.???

ok, well port0=HDD, port2=DVDdrive

i got contact with some other buyers, having same issue, i hope acer is not playing a game with the customers selling us buggy hardware hoping that after the warranty time we cant do anything...

strange: On the acer supporrt webpage it says thers no need for service...

but would be really interesting what stepping you have, as your motherboard was indeed changed

ok, i got response by acer directly, they only checked my serialnumber and tried to convince me that i already have the new chipset built in...

If thats true i'm fine, if not i'll show them that response if anything happens to my optical drive

@GooD_Day: don't want to urge you but would be very nice of you when you have time to check your stepping

btw: nice forum here.

greets

Saved my day

I usually have no luck in electronic goods every time theres a problem, but as your motherboard was changed and still shows b2-stepping, i think that everything should be fine then. Thx.
