Samsung 2012 Series 7 Chronos (NP700Z3, NP700Z4 & NP700Z5 series) Owners Lounge

[spincel]

Hello all,

So I tried a couple of things: I tried re-installing Windows 7 Professional as an update, which didn't fix the Sleep mode problem, and I tried doing a clean install of Professional as an OEM purchase, which also did not work.

It was at this point that I restored the laptop back to its factory/ delivered settings (it came with Windows Home Premium installed), AND SLEEP MODE STILL DIDN'T WORK.

So it cannot be a problem with the upgrade since Sleep mode won't even work with the laptop's original settings, right? My event log is showing errors and warnings about an ACPI driver and Kernel power, both of which are controlled by drivers that I have no control over.

Any suggestions? It is starting to look like my only option is to return the laptop...

It is related to Bios Setting and Bios Firmware. Those Kernel-Power errors have something to do with either Bios or mainboard. If you not on the latest bios, try to upgrade it to see if it's fixed or not. If not, then just call Samsung and let them service. They might have to change the whole board or even trade you a new laptop as well. I haven't seen any issue with sleep mode with different brands, but my main desktop once had Kernel errors and I had to exchange for a new board.

The mainboard has to be changed IIRC.

Alright thanks guys. You've all been very helpful. I'm sending the laptop back tomorrow. Once my refund is credited back to my account I plan on ordering another 700Z5A, and hopefully never run into this problem again...

Nope. With the lastest graphic software update, the issue has been fixed. Been using it for nearly 3 weeks and I don't have much issue with it right now. Everything is stable at least until now .

Hi spincel, thanks for the info!

Hi, I've just heard about another problem with this laptop. On some owner review sites people are complaining about wifi problems, i.e. not staying connected or slow connection. Is anybody here having this problem? Thanks!

Well in my opinion it is because of the aluminum casing and poor antenna placement. If you were to get the Intel wifi chip it might improve but it will really vary.
But problems like no connection or slow connection I got none.
However you will notice internet might be a slower then normal depending on where u are sitting.

In addition, as someone pointed out in another thread, if you check the advanced options for the power saver and balanced power schemes, there are options to boost the Wifi signal. This is maxed by default in the High Performance scheme, as you would expect.

I don't have any problems with poor signal, but I do get occasional dropped connections, which are fixed simply by disabling, then re-enabling the adapter. I have the Intel one.

This is most likely the biggest issue with Wifi on this laptop. People are using it on the default setting while on battery, and then the option is set to "Maximum Power Saving" which leads to very poor performance and range.

I never had an issue with the Wifi on this laptop. (I have the original Broadcom)
