you power drain it by unscreewing the battery, then removing it and after this open the notebook and hold the power button for about 20 - 30 seconds.

is there a service manual for this notebook on the website where you ordered the system?

 

Next step if you can't fixing the machine. Maybe a computer shop can try your processor in an other computer.

 

Yeap changing the ram to another slot is usually enough when you are OCing the RAM and set bad values, the system would read new ram values and would reset yours (i think it´s something like that), does not seem to be the case here. A full reset like what you just did by removing batteries would also trigger new NVRAM readings, you would even get a message telling you that on your first boot, something cool about these new generations, so honestly i´m out of ideas.

 

Remove including the mobo battery? Also it did not come with a disassembly guide. It came with a manual though but its pretty useless

 

There´s a big difference between a user manual and a service/technical manual.
But you don´t need a manual to remove both batteries, you already did that right?
I think what you need now is just new hardware to test the system, another cpu would be great.

 

Oh boy. That said i think i have to get a new 6700k. Hope the new one will work like a charm. Ill just use a creditcard and pay it 6months. I am really sad right now

 

nah only remove the main battery. then press the power button for like half a minute.

nope, it's called service manual (where stuff like changing gpu, removing cpu etc. is documented). i just checked the website where mine is from but the service manual is only offered in a german version. maybe someone else on here can help with that.

 

Dont go buying a new CPU without being sure the one you have is broken. Go to a store and ask to try another i7 on your system or ask them to try yours.

 

i was only refering to the service manual for the ram reseeating. but i forgot about the already done cmos clr and nvram reset. ;-)

 

Ill be calling stores tomorrow hope they have a working system where i can try my cpu in. Now what if the cpu works fine on another system? Then the prob is my whole system?

 

Then put in a no delided cpu and use your warranty

 

Yeah i could do that but i will be out of a system til august! Or i could send it in to helix our local reseller but i have to pay for whatever the damage/d part is. I am praying its a bad cpu! I can always get a newone tomorrow and pay it in 6 or 12 mos so that i wont feel it

 

Take a trip to a local computer store tomorrow and they can test your cpu. They can also probably test your system with own cpu too. To rule out all possible problems with your machine.

 

Will do. Thanks for the advise!

 

Ok, if you have the dm, I didn't find the service manual. As long as you don't have the p775dm, . This will be very similar:
https://repo.palkeo.com/clevo-mirror/P770ZM/

Meanwhile, I know the p870dm had more issues resetting the nvram than the zm series. Review mr. Fox's statements in the p870dm thread while working on the firmware!

Maybe @jpsm should at least try resetting NVRAM one more time. Worth a try. Do it by the book.

 

Thanks will try it again. So good news i found a bnew 6700k at 15800php or 338 usd cheaper than amazon price at 351usd but catch is i have to pay full cash upfront.

 

Will do quite a challenge to do bec i only have access to a ipad and 6splus rofl anyway ill try to download it

 

Haha, good that you figured it out. I usually tend to use a ball point pen to push it out.

I have a feeling that you might have pushed the blade in too far and hit the die. Also did you use a double sided thin blade or the thick single sided one? The double sided ones are very risky because if you are not careful and bend the edge you will cut into the pcb. You need to use 1 blade on each side to cut in straight and slightly angled up wards from the PCB (if using the double sided blade).

You just need to take the keyboard out, and then remove the CMOS battery for a few seconds.

 

I am looking at the service manual now, i cant find anything on resetting vram, only bios installation etc.

 

Remove cmos battery instructions are there, but don't go to the depth Fox discussed for the troublesome reset, including moving ram, cmos and other battery out, unplugged, etc. It may act funky while trying to make it **** the bed and reset. Please search that thread.

Remove the keyboard and change the ram to another slot?

 

Do it the whole way. Pull out the main battery, then power drain. Push in power button 1 min. Take out cmos battery. Wait a few second and put it back. Put in main battery and power on your computer. Wait and see what happen.

 

870dm forum? Is it possible i shorted my system by not removing the battery?

 

Always remove main battery if you take out hardware. You can fry your hardware without doing this!!

 

bent mthrbrd cpu socket pins can easily lead to a no-boot situation. Bent pins occur when the cpu is incorrectly inserted, or 'dropped' in off target. If all else fails, then inspect your pins at some point. Not that you need these, but here a visual & here are random 'pin straightening' vids

_____________________​

Listen brother. If you reach the point you check your cpu pins, if they all look ok from every angle, take the utmost in caution, delicately reinsert the cpu & clamp her down. Do not bend/damage your pins, simply because you checked for bent/damaged pins 2minutes earlier ...

 

Check for bent pins. I did that to my zm. Touching the cpu with power still connected, if the wrong pin touches the cpu underside, it can fry it. A cut in the pcb can cause a short even if just exposed. Covering with a sealant can help, if it occurs, but the short could mean damage is done. If clu got on a cut, it can short. I could write a book on possibilities that I might not see from photos.having said this I've gotten lucky removing ram and cpus forgetting to energy drain, although others have not...

Thank you for this. I'll have to remember that for my p170hm!

Yeah..., better be safe than sorry. And ask others if you trying something you never have done before.

Edit: @Thumper_23 If you bothered to read the release notes for XTU, you have found out this long time before

 

NONO, there is a small battery under it, take that out for a few seconds and put it back in. That is what we call a NVRAM/CMOS reset.

Also as @Papusan mentioned, always good practice to remove the battery. But i rarely ever do it.

 

Is that different from the battery i removed on the underside of the laptop? Its also a circle shaped thing that pops out its on the left side

 

Not on the zm and dm models p7xx... It's on the cpu side, not under the keyboard on those

Yeap, thats the CMOS battery. Removing for a few seconds resets the CMOS/NVRAM. Basically a BIOS reset.
Keep in mind the first boot after putting that battery back in will take longer than usual.

 

Ahh my bad then, just checked his signature. @jpsm its next to the CPU it seems.

 

The regular battery must be removed as well as the ac adapter. All electricity must be removed from the system to force the reset.

You have to much money

Different machines have the cmos battery different places on the motherboard. Cmos battery is as you can see like a coin in your image.

 

I did not mean to be critical / rude

Edit: @bloodhawk Yeah..., it's enough to only take out the battery. But if you have trouble it isn't to much work to take out the main battery and make a fully power drain.

 

Not really, i have done this without taking out the main battery at least 4 times now. I think even Mr. Fox posted about this once.

 

I'm trying to also reset the ec, not just the bios. It is to reset the whole system!

Thanks for the help everyone even though i wasnt able to solve the problem. Would love to thank each one of you but could not do it bec i am on tapatalk right now and apparently cant tag people unless i input the name perfectly lol. Will keep everyone posted on my situation.

 

Weird, i actually did it last week after trying to push my RAM to 1T and removing the battery for 5 seconds, re-setted everything. The NVRAM gets reset and i think that works for the EC as well. I might be wrong so feel free to correct me.

 

Too much trouble bruh, soo many screws! Its like taking a horny Papusan out of vaccum cleaners.

 

The 700 series the battery is held by a simple clip, not screws like the 800 series! Also, how prema says unplug after ec/bios flash, that is to reset the ec, not the bios

Yeah its easy for you guys.
But what does the EC reset do exactly?

 

Got the DDR3-2133 running nicely at 2400 using manual settings in the @Prema BIOS.

 

Yeah surprisingly my el cheapo Adamanta (?) modules run at 2400Mhz CL14 perfectly. But they cant do a command rate of 1 at anything over 1866Mhz for some reason. What brand are your modules? And do they have Hynix or Samsung chips? I have seen the Samsung chips be rather over-clock friendly.

 

I have to wait for next month to test which timing is causing a little issue at 2400. Didn't have time to fully go through, but one dimm is throwing up flags in the same range every time on the second or third pass on test 7 of memtest86+ parallel with 11-13-13-27-228 timings. But I knew I couldn't test for perfect stability until after this project anyways. (Passes TM5)

Also, if you have a spare hard drive and time, benchmark the difference of uefi and csm/legacy. I think I went with uefi/gpt because of better scores, but cannot remember to save my life!

Either way, looking very nice!!!

These are the el cheapo G.SKILL Ripjaws DDR3L-2133 single rank sticks I reviewed here back in 2014:
All Memory is Not Created Equal - HyperX 2133 CL12 versus Ripjaws 2133 CL11 versus Vengeance 2133 CL11

I had the same model of SO-DIMM running at 2400 in the Panther, but the XMP profile that worked with the Panther for 2400 quad channel will not boot in the P750ZM.

 

That is what, in part, influenced my purchase of hyperx this round! Gotta admit, loving the scores and speeds with them!

Even lower end modules have the chance of winning the lottery it's especially satisfying when they do
