Odasha Posted August 8, 2017 Share Posted August 8, 2017 (edited) Hi! First of all, cool forum. You lot seem extraordinarily knowledgeable. So my mashup laptop is giving me grief. It'll power on, boot and function as normal except for an endless 2,5s interval high frequency beeping and lock buttons flashing following max speed fans. This all happens in bios, whilst idle in Windows including safe mode and in any other circumstance and shuts the computer off after a minute or so. Dgpu is working correctly according to device manager. I cannot see an on-board gpu in device manager but disabling Dgpu in device manager does not cause the screen to disappear. Rebooting in that state however means pitch black. Bios is ami Things I've tried: Reseat ram Test my ram in other laptop Test other ram in mine Reseat gpu Repaste heatsink for gpu and cpu De_dust innards Change graphics drivers Reseat hdd, ssd Remove hdd Remove ssd Remove gpu Remove fans Reset cmos Boot without charger Boot without battery Cpr Removing keyboard Changing cpu min load in power settings Disabling pretty much everything in bios Kissing and begging Computer does not get hot or even warm to the touch, many programs suggest temperature of gpu and cpu are around 45c - 55c, seems accurate with hand over heatsink. I can prolong my sessions and avoid shutdown by putting it to sleep and waking it repeatedly. For some odd reason after trying my friend's ram (which worked), swapping back to mine one by one also seemed to work, for no reason. Fast forward 6 months, same problem, borrow the same ram, doesn't work this time, until I get home and boot just for the heck of it. Now it is working half the time, changing power settings also seem to dictate whether the pc will beep, but only temporarily. Tested more ram and it seems as if it was never even a fix, just coincidence. Tl;Dr Beep flash shutdown Clevo sager eurocom Gtx 980m i7 4810mq e/I am at the end of my wits for what I dare do without guidance. Any input is greatly appreciated!

H658tu Posted August 9, 2017 Share Posted August 9, 2017 Don't recall the exact number, but ~20x beep means no rpm signal from the fans is reported to the system, causing a (v)bios/ec-initiated precautionary shutdown. The cause can be due to a number of items, the gpu being the primary suspect. This system doesn't have the iGPU part hooked up, so it cannot run without the dGPU. See if you can borrow one or buy a cheap, low-end used MXM and try to run that. Quote Link to comment Share on other sites More sharing options...
Poprostujakub Posted August 18, 2017 Share Posted August 18, 2017 Yes, it sounds like bad connection of fan yellow wire. Quote Link to comment Share on other sites More sharing options...

Nothing changed. Speedfan shows millions of rpm from cpu fan and doesn't not show a gpu fan. Took out gpu fan and tested. Cpu fan now showing realistic 6-7k rpm. Took out cpu fan and put it in gpu fan connector, again millions of rpm from cpu fan while there isn't actually a fan in the cpu fan slot. No gpu fan records. Took out cpu fan and put gpu fan in cpu fan slot. Cpu fan records of 40k+ rpm, still more realistic than the millions. I reinserted both connectors many times to get rid of dust and such. Gpu fan female connectors plastic casing is a bit damaged from all the insertions and such. This is starting to look like a fan issue to me, or atleast Fan related.

H658tu Posted September 26, 2017 Share Posted September 26, 2017 Yes, that or the EC is corrupt. A full bios + ec flash would solve that, something the reset alone will not accomplish. Quote Link to comment Share on other sites More sharing options...
