Windows 10: Waking up after prolonged period of time brings up Bios POST

This started happening within the last couple of weeks. Basically, sometimes when I put my computer to sleep and come back after a prolonged period of time, when I wake it back up it seems like the computer is rebooting - my BIOS Post screen comes up, and the system takes a little time to load. However, when I log in everything is exactly how it was when I put the computer to sleep (all my applications are open and in the same place, etc.)

If I put my computer to sleep and immediately wake it up, this does not happen.

This is a problem, though, because I dual boot my system in to both Windows 10 and Linux, and the Linux is the default boot option. So after my POST screen, if I'm not there to select the Windows boot option the system boots up in to my Linux install.

I haven't installed anything new on my system, although I think Windows pushed an update recently.

There are no problems when I'm using the system (i.e. it never just randomly restarts while I'm using it or anything like that).

Any ideas? Thanks

:)

 

Windows Hello

Hi Omair,

If you're going to let your laptop sleep for a prolonged period of time, why not shut it down? Sometimes, any other PCs experience issues upon waking up from a long sleep because while your PC sleeps, electricity still flows inside it, causing warmth to
PC components which could lead to some minor problems. We always recommend shutting down PCs when it is unused for energy conservation and to prolong the PC's life. Kindly turn your PC off if you're not going to use it to prevent some major issues which could
happen. Windows 10 offers fast start up so turning it back on won't be a problem.

Should you have more concerns, feel free to post.

Regards.

 

Windows 10 BSOD upon waking from sleep

Hello, I have been having a persistent problem where if I leave my system in sleep mode for any prolonged period of time (5+hours) my system will Blue Screen upon waking up, can anyone identify the problem and suggest any solutions, here is the link to most

Thank you in advance.

 

If the OEM Logo comes up, sounds like your CMOS battery is going bad. Change out the battery. Also make sure your bios is up to date.

 

Interesting. I'll replace the battery and see if the behavior changes. Mobo isn't that old (only maybe about 2 yrs), but I guess who knows about the condition of the battery when I got it.

 

The CMOS battery's can go bad at any point. If it came with one installed, the manufacturers buy the batteries in large lots and they are always going to be from the cheapest manufacturer.

The first thing when you start getting the Bios Logo, is to reset the Cmos and replace the battery to rule that out. Also make sure that the Fast Boot is enabled, which can get changed if you were trying to troubleshoot a problem sometime back.

 

Changed out battery and updated BIOS - so far everything seems to be back to working normally. Will give it another day or two and if the problem still seems resolved I'll marked this has solved.

When the CMOS batter goes bad, though, isn't one of the tell-tale signs that the computer starts to lose time? Or does that only sometimes happen? (asking out of curiosity)

thanks *Smile

 

There is no way of telling. Sometimes you will get alerts that the clock is off if you are using say Linux or Windows 7. Now you do not even get those warning signs with 10. It could have been anything like a slight static spark when you went to power on your computer, to just something bad that is starting to show signs on the motherboard, but you will not know.

I would still go through and clean out any and all dust, get a magnifyng class and make sure that nothing may be contacting the ground plane, that the motherboard is not touching the case to the ground plane on the motherboard, all cables are where they need to be and that the battery is firmly in place.

The other is if you have it in a surge strip, just even powering it off for a week, something could cause the battery to drain quicker than it should.

I would say to figure maybe 18 to 24 months change out the battery to be on the safe side.
