I went to plug in my Toshiba laptop today and it essentially shut down. I waited a few minutes and then turned it back on. When I dud it gave me some weird screen asking me to confirm the time and date which was showing as 2015. So I shut it down and waited for a bit. When I turned it back on everything ran normally. A few hours later while on the computer it literally just shut completely down with no earning. Worse, I can't even turn it on now. And its not even showing that power light being on even though light on the cord itself is on.

This sounds like the CMOS battery has died, one of the first symptoms being the time and date going wrong. Most, but not all, computers will run with a dead CMOS battery but you are required to set the correct date and time before thay will boot. This is probably the screen you saw. I have only run into one computer which would not even boot until I had replaced the battery and that was an e-machine laptop.


The most common battery used is a CR 2032 which are pretty cheap, you certainly won't need an overdraft to buy one, and Toshiba are generally fairly good at making these accessible. These batteries are round, silver coloured and about 2 cm wide. To find out how to change it go on to YouTube and enter 'Make and model' + 'CMOS' into the search bar. If that doesn't produce a result enter 'Make and model' + 'Teardown'. This will supply more information than hopefully you will ever need but will include the CMOS battery.


If you had quoted the make and model of your laptop I could have found you a link to the relevant video. This is why this information is important and useful !

I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !

Welcome to Bleeping Computer.


While I'll second the CMOS battery as an issue.  Laptops are a whole different animal from desktops.  Most of the HP CMOS batteries I've seen have lead soldered to the batter and they are connected to the system board.


This will sound stupid, but if it works it isn't stupid.


I suggest removing AC power and the battery and then hold down the power button for 30 seconds and then put it all back together and try again.

Did you say Toshiba laptop?  Did you get the extra battery slice?  I did.  I sure did.  I loved that two battery action until..... everything did not work anymore.  I blamed it on hacking the ACPI stack to turn off the main ac adapter feed.  I will never buy the slice battery ever again.  NEVER for another laptop that is Dell.  You need to attach it to the alternate AC power feed which is hidden.  It is available with the docking station.  There is no way to get it to redirect back to the laptop and you are stuck with the docking station to feed power to it.
(yeah I know you bought that extra slice battery... yeah...)
