My laptop one day refused to power on, no lights, nothing, it was like the electric had been cut. I normally use it plugged into the electric without the battery and use it with battery occasionally, tried it with battery in, still nothing. Got on my other comp and a search for an answer came up with this,
"Remove the power supply, and then take out the battery. Hold down the power button for 15 to 30 seconds...then put the battery back in and plug the power supply in."
I pulled the power lead and batt from the laptop did the above, still no go, I then de-powered the brick for a few mins, put everything back and it works.
Anyone know why that is and should I totally de-power occasionally?

Hi greebal, The power button 'trick' essentially releases any stored charge (ESD) allowing for the system to boot normally without a conflict on start up. You don't need need to do it often at all, only when an issue such as this arises. (unfortunately it doesn't always work) Think of it as a refresh of the electrical system if you see what I mean. At least this is how I see it, others may be able to explain things easier/better but my mind works in a weird way

Whilst what you both have written should work OK, what I tend to do is disconnect the power supply, remove the battery, and leave for 30 minutes.
Forgot to say, unplug everything else too. USB drives, mouse, et al.

Thanks Guilty,
I forgot to add that my system time and date used to often be wrong after a power on but has been stable since.

Lighthouse,
Can I ask why 30 minutes?

Time and Date being out of wack sometimes is due to CMOS battery going bad but only if it constantly causes the same issue.

Time and date prob, means a nearly dead CMOS battery.

cos 30 minutes will totally discharge the capacitors in your laptop. OK, probably 10 will do, but people get impatient, and try too soon. Thus I always say 30 minutes, go make coffee, have a shower, water the dog, walk the garden, whatever:)

Thanks Lighthouse, I will remember that. Regarding a CMOS battery I was thinking same as you but a nightmare for me to replace it is on the bottom 2 pics of 2-20 here

I've also seen this which is my model. Nightmare for me but how long do/should CMOS batteries last? This thing is only about 4yrs old.

Well there's no defining answer to that but an average is probably around 6yrs but varies from MOBO to MOBO. (motherboard) If that's your model then you may just be able to access the CMOS from under the back panel.

Will bear that in mind, for now as said earlier the time/date is OK, I will see how it goes. Many thanks for your input.

Averages for most modern laptops is 5-7 years. Asus, being very reliable computers last even longer. I found on a previous machine I had (a toshiba) the time and date would randomly change. I assumed an MS update may have caused this. In that case, I reset the time and date in the BIOS(!) and the problem never came back.

Yes I have that video, I did link to it earlier. Not going for the strip down yet as the clock is behaving so far, hopefully it will be OK. Interesting for me is how easy it is to remove the DVD drive. My DVD drive does not work anymore but I'm not bothered because I have another machine with DVD and believe I can use that slot for a HDD, the machine came with 2x 500GB HDD's and I replaced one with an SSD so my thinking is to use the removed HDD in the DVD slot. Easy or a lot of messing? Appreciate any thoughts.
