Acer TImeline U boot issue

post #1 of 8
Thread Starter 
Here is my laptop: http://www.newegg.com/Product/Product.aspx?Item=N82E16834215392

Basically it does this randomly at times. I will go to turn it on and it will start to boot the keyboard will light up, but then after 1 second it turns itself right back off. I have found simply clearing the cmos by taking out the battery will fix it temporarily, but it will do it a gain some time later on.

It does this:

Got any ideas on how to fix it?

I've done the following:
Uninstalled the MSata drive, upgraded my HDD to a Samsung 830,
popped in 8GB of RAM.
Unplugged the cmos battery and the main battery and held the power button down for 30 seconds to reset the BIOS.
Tried reflashing the BIOS (v1.12)

I have the latest BIOS




I am thinking to go to an older bios rev, but IDK where to get one. i had no issues with v1.02

Have you tried running it without the battery in and seeing it it does it. I think theres a short either in the adapter or battery.

Well the thing is that it does it randomly and the only times I use it are when I don't have the charger. lol Also, I have to take it apart to disconnect the battery. (not hard, just annoying as that is 16 screws to undo)

Any other way to check for a short rather than just taking out the battery and using it on the charger only and hoping to have the issue appear or not appear during that period?

I just downgraded to BIOS v1.05 as well...i may try 1.02 if I find it.

Well if you have a multimeter you could read the battery

Well, I disconnected the battery and after turning it off and on a few times with just the power cord plugged in it gave me boot issues, I actually couldn't boot until I opened it up and cleared CMOS. frown.gif

So the battery is now ruled out. I think the mobo is failing or at least the gfx for it. Because after I was able to boot it said starting windows and froze and the whole screen was glitched out with blue square outlines.

Well you could bake the motherboard if it isnt covered by warranty. Be careful to not melt the cpu socket.
