Vague offer of laptop diagnosis. If you're not in a hurry.
It's not going anywhere so if you have any ideas then they'd be much appreciated.
Here's what I can tell you:
It's an acer extensa 5630ez, about 18 months old
It came with Vista and has been running windows 7 for about a year.
It's my main pc here, so I treat it more like a desktop (at a rough guess it's been running constantly for about a month), I did recently wonder if that might be a bad thing, but it's shown no signs of any problems.
I got a windows update prompt yesterday morning and decided it could probably do with a reboot, I just told it to install the important updates.
It finished and nagged me to reboot for a bit while I was saving everything, when I did let it reboot, I had to force close as "something" was still running (nothing was in the list though).
It went through part of the update installation, but after a while everything was black (I don't remember how long a while was).
I powered off, then back on and nothing happens, no post screen comes up.
To be clear, the power light comes on and stays on, the dvd drive makes a noise, the hard drive activity light comes on for about a second, as does the fan. If the battery is in, the charging light is on, and and there is a beep from the speaker when I insert or remove the power cable.
Currently there is a few seconds worth of activity from the fan every few minutes, but neither drive is connected so I don't know if they would be doing anything.
Also, the usb stick that is plugged in is lit up indicating there is usb power (it's not flashing though), if I reboot, this light remains off (apart from a flicker at power on) unless I switch to a different charger, then it will remain lit for the first power on only.
I have tried the following:
powering on with just battery, just power supply and both.
Removing the easily accessible components (hard drive, dvd drive, ram, wireless card)
clearing the bios by removing battery and pay and holding the power button for 30 seconds (the Internet is a bit vague on this with some people suggesting 60 seconds)
connecting to a second monitor to see if it displayed anything (it didn't)
creating an emergency bios recovery disk (well, flash drive) and trying to trigger it by holding fn+escesc when powering on (this is supposed to make the power light flash, but I'm having no luck. I did have the power light flashing at me yesterday, but I don't think I did anything special and I didn't know what it meant at the time.
If it was a desktop I'd have probably gone motherboard shopping by now.
Sorry if that's terrible to try and read, but it was a real bitch to type on my phone.
Any ideas will be very welcome.
