I have a Sony Vaio VGN-FE28B Laptop. I'm fixing it for a friend - just doing a simple format, re-install OS & software etc.
I wiped the hard drive, re-installed Windows XP and then went through installing the drivers, AV and other software. Everything working OK. Nice
I now cannot get the thing to boot up! This is what happens EVERY time I turn it on:
- A couple of clicks and whirrs as if it's about to start up, but then all goes quiet
- No display
- Will not boot
- CAPS LOCK, SCROLL LOCK, NUM LOCK lights all ON
I have tried starting it with the following configurations and the results are all exactly the same as above:
- Battery and AC Adaptor
- Just Battery
- Just AC Adaptor
I have tried booting it in the above various power/battery configuratons with NO RAM and NO Hard Drive attached; still the same
I have tried leaving it running in this state and letting the battery run completely flat and then tried on AC - no joy.
I've tried various things I've read elsewhere such as leaving battery and AC disconnected for a few mins, pressing the power button to discharge the system, then connecting AC back up - but still no luck.
One thing I did notice is that after a while of leaving it in this non-booting state the power light and battery light on the front lip of the case and the light on the actual power button itself all start to flash at the same time. (This could be because the battery is flat?)
When I have the battery connected the battery light on the front of the case flashes; flash-flash--pause--flash-flash--pause-- etc. (This could be standard AC charging flash?)
Does anybody have any ideas about this? It's driving me mad!
I did change the Power Options after I reinstalled the OS:
I set the Turn Of Monitor/Hard Disks and System Standby times to longer periods.
Set the Low Battery/Critical Battery Alarm to lower percentages before it warns me.
And changed the activity of what it does when I close the lid or press the power button.
I set these back to defaults... and guess what?
It works It boots up with the battery connected!
I would NEVER have expected that an OS power management option would have ANY impact on a machines ability to BOOT/POST.....
All part of the fun of fixing computers ay? Hey man - thanks very much for your help. I would never have guessed that it was an OS option! I'm glad to leave the power settings as-is if it means I can use the battery!
While I have someone here who is so willing and able.... On an completely unrelated matter - my own personal PC...
You know that a USB device/cable will only connect a certain way round right?
If I 'touch' a USB device the wrong way round to the front USB hub on my desktop PC it cuts out, powers off instantly.... strange eh?
