Hi,

I have the above model that keeps shutting down within 15 seconds of it
loading the windows desktop (win98).

It also keeps flashing the LED nearest the number 1 on the battery
indicator. This notebook doesn't appear to want to run of the battery at
all (it doesn't seem to hold a charge).

The shutting down problem is still happening when plugged into the mains.
It doesn't do it if it's booted in safe mode though.

Any ideas would be greatly appreciated.

Thomas.

These old F series sony laptops are also known to have motherboard issues that cause it to shut off instead of sleep.

Old Sony laptops do this when the battery is dead, or the charging system is below required voltage. A battery with a dead cell (which this sounds like) can damage your external PSU and internal battery/power regulator circuit. Remove the battery (shut down and disconnect PSU first). You can run the laptop forever, without the battery, if you cannot find a battery replacement, or do not like the cost. Obviously, though, the laptop will not run at all without the AC/PSU connected when the battery is removed.
