This concerns a Fujitsu Lifebook NH751, about 11 years old and running Windows 7.So far it's been super reliable and I can't afford to change just at the moment, although I know it must be running on borrowed time.
A few weeks ago, for the first time, as soon as I pressed the switch to power up and the Fujtisu splash screen appeared, the laptop emitted a single short beep. This is now happening randomly - perhaps something like 1 in 12 startups. Windows loads normally without any obvious glitches. Plus, the machine is running perfectly and there's no evidence of anything wrong with the "vitals". I had look in Event Viewer on the off chance it might show something amiss- but nothing abnormal at all.
I'm wondering whether the beep indicates a DRAM refresh failure, but if so can't understand why the machine boots normally. It's a Phoenix Bios and I thought that a single beep simply meant that POST has been completed successfully - but that doesn't explain why the sound has just started "appearing".
Grateful for any ideas about this.
