Mac Mini 2011 will not boot (no chime)

[g5amo]

Hi Guys

I'm new here, apologies ... a beg for help right out the blocks ...

My Mac Mini 2011 powers on ok, but there's no startup chime and no keyboard response. The only thing I've ever upgraded is RAM (supplied Crucial UK) but that's been working well for over a year.

I've tried swapping the memory modules around but no difference. I note one does produce the 3 bleeps of death, but the other 8GB stick does not and the system will still not boot. Have tried the usual PRAM/SMC resets and still no luck. I cannot locate my factory RAM (doh).

Anyone encountered the same? Could it be logic board battery?

Regarding the startup chime. Maybe the Mac-Mini's volume is muted or too low to hear.

Regarding the keyboard response. What sort of keyboard is this...wired or wireless?

- If wireless...are the batteries good? And if a blue-tooth keyboard...is it paired properly?
- If a wired keyboard. Have you tried a second (known working) keyboard?

Hi Nick

Thanks for replying. Wireless Apple keyboard and mouse.

The chime was working fine yesterday, this behaviour bizarrely started when the batteries in my magic mouse and bluetooth keyboard failed at the same time. I had to hold down to power button on the Mac Mini to shut it down. Once I'd re-charged my batteries, the Mac Mini now refuses to boot. Regards pairing, the keyboard led certainly flashes when I try to boot the Mac so I'm assuming (a total guess) the pairing is ok.

I'm at a bit of a loss. A couple of searches have suggested that complete failure of the logic board battery can cause this behaviour, so as I've had this 5 years since new - I've ordered the tools and battery from Amazon. If you or any other forum members have other suggestions though I'd be most grateful.

Alan.

Thanks Nick.

Unfortunately advice above (+ LBoard battery replacement) has had no effect on problem. Having had to strip down the Mini to bare metal for the battery replacement - all connectors can also be ruled out.

I am somewhat resigned to this being a logic board problem, very disappointing as I sunk a few quid into this with SS boot drive and dual core i7 from new. I'm in the UK and £500 for a new logic board is a bit sore.

In conspiracy zone after October 2016 announcement ... grrr

Oh well its a new Mac Mini for me. Mercifully ordered before eye-watering UK price hikes on Thursday - I love Apple kit but come on ...

Looks like a video chip failure on old machine, so will be getting repaired and its off to eBay.
