BE6-II Hi-Lo alarm

[JTM]

My very stable and long running BE6-2 (~3 years) based system sounded the Hi-Lo warble which I take to mean that the system has detected an over temp condition. I shut down (power supply switch off) the system and let it cool overnight. This morning it doesn't even get to display the POST before the alaram sounds.

The CPU (PII 500Mhz) fan is working as well as the PS and Case Fans.

Any suggestions as to the culprit and possible points to trouble shoot would be appreciated.

Regards,

John

you might need to switch it on and off about 3/4 times in a row then it should pop back to life.

Many BE6-II boards have bad capacitors, that will fail sooner or later. Look for bulging and/or leaking caps.

I tried ten PORs in a row. The alarm sounds within ~10 seconds of power on. I doubt if it is a real thermal issue since it probably doesn't have time to heat up. I don't know what the alarm is (if any) for bad CPU power, but I'm guessing that it may be a MB voltage issue. I can't find any reference in the user's manual spelling out what if any alarms sound for bad voltages at the CPU.

Yup, I see three with bulged tops near the CPU, two show signs of leakage. The last time a changed a blown MB cap it was nearly all I could do to desolder it with the largest tip I have (1/8" screwdriver blade) for my 60watt soldering station. These multi layered ground plane MBs are giant heat sinks.

Any suggestions?

Yep! Look for 'Homie's posts--better yet look for him in Google. Maybe find him under "Capman". He replaces all 1000-mfarad and up for like $50 on that part. mobo--got a great reputation on these ng's for nice work. sdlomi

Try here--one in US, other in Europe?

I can repair it if you're in the UK....Homie does great work in the USA

 

[TomG]

most likely failed capacitors as the hi-lo alarm can also sound for a voltage problem. Homie or BigBadger both fix mobos:

Tom...Please note my new email address (same as the old one but 'big_badger' instead of 'bigbadger')...I got sick of the 150 spams a day the old one collected.

cheers

 

[TomG]

I'll update... thanks!

I know you've sorted the problem but you mention that "The alarm sounds within ~10 seconds of power on. I doubt if it is a real thermal issue since it probably doesn't have time to heat up."

Well it does.

Take the heatsink off you CPU and turn the PC on. 10 seconds ? 3 and it's shot !
