t5400 strange errors
so my t5400 crashed and wouldn't recover, bad memory controller. So i bought a replacement MB on eBay. installed it, machine powered up, and i tried to set the configuration. it restarted and wouldn't post. only 2 short beeps.
so i did everything shy of sacrificing the chicken under my desk, gave up and retried today. plugged it in, started up no worries, needed to set the bios for the SSD. rebooted. nothing. 2 short beeps.
Any ideas?
Thanks in advance

i know it's not a published error code, and it's 2 short beeps. just 2. and like i said, system powers on and posts 1 time, gets as far as it will get with a bios not being set, reboots & won't post. and it really is just 2 beeps. 1,2,3 are lit on the front. and how do i edit my previous post?

Check color of 4 diagnostic LEDs on front of case when it won't boot. Error codes here. <ADMIN NOTE: Broken link has been removed from this post by Dell>
Two beeps is not a published error code <ADMIN NOTE: Broken link has been removed from this post by Dell> for Precision T5400. Could it actually be 2-2-2, which would be a RAM error? Open case and reseat RAM modules in their slots. Make sure they're installed as matched pairs in the correct slots too.

Repeat the process but swap all RAM modules into slot 1, one at a time. If you identify a bad module (eg, PC doesn't boot), you will have to replace that module as a matched pair even if the other module in the pair is OK.
If all modules work in slot 1, add one to slot 2 and do the "battery thing". If that works, keep populating the RAM slots including the "battery thing" until you ID a bad slot or all modules are reinstalled.
If it fails no matter which RAM module is in slot 1, you may have a motherboard failure, CPU failure or video card failure. Since you've already replaced the motherboard without solving the problem, that might suggest a CPU or video card failure.
If you can reinstall all RAM modules and it boots OK, reinstall one PCI card at a time until all are reinstalled or you ID a bad PCI card. Do the "battery thing" each time you add new hardware. If you can successfully reinstall all PCI cards, then start reconnecting drives etc...
