Perhaps the title is a bit dated, as the last newish computer I took apart didn’t actually have a PC speaker, and this thing doesn’t actually make any obvious noises while it fails to start.
I have a notebook that died recently. CLEVO D900K.
When powered on, all the pretty LEDs come on normally, the clock is correct, the display changes from off-black to on-black, disks begin to spin up… LEDs blink… disks begin to spin up… LEDs blink… disks begin to spin up… etc. until it’s turned off.
Nothing I’d associate with POST is displayed (BIOS info, RAM tests, etc).
I’ve tried starting it with a LiveCD- no change from above sequence
I’ve checked the seating and connections of the easier-to-get-to internal components.
I came home from work one day and it wouldn’t start. Hellspawn the First helpfully informed me that my computer was broken before I even tried to turn it on, though ShadiRoxan denies any knowledge of traumatic damage.
Its native power supply is a surge suppressor and it’s plugged into a lower rated surge suppressing power strip.- neither indicated having tripped, no other devices on the strip are acting wonky. So I don’t think it was a power spike that cooked it.
Sooo… There any computer voodoo on par with the old POST beeping of which I’m unaware that might help isolate the problem?
As it’s a laptop you can plug it into an external monitor and see if you can see more; that will help if the screen is (part of) the problem. Aside from that, no, without knowing some detail about what was done to it to make it fail (and it really sounds like it; being dropped or whatever), I think it’s a repair shop job.
The screen appears to be functioning normally. It just doesn’t seem to be getting to a point in the S/U process to where there’s anything for it to display.
I’ve had computers die due to memory or disk failure before, but it doesn’t even seem to be getting to that point. Normally I’d expect so very low level hardware troubleshooting codes (thus the POST beep code question), but I haven’t built a computer in so long to know if desktop systems will still try to tell you if, e.g., there’s no CPU installed. I’ve never tried building a laptop from parts.
I can dig an old monitor out of a closet and see if it is a screen problem, but I have a feeling that’ll just stay blank, too.
