Computer may have failed permanently

[CoolMe]

Probably a power supply or corrupt CMOS/BIOS.

With a corrupt bios, the laptop won't boot Windows at all (or any OS), it can't even access the bios menu..
It could be a psu issue, can't say what to check or fix since it's a laptop, unlike with a desktop pc, you just change the psu..
Or it's the mobo for some reason, though doesn't explain how other components work fine (CPU etc.), but not the fan pin connectors..

Sorry to hear that. I know it sounds silly, but if you find out it is bad mobo, you can always open it up and with volt meter find a 12 volt rail on mobo, or going to DVD drive, then run it directly to that fan. Will run all the time and be noisy, but better than nothing, or pitching it. Good luck!

Quick solution i can give:
Buy a CPU Cooler that uses external fans, and use a regular fan powered by 12V from power supply unit < it will be on max speed always, and wont be able to monitor/control speed, but it will do the job >

Or you can adapt a smaller fan that fits over the original heatsink < removing the built-in fan > and power it with 12v (pushing air downwards)
********
fact: i did this last suggestion on an old AMD Athlon long time ago, where cpu_fan connector was broken and had to improvise. i used a small fan that i found on scraps from other electronics and only had to screw the new fan on the original heatsink, powered it from psu and it worked pretty well for home/office use. I didn't do any compiling or any other high demands procedures
<<< Just make sure the new fan supports 12v >>>

Alright, it appears to be a power issue. It should be fine on the cooler, but I don't know about compiling something too intensive. I'll check out computers on Newegg this weekend.

this model uses 5 volt fan

It's bad that in this model CPU (and video) are soldered into the motherboard, motherboard comes out expensive.
For example, variant with i7 2.8GHz & Nvidia (P47D9), refurb. is ~300$.
(the exact model of the motherboard will still have to be found out)

btw, as I remember Dells have Diagnostic menu with logs somewhere in "BIOS". Does he write something interesting there (or earlier, before changing the fan)?

I personally like Micro-Center also, if you have one near you. They are really good about taking back items, or repairing them.

 

[ArgoRV]

Oh i just read. It is a laptop.

have you tried to connect GND and 5V to a battery to see if it spin?
if it does you can wire power from the usb connectors, any technician with good soldering skills can help you do that

 

[r1vver]

This will result in loss of control over the fan speed. It will be need to constantly keep it (fan) at maximum speed to avoid overheating of the processor.
And "BIOS"'s diagnostic logs will be filled with "processor fan failed to respond correctly", these laptops are too smart now.
Tho the idea is good. And definitely cheaper than motherboard repair.

I turned on the computer with the bottom open, while it was in my hands. The fan failed to spin.

The bearings in the fan could just be shot or the fan motor, it's not uncommon for these to crap out. I wouldn't go replacing a motherboard or the entire laptop without first trying a replacement fan.

Except he already did..

He already tried actually, think he bought 2-3 fans to try already, seem to be issue with his motherboard.

yeah, I already did, and I took it to a professional that has 5 out of 5 rating. he says it's the mobo or more specifically a power issue with the motherboard.

Damn, must have miss that part. Been awake for too long. You might be able to splice into another 5 or 3 volt source on the mobo though and at least get the fan running until you get get a replacement. Possibly from a usb port.

Watcha talkin' bout, boi? you forgot to take your dementia medicine (again)?

 

[AncientBoi]

Reading all the replies, sounds to me it's Just gone. duh

Yea, something's gone alright..
