Most likely it's just a power regulating diode on motherboard right next to DC connector, that burned out. Minor repair, but expansive.

I just replaced the mobo in a Toshiba l555d s7910 laptop. It worked fine for about 2 months and now it wont power on. NO lights no anything. I have used 2 different power supplies one of which I know...


you should test or replace all leads make sure they are securely seated and are not bad/faulty that are attached to your (((motherboard to your hard drive))

one bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test the leads that attach to your ((hard drive from the motherboard)) or replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your ((motherboard to hard drive))

hope this helps

Laptop powers on fine , I can go into and change BIOS settings and everything is fine.. After the COMPAQ post screen the laptop wont boot from any media what so ever. It just displays a blank black...

or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

Motherboards power light is on, but computer is not booting


You need to tell us a lot more.
Like did it ever boot? Did you just assemble it? Are you getting any video signal at all? It is going through POST and cmos pre-boot?

If this is a first time installation, then I would suggest removing most of the wiring, like the reset switch, extra USB cables, or anything that could have remotely have gone wrong.
And don't do anything to it while plugged in. Motherboards are always powered these days, so turning off the power switch is not enough. Unplug it and wait for the light to go out.

Had a Bio Tech Motherboard installed with 2 G DDR2 Memory used Intel Celleron Chip (2.4 Gig HZ) . Problem-on Board Video goes blurry. USB ports after a few seconds hold no power. Tried memory, all cords...


The only common denominator is the computer power supply.
It is also possible that a power regulator on the motherboard is bad. I suspect its is the 5 volt power rail. The two common supplies on your motherboard are 12 volts and 5 volts. USB uses the 5v supply.
The simplest solution is to borrow another similar power rated computer power supply and put it in yours to see if the problem is fixed. If your power supply is rated at (for example) 250 watts or even as large as 400w, make sure the replacement is the same rating or even larger ie replace 250 w with a 250 w or a 400 w, but do not use a lower rated power supply. ie dont try a 250w to replace a 400w supply.
If the problem is still there another motherboard is the likely next step.
Before spending bucks, you could try disconnecting anything not really required to see if the power supply is indeed failing (often a burning smell from the rear fan is a good indicator). Disconnect things like dvd drive, cd burner, anything on the USB ports eg printer, external hard drives, modem, extra cards inserted into the motherboard on PCI slots etc etc, but leave the mouse and keyboard if they are USB devices. This will ease the load on the power supply and/or the motherboard power regulators. Basically you want a motherboard with only RAM memory, a processor and a video card with only a keyboard, mouse and monitor and the main bootable hard drive connected, and nothing else. See if you can get it working without the extra bits attached. you could then try shutting down and re-attaching devices one by one until the problem occurs. This could either prove the last connected device is drawing too much current, or more likely the power supply is failing as the load increases.
My bet is the power supply and they are cheap to buy. Make sure you buy the right supply. It might be an ATX supply with a 20 pin main connector which attaches to the motherboard (big chunky white connector). There are 24 pin models which don't generally work on the older motherboards that use the Celeron chips.
Good luck,
Steve

Laptop just stopped working.


There are various utilities which could help you recover data from your hard drive. If you are not comfortable using these utilities, please contact a professional data recovery technician.

There are multiple things that could be wrong with your machine, not just hard drive. Your power supply could have gone bad (Usually the cause of such problems). It could also be the motherboard.

Are you getting some beeps when you try to start the computer? If yes, the count of beeps can help you identify the exact cause of the issue.

WD Notebook Hard disk power problem


The power cord connects to a little circuit board inside the case, and the hard drive itself connects to the board. I would think that if you damaged anything it would be the board but not the drive. You could try taking the drive out of the case and connecting it directly to your computer (or you could get a computer shop or computer geek friend to do it if you don't feel up to it). If the drive itself isn't damaged you will be able to read your data.
