    Hi guys so i have a laptop with a broken screen i use it via hdmi.. so I tried booting it up today but no success, ive already had problems with it not booting before, simply was resolved by keeping it covered in a towel till it overheated and automaticaly turned off after that it worked like a charm! But i tried the same method today and the laptop just wont boot at all....

    So when i power it on the led lights appear, the fan STARTS then STOPS 2 seconds later, to actually get the fan running I need to connect it to its ac adapter dont know why.

    Ive opened it up and i saw that the hard drive WASNT spinning, but it was receiving power when the ac adapter was plugged in, when i remove the ac adapter i cant feel any electrical current anymore.

    I can confirm the hard drive is working since ive plugged it in to a pc and its spinning

    Please help!!!!

    TY

    You bumped your post 4 times in under an hour with quadruple posting? Good luck getting help.

    Edited my post while you were responding. Not only did you bump it 4 times in under an hour, you also quadruple posted even with the alerts telling you not to double post. That's probably the reason you aren't getting helped is what I'm saying.

    Sounds to me like a chip has become lifted from the laptop's motherboard posibly one with BGA soldering. The old towel trick used to work on the old xbox 360s (xeno's) when there CPU or GFX chip would lift away from the board, your problem sounds very similar. as for fixing (if it is a BGA chip) is to have it professionally reballed and to be honest it's probably NOT cost affective and if you have it repaired it WILL go bad again some time in the future.

    My advice, the laptop has bite the bullet / gone to silicon heaven, see if you can backup the data from the hard drive and buy a new laptop.

    I can't believe that didn't solve all your problems.

    Why don't you start by telling us what model of laptop you have, and what behavior is specifically noticed when you try to boot your laptop with the AC adapter plugged in.

    Ok so my laptop is a samsung np305v5a, well when i boot my laptop the fan sometimes starts then stops afterwords, or it will start and stop and only gos on while connected to an ac, so I boot my laptop with a ac adapter no battery and the fan works fine but the hdd wont spin, which gets me thinking its the actual hdd thats not getting enough power, when its connected to an ac i use my screw driver that detects electricity and touch it on the hdd and it blinks meaning theres power there, so i guess its not receiving enough power to actually spin it.

    Does anything come up on the HDMI connected screen? If your hard drive isn't working, can you boot from a live CD or USB?

    If it only works with AC and not battery, it sounds like the battery is faulty and might have a short.

    If the fans spin when connected to AC but the HDD doesn't spin up, either there is a fault with the PSU on the 5V rail or with the motherboard during POST. At least you've ruled out HDD failure.

    Since you've cooked your laptop with the towel trick, there are any number of things that could be wrong with it (cold solder on BGA chips, leaking or popped capacitors, possible short circuits, etc). I personally think you've pushed it as far as it can go and now it's time to put it to rest. Statistically, 30% of all laptops will have a critical failure within 3 years of purchase (regardless of the brand that assembled it).

    Also, for future reference, there's no need to bump posts in the PC section of the forums for at least a week of posting. Most people here with technical knowledge will check and post 1-2 times a day, so bumping four times an hour is more likely to get you banned (rules against double posting) than get you help sooner. If you want a forum with so many techs posting that you have to bump every couple hours, try tomshardware.

    Hm... so is there anything I could do to actually get it working or no? Thx for the reply

    Cooked my laptop? Does that trick do damage to it?

    Does forcing a laptop to shut itself down due to overheating do damage? Yes, yes it does. It may work sometimes but every time you do it, it will create much more wear on all of the components until one part fails and needs replacing. The tricky part is finding out exactly which part has failed and if it's possible to replace.

    A repair shop could use a variety of tools to diagnose each part, starting with a visual inspection for any leaking or popped capacitors on the motherboard. If it were a desktop, a PSU tester could be obtained cheaply to check the voltages. For laptops however, it's a little more complicated and I don't have enough knowledge on the more specialised diagnostic tools that exist on the market. Generally, you could take the laptop to a repair shop and hope they won't charge too much to take a look at it.

    Otherwise, all you can do is try and find out exactly what part is working and what part is not. There's no set way to this other than experimenting with different things and seeing if anything changes your situation. You can try taking the HDD out and seeing if that lets you get to BIOS. You could try taking out a stick of RAM, then swapping it with the other RAM to see if one of them is faulty. You could try leaving no RAM inside and seeing if it beeps at you (many BIOSs have beep codes for CPU, RAM and GPU faults). You could open it up completely and look all over the motherboard to see if there are any leaking or popped capacitors. It may sound like I'm pulling at straws here, but experience has shown that stripping a computer down to its minimum parts has fixed non-booting issues in the past. But I still am of the opinion that, based on the information provided, it sounds like the laptop is just dead (at least you can always copy the data off the HDD into another computer/laptop).

    What made you towel it? You may have done more harm than good there.
