Comments on: What Happens When Your Laptop’s Motherboard Goes Bad? Geek Culture & Tech Expert: How Can I Help You Today?

Nowadays many many functions are integrated into one chip, the CPU. If you are trying to find a DC regulator on the motherboard, forget it. There is a big chance that It is in the CPU itself. So the motherboard could be still good and the CPU could be bad. Think twice before you try to replace the motherboard.

The heat difference is amazing, the laptop runs quiet, more enjoyable and comfortable to work on and less of a chance of dust built up or something going wrong due to internal overheating.

Much like what Vlad & Igor, The Dangerous Brothers do with the Firmware updates for DVDRW Drives,except this modded update would corrupt a particular video bios !
I mean it could be done!

Yes in My opinion a virus can fry your mobo cpu or any other part of your PC by working it to death & not allowing it adequate cooling & with the various tools & scripts in the wild it doesn’t take any imagination at all to see it.

It’s common knowledge that a hacker can work your PC both remotely or with various tools, just as if sitting at your desktop.
We also know there are tools that can both monitor & shut down the fan on your PC.

So say the hacker decides he wants to fry PC’s for some strange reason, so he puts a small file on your PC that loads before your OS or your AV(they are out there) & by doing so some how disables the thermal security monitoring program within your bios.

So now your laptops been told to ignore all temp warnings & to just keep rite on running(you’ve seen this setting)
Or better yet now days there are thermal diodes that respond to various programs allowing one to adjust the fan & ram settings from within thee OS upon reboot.

Say the hacker placed a small program on your PC(1 file in size) it tells your CPU Fan to shut down & stay shut down!
Then your laptop starts getting hot!
Way too hot like 82C or 180F !

Needless to say you wouldn’t get to boot into too many of these environments before you would jack the various diodes, capacitors & other components on your mobo, not to mention the cpu & ram (Heat the Great Destroyer).

I had a Vaio some years ago. The left mouse button broke. I asked a computer mechanic to fix it, and he told me that not only would Sony not sell the part, they insisted that I send the entire computer in so that they (Sony) could run a software diagnostic on it. Such proprietary attitudes make my blood boil and cause me to keep my wallet in my pocket. I advise all of you to do the same.

Cheers, Bruce

Those things can be a pain to disassemble, I had to replace the motherboard, because heat didn’t transfer as normal on the cpu. It had a wave on it. Why? Years of dust on the heat sink……. #1 on my priority list of maintenance of laptops. (and i’m just a regular guy, not certification or anything). Heat and dust, the laptop killers. Just give it a try, open your laptop, remove the heat sink and give it a good clean to it (not just blast air into it, you will compact it), and apply a good thermal paste to it. You will feel the difference on it.

I am unsure of what a “logic board” is, but the Motherboard is the main board in a computer on which the CPU (Intel, AMD, or whatever) is mounted and to which peripheral cards are mounted via connection slots (ISA, PCI, PCIe, RAM Sticks, etc.) and to which connectors are connected leading to various input ports (USB, Firewire, Parallel ports, Serial Ports, eSATA, etc.). It is generally the largest printed circuit board in the computer.

In a laptop, chipsets for the various peripherals, such as video, audio, Ethernet, etc., are generally installed directly on to the motherboard to save space. Some of the specialty functions might come on cards for insertion into external slots like PCMCIA or, more recently, eSATA.

Of course, anything that is “upgradable,” like RAM and hard drives, is kept separate and removable/replaceable. Unlike days gone by, it is virtually impossible to repair or upgrade a modern motherboard at the component level. They are manufactured in multiple layers, with solid state circuitry contained between the layers, just as in a semiconductor chip. The parts that ARE exposed are so tiny as to be impossible to desolder/solder/and otherwise manipulate, and usually so close to each other that such processes would be impossible without damage to neighboring components.

I have recently repaired a circuit board in a hard drive, and that was hard enough, but I got my information off of that hard drive and backed up elsewhere, and now I use that drive for experimentation, to the point that it fails.

You didn’t say how you determined that the graphics chip was bad. Like Chris said, I’d get a second opinion on it before I read the Laptop it’s last rights.

One more thing. If you have been using the laptop without good ventilation (on your lap on a down comforter, for example) and it’s been running hot for long periods, this can cause damage to your system as well.

I recall a rare case where a virus fried an EEPROM chip by sending the chip into a steady write cycle, possibly with overvoltage turned on. You don’t have this though – Virut, as mentioned above, carries no hardware damaging payload.

@Kitty: Blame the points system :p I hope I’m ‘other’ people!

She did – it was only a 1-GB stick of memory I had added and which had worked fine for about a year. When her friend removed that bad memory the laptop ran fine on the 512 of memory installed by HP in out-of-reach location. There’s a second slot which allowed for upgrade, which I had done with the Crucial.

We got a new 1 GB stick (different brand) from Newegg, she installed it and “her” laptop is still running since about a year ago. My loss, her gain. And just in time since her desktop had died just couple of months before and she couldn’t afford a new one. I’ve lived long but still learning.
