If you have a voltmeter, it may be helpful to check the voltage across the fan when it is running fine (5v or 12v) and when it's making noise. If the voltage drop is significant, it could be the stator coils shorting, causing desync. This could eventually result in a dead-short failure, possibly damaging the motherboard, or depending on the power supply, ...

I'd suspect, that those drives haven't failed at all - they were just running out of their specs and should be fine when plugged into a different computer. Let me explain: You use the USB ports of your Yoga for two purpouses: As a data connection, all fine with that As a power source for the drives, and that might be the problem. Now the Yogas are ...

Sounds like ultimately you may need a new motherboard. As for how to diagnose it, a multimeter may help in determining if/how many USB ports simply don't work anymore. If they don't read 5v, they won't work. I suppose it's also possible they are delivering 5v but the data is down (governed by a chip on the motherboard). Your CPU should be fine but until you ...

I will try to answer these questions based on the fact that I buy most of my PC components online and I have built and shipped computers for remote clients in the past. Question 1: I have shipped fully-assembled PCs in the original case package before, because this is what it fit in. Whenever I did this, however, I was careful to insure the shipment for ...

Since you said that applying pressure by the Esc key, my guess would be that the flex cable that connects the display to the motherboard is damaged or loose. I recommend changing it. Sometimes, when such cable damages, certain issues can occur. For example, the screen splits in a strange way, black color appears washed out, some colors change for others (i....

Without actually seeing the state of the laptop's physical condition and running some diagnostic software on it, right now, a best guess is about as accurate as you are going to get. The laptop fell. This can cause all sorts of problems. You mentioned that the lid wasn't aligning properly any more so that means there is some breakage and/or twisting of ...

On the short term - it should be fine, unless there's obvious issues. Its a high end PSU with a ton of legs. You do want a more modern PSU eventually - there's no support for c6/c7 states in older PSUs, and that may cause issues, but the fix is trivial - turn off those states in bios if you have issues. Typically when a PSU does die, it rarely takes out ...

component shipping: anyone who knows what happens to a boxes in the mail (but only sometimes) would doubble box up things like motherboards, hard drives, gpu cards, fans and PSU. less nessisary is unattached heat sinks, power supplys, smaller cards like sound cards and usb plugs and other lightweight plug-in items that have already sufficient packaging ...

Does computer components' original packaging provide enough protection for safe shipment? Yes, if precautions on the packaging (e.g. fragile, temperature / humidity range) are followed. I see a lot of comments about motherboards failing within a few days/weeks. Is this related? Can be related to bad treat during shipment yes, but it's very ...

Other than it being extremely annoying, you won't damage anything in your computer. If the temp threshold is exceeded, your computer will slow the processor and eventually shut down the computer to avoid damage. If you put an small portable fan to blow air into your case, you should be fine. I have done this in emergency situations when a fan died on a ...

This is just a shot in the dark: I think you have some sort of issue with cables - perhaps even issue inside LCD panel itself. If your laptop is still in guarantee period, simply send it to service. If not and you are handy enough, try (with caution): disassembling the laptop unplugging LCD cable from motherboard and LCD panel itself and plugging it ...

It's likely CPU/GPU/NB chip dead. Requires repair by chip replacement via soldering. In this model integrated video is on-chip with north bridge and CPU. It can be a LCD matrix or a cable from the motherboard as well. This can be verified easily: connect external display - if the picture is fine on the external display then the issue is with the display.
