Is the air temperature high or is the laptop in direct sunlight? All laptops will overheat if you use them in a cruel enough environment. Obvious examples are stifling hot attics, vehicles without air conditioning in the summer and placed on hot surfaces. Hot surfaces aren't limited to radiators or desks touching steam pipes, they also include dark surfaces the get a lot of direct sunlight, even if they are located indoors.

Is the battery too hot? Some people are more sensitive to temperature than others, so using "too hot to touch" isn't a great troubleshooting technique. Unfortunately, very few people have a thermometer around capable of measuring temperatures through the normal operation range of a battery, including most computer technicians,

Have you noted that the fan never runs? Most laptop users are accustomed to hearing the cooling fan(s) straining away during certain intensive computing operations, and even the quietest, best behaved notebooks normally run the fan at low RPMs during normal operation.

Did you recently upgrade the BIOS? Anecdotally speaking, it seems that "my fan never comes on anymore" problems often occur after a BIOS upgrade. Manufacturers generally encourage users to install the latest BIOS version available for the model on the manufacturer's website, and if you call tech support with an in-warranty fan or overheating problem, the first thing they are likely to do is tell you to upgrade to the latest BIOS. The problem is, the notebook really should operate normally with the BIOS version you purchased it with, or they shouldn't have sold it to you.

how to Laptop Troubleshooting and Repair - Lenovo

Power Failure

If your laptop doesn't turn on when you hit the power button, the power system is a logical place to begin the troubleshooting process. The laptop power system can be viewed as three separate parts: The A/C adapter that gets plugged into a power outlet on one end and into the laptop on the other end, the laptop motherboard or power regulation daughter card that monitors and distributes power to the laptop components, and the battery. The vast majority of laptops manufactured these days can operate without the battery installed. In some cases, the manufacturers will suggest that you remove the battery and store it somewhere cool if using the laptop in one location for extended periods of time, as in weeks or months.

One of the oddities about troubleshooting laptop power failure as opposed to PC power failure is that the battery gives the laptop an independent power system for as long as the charge lasts. If the PC in your home is plugged into a bad power outlet or its power strip is accidentally switched off you'll quickly figure out why. But if the power strip gets turned off while you are operating your laptop, or a breaker trips, or the local power grid suffers a brown out, you might not even notice until the battery runs down. That's why it's important to not jump to conclusions about laptop battery failures, and to try charging the battery under different conditions before giving up and buying a new one. Just because the battery didn't charge while the laptop was plugged in doesn't mean the battery is bad.

Video Failure

Assuming that the video processor on the motherboard is working properly and sending the LCD instructions as to which colors to allow through in which screen points (pixels), the most common failure for laptop displays is a dead or intermittent inverter. When you can only see a very, very faint image of your operating system desktop on the screen, it means that the video system is working, but the LCD isn't getting any backlighting. The usual culprit if you don't have an LED backlight is the inverter, especially if you didn't note any strange tinting to the laptop display in recent operation, but it's not easy for the do-it-yourselfer to determine with 100% accuracy whether the failure is the CCFL lamp or the inverter.

Some display problems aren't difficult to troubleshoot at all. If you notice an inky stain slowly spreading across your LCD over days or weeks that you can't wipe off, the LCD itself is failing. Dead and stuck pixels often appear on LCDs over time causing point failures in the display. There's nothing you can do to fix them, so just tolerate them if possible. If the laptop is fairly new, the LCD may be under warranty and the manufacturer normally has a specification for how many dead pixels a LCD can accumulate before they have to repair it. Other physical problems that may require LCD replacement are cracks and chips on the surface. Horizontal or vertical lines or swathes of either a single color or dead pixels usually mean the LCD will have to be replaced.

Lenovo Laptop Won't turn On

So let me begin with the beginning of my computer troubles. I'm sure if this is the reason of my recent computer troubles, but you might know better than me. In May I split quite a bit of diet Sprite on the keyboard of my 2 1/2 year old lenovo Satelite Pro M15 laptop it immediatelyturn off, but I dried as much of it up as I could and left it sit out open all night it started up but the fan sounded kinda fun. It was still under extended warranty, so with the hope that they somehow wouldn't notice that I split soda I sent it in, but since my screen had broken spots they wouldn't look at it. When I got it back, the fan no longer sounded so back, and it worked ok.

They brings us up to recent times, about a month ago, my computer went static and my sound died. From that time on I've had nothing but problems. The sound has been static, or a high pitch beep. It had been freezing up all the time. And it often went to blue screen with the error stop 0x0000007F. Finally, last night I was working on it and it was actually working pretty good. I left for awhile, came back and it was off. I tried turning it back on, nothing. The LED light for the AC adapter ison, and the light for the battery is blinking. When I press power both go off then come back on. I tried taking the battery out and starting it, still nothing. I was wondering if anyone had any ideas what was wrong with it, if it was worth it to take it to get it fix or if I should try to get a new one. And if the new problems are connected to the spillage. Any response would be greatly appreciated, thank you.
