dell inspiron laptop repair

While learning how to use my new AmScope microscope, its camera and related software, I noticed that the fan in my Dell 17R Inspiron laptop was running too much.




It is 4 years old and time for some (PM) preventive maintenance. It also needs a new headphone jack. I bought a new jack several months ago for it. It’s been a good laptop so far.

Here are a few photos of the laptop and the 1TB hard drive. You can see my Staedtler eraser pen that I use to clean the ribbon cables with in the above photo. After I clean them with the eraser, I clean them with alcohol.

The laptop wasn’t very dirty. I try to keep the environment as clean as I can. I also use a lap base under the laptop that has 2 fans blowing onto the bottom of the laptop to help keep it cool.

The thermal grease wasn’t too hard but it was definitely in need of removal and replaced with some fresh grease. I used my Arctic Silver 5 thermal grease.

Now my new thermal grease is on and the heatsink ready to be remounted.

You can see in the photo above that I was sold the wrong headphone jack port. At least now I have had a good look at it and can try to find the correct one. The coin cell battery still had 3.267V, so I left it in. I may replace it with a new battery after I find the correct headphone jack, and replace it.

Putting the new thermal grease on the processor and heatsink was the most important thing. I’ll get back to learning how to use my new microscope camera/software and get going on the first Accutron article. It will be a busy week since my granddaughter will be born any day now. I can’t wait to see her beautiful face! I was hoping to include the headphone jack repair in this article. But that’s the way things work out sometimes. At least I hope the article inspires people to take preventive maintenance seriously. A little preventive maintenance now can save us a lot of money later!

Most people seem to think that PM only applies to our cars. Hopefully taking good care of my laptop will help it work great for many more years.

Above is a photo of my new microscope. It isn’t the best microscope available, but is all I can afford right now. It is an AmScope SM-4TZZ-144S-3M. It has a 3MP camera and a 144 LED ring light. Right now I have it setup with the 2X Barlow lens so I can get the closest photo I can get of the Accutron 214 index wheel and tiny jewels. With the 0.5X Barlow lens I can get a pretty close look and still have about 6.5 inches of working distance. It seems to be adequate for my needs. I had to move my oscilloscope up a level to make room for it.

Here is a close-up photo of the index wheel and jewels. You can see how dirty they are. This is the closest my microscope can get. I’ll get some better photos of them after I take the movement apart. It has a lot of glare from the light shining on the metal movement.

I hope you guys enjoyed the article and the sneak peek into the next one. Thanks and Happy New Year!

    I noticed that you have stuck a dollar bill on the laptop screen. Any particular reason for this? And congratulations on being a grandfather, sending you my best wishes.

      Thanks Roshan. I have a grandson, and now I will have a granddaughter! I have the dollar bill covering the camera so my government can't look at me whenever they want.

    Great! You are right; we need to do PM. But like a washerman, we do not get time to attend our own home appliances and devices!

    Hi Robert

    I agree that most of the people believe that preventive maintenance refers more or less to cars, the electronic equipment being excluded. And of course this is a wrong notion. In contrast to it, I would add to the preventive maintenance work the evaluation and/or recaping of all either degraded or cheap quality electrolytics of the equipment we intend to keep in top working condition and as long as it gets.
    Happy new year Robert. And (according to what I read) be a happy grandfather as well!

      Thanks Andre. I wish I would have been able to get a better one but couldn't afford to right now. The more I play with the camera and learn how to use it, the better it seems to work. I don't know much about photography anyway, but I'm learning. But the microscope is much better than the camera shows. The view through the microscope itself is amazing.

    A happy new year to you too Robert and congratulations!
    About your Watch: If I'm not mistaken my friend the Watchmaker cleans old mechanical Watches from build-up grease and dirt with his Ultrasonic Cleaner. And afterwards he gives new special oil to the wheels and the diamond jewels in the Watch. And bad jewels and axes get replacements. But that is probably all I know about Watches.

      Thanks Albert. Yes, and watchmakers can make parts themselves when unable to find replacements. I only consider myself a student.

      Thanks Yogesh. I wanted a microscope with ordinary optics and a large working distance. I may get a USB portable microscope next. The Arctic Silver 5 seems to be pretty good. I haven't tried Noctua.

    Hey, good on ya Robert for doing PM work....I admit that I only
    perform reactive maintenance as I abide by the ol saying...." If it
    ain't broke, don't fix it" though your reasoning may change my
    attitude on this subject. Looking forward to the next chapter of
    your repair on this equipment mate.
    Cheers

      Thanks Anthony. I agree with you, but PM is not fixing it, it's helps to keep the device from breaking prematurely. Heat is an enemy of processors, and fresh thermal grease helps keep it cool.

    Hi Robert, you are correct, PM is essential for everything. Regarding my laptop I tend to be a bit lazy. After watching a 35 min video on how to pull a Sony Vaio apart I postponed the operation but one day I will have to do it! One of the viewers wrote that we also need another video on how to put it back together 🙂 I tend to agree...
    Thanks for sharing. Cheers, GM

      Thanks Gerald. Lol! I have heard about the Sony Vaio. Just be careful and take plenty of photos. My Dell Inspiron was a piece of cake. It almost puts itself back together. My friend Michelle's HP Pavilion was much more difficult than my Dell. But delaying the PM will shorten the life of the processor IMHO. I hope you send in an article on the PM when you do it.
