Some Things Cannot Be Fixed

There are some critical laptop parts that are very difficult and expensive to fix. They include the motherboard and everything that is molded on top of it, including the CPU (central processing unit) and the GPU (graphics processing unit). When you are sure that one of these are broken, proceed to the end of this article. For your next laptop, however, note that you can prevent damage of the CPU and GPU, by making sure they don’t overheat How To Fix An Overheating Laptop How To Fix An Overheating Laptop Read More .

Operating System

Symptoms: If your laptop sounds perfectly normal, if the disk drive seems to be working, and if the display turns on, but the system just won’t boot all the way through, the problem may lie with the operating system.

Hard Disk Drive / Solid State Drive

Your hard or solid state drive is the home of your operating system and stores all of your data on the computer.

Symptoms: Hard drives don’t always fail out of the blue. Sometimes there are warning signs, including:

  • slow / poor performance;
  • frequent freezes;
  • BSODs;
  • corrupted data;
  • accumulation of bad sectors;
  • strange sounds.

I have summarized all of these signs in an article on signs your hard drive lifetime is ending 5 Signs Your Hard Drive Lifetime Is Ending (And What to Do) 5 Signs Your Hard Drive Lifetime Is Ending (And What to Do) Since a majority of people today own laptops and external hard drives, which get dragged around quite a bit, a realistic hard drive lifetime is probably around 3 - 5 years.

A sure sign that your HDD or SSD has died is if the display turns on, the laptop’s indicator lights are blinking, but nothing else happens. You might see an error message that says something along the lines of a primary boot device missing. If the laptop is completely dead, however — no sounds, no lights, nothing — and if you have checked the charger, it’s very likely that the motherboard or one of its components has failed. In that case, proceed to the end of this article.

Fix: If your HDD or SSD has died, you can fix your laptop by replacing it. That is usually very easy. Remove the old drive, get a new one with an identical connector (IDE or SATA What Are The Different Computer Cable Types You Should Know As A User?

CMOS Battery

The CMOS battery provides power for storing BIOS settings when the computer is turned off.

Symptoms of a bad CMOS: The laptop mostly boots up fine and everything appears to be normal, except for some petty issues:

Any one of these issues can be caused by a number of things. But if a few of them coincide, then it’s a sure sign that your CMOS battery is failing.

Even on a laptop, the procedure is not so hard. The battery is usually accessible via the laptop’s underside. On some models, like my old HP Compaq nw8440, it might sit under the keyboard. In any case, it’s not as easy to access as the RAM or HDD / SDD, as it doesn’t come with its own door or panel. If you can manage to expose the motherboard as shown below, replacing the CMOS battery is just a matter of popping it out and replacing it with a new one.

RAM

The RAM is your computer’s short-term memory. It temporarily stores any information the system needs to run as it is running.

Symptoms of bad RAM:

Fix: Should your computer still boot, run a memory test Test Your Computer's Memory For Errors with Memtest Test Your Computer's Memory For Errors with Memtest Read More to check for errors, for example using MemTest86.

If that doesn’t solve your issues and if you only have one RAM stick, try moving it to a different slot. If you have two sticks, try booting the computer with one stick removed and try both sticks in different slots.

Should none of that work, try to get a working RAM module for a final test, but make sure you can return it in case it turns out that something else is broken.

Display

Until recently, I thought a display was almost impossible to fix. And then I dropped my laptop and my display was toast.

Symptoms: Other than obvious damage to the display, your display might not turn on at all. In this case, try to connect an external monitor, to exclude motherboard damage.

Fix: If everything works fine with an external monitor, chances are you can repair your laptop by replacing the broken display. I have previously described the process of dealing with a broken screen on your laptop Busted - How To Deal With a Broken Screen On Your Laptop Busted - How To Deal With a Broken Screen On Your Laptop Over the past couple of years I have traveled a lot and took my work with me wherever I went.

What If Your Laptop Is Broken Beyond Repair?

      If the A/C charger is working, this is most likely an issue with the motherboard. Unless you can repair it yourself (might require soldering), this is not worth replacing.

      I'd recommend salvaging parts: drives (SSD / HDD and media drives), RAM, and screen. Either use these yourself or sell them on eBay (especially the screen), then recycle the rest.

    Hi there! ive recently dropped my laptop and mostly everything is working perfectly, except for one small thing; it randomly freezes for a short period of time. It always freezes while im in programs such as Microsoft Office. I dont know if this is a software or hardware problem but Im hoping this isnt something to bad as I unfortunately do not have the time or money to get it repaired due to being a student, so if you have any suggestions please share! I'm a bit pushed for time as it is the end of the term!

    Thankyou so much in advance!

      Shannon, I would recommend you to take your question to a Q&A forum, where you will get quicker and more than just one response.

      Office can have a habit of freezing and it might not have to do anything with your computer. But if it affects a range of other programs, it could be that some piece of hardware either was loosened when you dropped the device or got damaged. This could be easy to fix (plugging RAM sticks or a cable back in tightly) or only a matter of time until it breaks for good (damaged hard drive).

      I urge you to make backups of your data to an external drive (or free cloud storage if you must), especially if you have school work that you cannot afford to lose.

      Best of luck!

    I'm a professional warranty repairman for a large OEM, and let me tell you, it is possible to replace a motherboard in a laptop, but it's rather difficult, and near impossible for the layman. But at the same time, if you can find out the part number of the motherboard for your model, they can be had, usually for a few hundred dollars, usually through eBay, and then pay somebody 1 to 2 hours to install it. Depending on the laptop, it's probably not worth it though. Take out the hard disk, copy off the contents, move them to your new box.

    The article is just great and i learnt a lot. However, Tina, I have a Gateway notebook. The 'B' key on the keyboard has a mind of its own. As a result i am not able to use the notebook for any application which involves keying in words, as the 'b' comes in bbbbbbbbbbbbb thus and refuses to exit till its made me mad. Initially i thought it was a virus and subjected it to all 'cleaners' and found that the machine was squeaky clean. Now am at my wits end. I know there is something at the B key base which is 'floating' because sometimes for short periods it works fine, and just when i begin to do serious work, it goes berserk, driving me nuts. Would appreciate any advice you may have on this. Thanks.

      November 11, 2013 at 8:57 am

      Only just saw your comment, Prem. Did you try to take off the B key? Keys can usually be popped off and back on. If in any way possible, you could also take out the keyboard and get the dirt out. A quick search on YouTube reveals several video tutorials about replacing a Gateway laptop / notebook keyboard; maybe your model is among them. Good luck!

    Laptop durability and parts replacement vary by brand and laptop line within a brand. For example, for more than a decade, I've bought corporate-retired Dell Latitudes. (This post is composed on an E4300 Latitude). These business machines are more durable than consumer laptops. In addition, these Latitudes tend to be modular, in terms of parts replacement. In the past, I've replaced LCD screens, keyboards, hard drives, memory and PCI Wireless cards with little-or-no-fuss, because these business machines seem designed for such replacements. Parts have been cheap, via Ebay. And, of course, their productive lives have been extended (reducing e-waste) by installing Linux.

    Many people would say that if the laptop cannot be turned on even though it's plugged toward an outlet, it's officially dead. But that's not the case, since technically there's something wrong with the supply switch inside the machine which enables it to draw power and if you can see lights, then you know it has power.

    I've fixed several laptops thanks to ifixit dot com. I was also able to buy a used laptop from eBay and fix it up nice as a gift for my sister. Best of all, I replaced the optical drive with a 1TB hard drive in my own laptop, so now I have 1.5TB.

    If a laptop screen is almost impossible to read except in a completely dark room, the thing that needs to be replaced is the Inverter board, not the screen itself.

    Display damage is probably the second most common issue I see with notebooks.

    The bar-none most common issue I run in to with laptops is damage to the internal AC connector. This may or may not be worth repairing. On most cheap consumer notebooks (many HP and Acer/Gateway/Emachines units), the connector is soldered to the mainboard. Even somebody with serious electronics skills will find that, once that connector has come loose, it's just going to happen again and again. Other laptops (Thinkpads) have a modular internal AC plug that can be popped out and replaced in as little time as it takes to get under the keyboard.

    Keyboard replacements are cheap and generally TRIVIAL. There's no reason to limp along with a half-working keyboard because of a liquid spill or suchlike. Some laptop keyboards (Toshiba) are also notorious for easily removed keycaps, so if you've lost a couple and it bugs you, feel free to pay the $15 - $25 for a replacement keyboard. Most keyboards come off after removing a few screws from the bottom of the laptop and perhaps one plastic bezel.

    Touchpads may or may not make sense to replace. On some laptops they're a modular component, but on many replacing the touchpad means replacing the whole wrist rest and top assembly of the laptop. That can mean a crap-ton of laptop surgery.

    If your 802.11 hardware stops working, buy a new internal WLAN card. Don't suffer having to dedicate a USB port to an external WLAN adapter. The cards come in two formats (Mini-PCI and Mini-PCI express, which Mini-PCIe having a couple different sizes as well). The slot where the card is installed is often under the same cover as a laptop's RAM, so it's literally a 90 second job to pull out an old one and stick in a new one. The internal cards often sell for $10 - $20 on Ebay and Amazon and unless you have some exotic need for a 3x3 802.11ac card, you'll be good to go.

    Anyone working on a laptop would do well to have a 2.5" SATA to USB enclosure on hand. They're $5 on Amazon and people will think you're a rock star the day you pull all their photos off their "dead" notebook.

    Some laptops are definitely better made than others. Some laptops are meant to be serviced and some are not. A laptop's price is not necessarily indicative of the level of quality - I'd rather have a three year old Thinkpad or Elitebook than a $2000 Vaio or Macbook. The one all-around suggestion that I make for people looking to buy notebook computers is to look at business products rather than consumer models. Dell sells Latitude. Lenovo sells Thinkpad. HP has Pro- and Elitebook. Toshiba has Tecra. I'll even grudgingly give Apple props for its notebooks. Those machines are generally a better overall investment than the sorts of computers one would most often find at a Best Buy or Walmart.
