I had an excellent experience with JL computer service. The customer service was truly high quality--friendly, professional, and patient in explaining everything clearly. I really appreciated how responsive and honest they were throughout the process. Jack (the owner) went ABOVE and BEYOND. He came in when the office was CLOSED to work on my laptop in order to meet my timetable. I wouldn't hesitate to recommend them to anyone looking for reliable, top-notch computer repair. read more

A great computer repair place. The service is excellent and the pricing is incredibly reasonable. JL Computer Services is a great place for computer novices and experts alike to receive high quality and prompt help. read more

Second time I've come here and I've always had a pleasant experience. My Mac laptop battery went kaput and Alan was able to fix it and replace it within a day. I dropped it off and he kept me updated on the status, which was amazing. They do both Apple and Windows products. Def recommend a stop here! read more

Great experience. Jack was helpful and friendly and had the parts and expertise to fix my computer quickly. I would recommend!

great service! honest! friendly! highly recommend! Was able to squeeze me in last minute. Definitely getting all my PC work done here in the future. read more

When our old HP ProDesk desktop refused to start one morning, we took it to Jack on the strength of his previous Yelp reviews. Everyone was right! He was incredibly fast and professional. and solved our problem overnight. He also ported everything over to a newer machine that we had purchased online from a refurbisher, and his overall bill was very reasonable. Super nice and knowledgeable. Highly recommended. read more

My Samsung phone got tossed around in the washing machine for 20min til i realized where it was. Tried all youtube suggestions, but It was a goner, with 2000 pictures/videos of trips, kids, etc. (Long story re: backup issues.) Opened the back along with one layer of the works, then stopped. On a friend's rec, took it to jL Computer and Alan Monticelli reviewed the damage with me. In about 6d, with some miracle cleaning work, re-testing various parts, and a new battery, I COULD ACCESS ALL MY PHOTOS/VIDEOS! I cannot tell you how grateful I am for their quick and knowledgeable work. I was warned it might not be possible, but they pulled it off. Thank you, thank you!!! read more

We thought we would need to replace our 4- and 8-year old HP Envy laptops this week. But we took them to Jack at jL Computer Services to see if he could help us. We knew the batteries were dead and had tried last year to replace them but they are no longer available from HP. Even plugged in, they were not running well. Jack thought they would need new batteries and maybe a new solid state hard drive to replace a mechanical one in the older laptop, for which the total cost estimate was $400. Two days later diagnosis and repair completed: Only needed the two (off-market) batteries and some OS software clean-up. Total cost was $300. The PCs are now working well and we are delighted! read more

After spending close to 7 hours with Microsoft W11 support working on fixing multiple Blue Screen of Death failures on my 2 year old Lenovo Flex5 14ALC05 (you do not want to own this model), I brought the machine to Jack to help me with a fresh install of W11. As always, Jack was very helpful and responsive. After multiple software fix attempts including setting up some BIOS options for "Secure Boot" and "TMP2.0", Jack diagnosed the problems with the laptop as multiple hardware failures including, but not limited to, the mother board due to excessive heat from its AMD processor which showed the machine running at 80 Centigrade on start-up idle. Jack's current diagnosis coupled with the fact that the machine had already had a mother board replacement from Lenovo in the first 3 months in service less than 2 years ago helped Jack write things up so that I was able to present them to Allstate/SquareTrade for a full refund for the price paid, albeit with some haggling with the processing agent. Thank you, Jack. Highly recommended. read more

We wanted to install bigger RAM for our son's laptop. It should be a simple task for us to do; however, we could not get one of the screws out because of the broken stand-off. We took the laptop to Jack. He is super friendly and quickly came to rescue. He took off back cover very quickly - so fast that I didn't get the chance to see how he handled the broken stand-off that gave us troubles. Within 10 minutes, our RAMs are upgraded and the charge is very reasonable. We are so happy. Jack and Allan are always our go to guys when we can't fix something by ourselves!! Highly recommend!! read more

They were responsive, knew what they were doing, and didn't overcharge. A solid business. I'll use them again.

Jack was very helpful and responsive. Although the laptop was determined not fixable due to hardware issues unfortunately but the he was able to provide me the details on what has been tried and then came up with recommendations that I could try after ruling out certain potential problems. Would recommend. read more

I tried to replace the battery on my laptop and ended up making problems worse. These laptops are much smaller and more fragile than they used to make them! I brought the laptop over to jack, and my shameful zip lock bag of broken plastic connectors expecting bad news. Jack got right to work disassembling the laptop (taking ALL the screws out and not breaking anything like I did), finding the three ribbons that got disconnected, and had me back up and running within 30 minutes of walking in the door. I'm hoping not to break anymore of my own stuff, but if I do, I know where to go. Thanks Jack! read more

I've stopped by jL a couple of times, once for my laptop with a busted hinge and once for a PC I built that was having issues. Each time, Jack was able to quickly diagnose and repair the issues and get it back to me within an hour or so. Very impressed with this shop and it'll definitely be my go-to for any future needs. read more

I gave an earlier good rating to these folks. But last week I went back because I had a defective external drive they installed a few months ago. They were very nasty. First, they lied and said they never carried that brand. But I persisted and they finally agreed that I had bought it from them and they had configured it. Besides being unhelpful they became personally rude. I do not recommend his folks who have no concept of customer service, or indeed, how to get along with their customers. read more

I've used this company three times now with good results. Very fair prices for service, and good work done in a timely manner.

If you need to build a custom PC or if you need to fix, clean, or simply upgrade your computer parts such as GPU, CPU, RAM, Hard Drive, Jack can do it. They can also remove malware and viruses from your computer. read more

jL Computer Services - EK water cool kit by Jack. - IT Services & Computer Repair Near Me - Gaithersburg, Maryland

Needed some basic service done. I shopped around, they had the lowest price. Their work and customer service was great. They are a local business that I am happy to support. read more

Great fast service and reasonably priced. Amazing job fixing my broken laptop. A+ experience.

Terrific. Helped save my Mac after I feared everything was lost. Quick service. Very reasonable. Highly recommended.

A friend referred me to jL Computer Services in February 2018 for issues I was having with my Dell Inspiron Windows 7 laptop. Jack was very helpful, very easy to talk to, and explained the problem without a lot of technical jargon. He was able to fix my PC on the spot and at a great price! I have worked with him several times since and he helped me troubleshoot problems easily. I can't say enough good things about his honesty, hardware and software expertise, and willingness to help. I highly recommend him. He is my Go To technical support. read more

if you're reading reviews and trying to decide where to take your laptop, don't waste any more time! I had a 9 yr old computer w many pics and files I wanted to keep, but the machine was beyond slow. A friend suggested I get a few new drives and he would help me, but his intentions were better than his guidance. Jack cleaned up the whole mess, went above and beyond what was expected in servicing the laptop (HP Envy). The was a slight miscommunication (99% most likely on my end), but he and Alan were extremely gracious, and Jack gave me a break on the correct component that I needed. I am amazed how fast it runs now, I didn't think that it was possible! I feel very fortunate that I took my computer here, and is nice to know I have a great shop just 15 min from me! Thank you so much Jack! read more

Jack of JL Computers has been my one and only go to guy for computer needs and repairs for over 10 years. The best for price, service, quality. Both Jack and his partner Alan for the Apple crowd are exceptionally knowledgeable and terrific people to work with. They almost always have done the repairs ahead of schedule, below what anyone was close to quoting and low and behold their repairs hold up. Never a question where I am taking my computers for repair....JL Computers!! read more

I take care of most computer issues on my own, but I ran into a problem where I needed some outside help. They took care of my issue pretty quickly & for a reasonable price. I will probably just use them in the future instead of struggling to figure things out on my own. I would definitely recommend JL Computer Services to others. The owner is very friendly and knowledgeable. read more

Very fast and very educational. Have recommended them to others already. Great work! 5 stars.

My laptop is now 7 years old. About 6 months ago Jack replaced my keyboard, it looked new! Last week my laptop went back to him for an SSD hard drive and a new fan (my fan got noisy). Once again the work was excellent, this old machine has a new lease on life (and considering the $2K initial price I want to get as many years as possible). I do miss the Computer Place, but keeping Jack has solved several problems last year, including a cell phone repair for my Granddaughter (Jack has a Cell Phone expert working in his shop also, and he does Android and Apple) read more

JL Computer Services is one of those little neighborhood gems that you wish you knew before going to Best Buy. Tucked in an office park in Gaithersburg, Maryland, it is a modest establishment without all the expensive trimmings that you pay extra for in larger fancier places. The owner Jack Liu is an IT professional specializing in repairs, however he will order or build new computers if that's what you need. We used to take our computers for years to Jack who worked at The Computer Place for repairs. When they closed down, Jack opened up his own shop. Jack is always honest with very fair prices, lower than any other. And what a fantastic job he does! He's always accessible by phone too, no playing phone tag. Today I brought my new computer and old computer in. The hard drive just needed to be switched from the old to new. I didn't know that! I mean I knew the hard drive had to be switched but in my ignorance I thought Office had to be reinstalled in the new one. I know, I know, stupid, right? Jack didn't charge me for the switchover and he was honest telling me that Office would automatically transfer to the new computer. I would have been easy prey for someone who was less honest. While I was there I overheard him patiently explaining and instructing a very senior lady how to perform an apparently simple task on her computer. He solved her problem and she left smiling. Great shop and most highly recommended! read more

Always the best service ! The only place I will take my computers to be taken care of !! Thanks Jack !!!

JL was recommended by an IT guy from work. I needed technical guidance and likely a new computer. Jack was open to any question and provided balanced, honest and frank feedback including how best to use some existing accessories vice replacing all. Needless to say I went with a custom build and can't be more pleased. Jack answered questions after normal hours, Definitely a better way to go than the big box and buying what they give vice what you really want and need. read more

After the owner of The Computer Place retired, closing the store, Jack, an excellent an honest IT professional opened his own business, and kept the same phone number. He is really, really knowledgeable and capable. His services are reasonable and honest. I will keep going back to Jack when I need help, and recommend him to others. read more

Jack Liu was great. I took my laptop to him in the morning. He called me in the afternoon to explain my problem (my hard drive failed). He was able to retrieve my data and replaced my hard drive. I picked up my laptop the next day. His price was very reasonable and service was fast. He even gave me a suggestion to replace a program I had been using. Knowledgeable, honest, friendly, and professional. If you need a computer repair, this guy really knows what he's doing. Highly recommended. read more
