I didn’t want to disassemble the ancient Dell Latitude D620 laptop, but something forced me and for good reason

Hi all! I received an old laptop Dell Latitude D620, apparently “American”, it didn’t even have a Russian keyboard. It was necessary to prepare it for sale; it initially worked on Windows Vista. It was decided to add RAM, install Windows 7, and test performance.

The laptop had not been opened before, it worked quietly, the components were nothing special, even for its time: dual-core Intel Core 2 Duo T5600 1833MHz processor, DDR2 1 Gb., HDD 60 Gb, Mobile Intel 945 Express Chipset Family 256 mb graphics. There was nothing special to warm up to, I thought that I could get away with expanding the RAM and reinstalling the system, why bother with a stable working device.

Installing RAM was not particularly difficult; I threw out two 512 MB sticks and installed two others (2 GB and 1 GB). Although disassembling for replacement is not so simple, one slot is replaced through the tray, just unscrew two screws, but the second slot is under the keyboard. In general, it’s also not complicated, you just need to disconnect the bar with the button panel and remove the keyboard.

I replaced everything and installed the 32-bit version of Windows 7. I installed a basic set of software , which I already wrote about in another article. I tested the work in browsers, YouTube videos can only be watched in 480r quality, anything higher is slow. It turned out to be a normal office machine for working with text, surfing the Internet and some multimedia tasks. The toys are only very old. I did not notice any disconnections or defects. Turned off the laptop and put it aside.

The next day, I don’t know why, but I really wanted to see the operating temperatures. I launched AIDA64 and saw temperatures under 70 without load. A decision was made to disassemble it, but this is a tedious task for this model, even the matrix with the cover needs to be removed. Well, it’s necessary, I took everything apart and supposedly the cooling system was completely clogged with dust. At the same time, I updated the processor thermal paste and the chip thermal pad. Now the temperatures have leveled out and are 40-60 degrees, this is normal for such an old man.

It’s good that I disassembled it and carried out maintenance, I think it wouldn’t have worked in this mode for long, it would have overheated. Now the laptop is “breathing” and will hopefully serve its new owner for a long time. It will be possible to install a more vigorous processor, a larger HDD or an SSD.

Carry out timely maintenance of your equipment to extend its service life and avoid breakdowns. This is especially true for laptops, due to the limited cooling system, overheating is the worst thing for them. Spare no expense and purchase an additional cooling pad , this will also help combat overheating. I would be grateful for “like” the article and subscribe to the channel so as not to miss new publications.
