Are mesh routers good for Ethernet connections?

Episode 1374

John from Santa Cruze, CA
Eero

John has an TPLink Archer C7 router, but he wants to know if a mesh router would be able to support adding ethernet to it. Leo says yes, it can. They're expensive, but the advantage is that he can connect to ethernet anywhere and it will handle it. John is wondering if he gets an access point to add onto his existing router, would he have two separate network names, and would he have to manually switch to the closest one? Leo says he can just name them the same, and it should work OK.

Jeremy from Ventura, CA

Episode 1373

Jeremy has a Lenovo 11S and the power supply died. So he replaced it along with replacing the motherboard. It runs great, but he'd like to increase the RAM as well. Leo says it depends on the motherboard and the amount of room inside that laptop. Leo says it's odd that he was able to replace it. Laptops are highly customized, so that is likely a problematic endeavor. Laptops tend to not be upgradable by design. Jeremy can check with crucial.com and kingston.com.

How can I get my laptop to turn back on?

Episode 1370

Anna from California
Sony Vaio laptop

Anna has an old Sony Vaio laptop that won't turn on anymore. Leo says that the battery may have finally died. Her laptop is pretty old and the battery may not be able to keep a charge. She should try taking the battery out and see if the laptop will turn on with the AC adapter. If it can't, she may need to get a new battery for it. They're about $90. That's a lot to spend on an old machine, though.

Can I use old RAM in a new laptop?

Episode 1366

Greg from Redlands, CA
RAM

Greg is looking to buy a new laptop and wants to know if he can still increase the RAM after he buys it. Can he plug in the RAM he has in his old one to boost the RAM of the new one? Leo says probably not. The form factor needs to be the same, and in most laptops the RAM is soldered in. He may be able to if it's SO DIM compatible, but then there's the speed issue.

Greg should go to Crucial or Kingston and use their RAM Picker to see what he'll need. If it comes up with something similar, then maybe it'll work, but it's not likely.
