Why doesn't my computer work until it's warm?

Jerry from Alexandria, VA

Episode 1288

A friend gave Jerry an old laptop that doesn't work very well until it warms up and he wonders if the power supply may be dead. Leo says it's possible. It's also possible that some of the solders on the motherboard really don't work well until the computer heats up and it seats the solder connections better. That was very common in the early years.

Dick DeBartolo

This week's gadget from the Giz Wiz is the Weems and Plath SOS Distress Light! It's the first and only LED Visual Distress Signal Device that meets U.S. Coast Guard requirements to completely replace traditional pyrotechnic flares. Unlike traditional flares, this electronic flare never expires which solves the big and annoying challenge of flare disposal. This floating electronic flare can be hand-held, tethered, or hoisted aloft. It's visible up to 10+ nautical miles and lights for up to 60 hours unlike traditional flares which last minutes or less.

Why can't I wake up my PC?

Jeff from Aliso Viejo, CA

Episode 1287

Jeff upgraded Windows 10 but his password doesn't work when his computer goes to sleep. He wakes it up and it won't unlock. But he can put in a random password and it works! Shut down doesn't work. Leo says that Caps Lock, Num Lock or Scroll Lock can be accidentally hit and it'll lock him out because he's not actually typing it correctly. Restarting will reset the state of the locked buttons. Leo says just to start over and re-upgrade. But since it's a new computer, it may be wise to just return it and get a different one. Something is flakey.

Why does my computer keep losing access to my hard drives?

Bill from Glendora, CA

Episode 1285

Bill's hard drives keep disappearing from his computer. After he reboots, it'll say "fixing disk," and will be there for about 10 minutes before it disappears again. His SSD boot drive works fine, though. Leo says there are a lot of things it could be including hardware and cabling. He should go and look to see how its setup in BIOS. It should be something wrong with AHCI or a driver issue. Since he built the computer himself, there's no one he can call for help. Then again, the support from the major companies isn't helpful anyway.

Can I test the signal strength of an HDMI connection?

Episode 1286

Jay from Providence, NC
Monoprice HDMI signal tester

Jay wants to test his HDMI signal strength because he can't use his Mac with his TV. Monoprice has an HDMI tester. Leo thinks it's more likely a cable compatibility issue, though. He'll need to have the most recent HDMI spec and if his Mac is too old, that could be the issue. Apple doesn't want to really support copy protection issues.
