Lenovo Recalling More All-in-One Desktops for Fire Hazard

By - Source: The Channel | B 16 comments

It looks like Lenovo's recalling even more of their All-in-One Desktops for overheating issues...

The Lenovo All-In-One desktops are elegant, sleek… and apparently fire hazards.

Due to overheating issues, Lenovo is recalling another 15,000 AIO desktops. In addition to the 13,000 that the company recalled last month, the total for recalled AIOs comes to 188,000.

Lenovo’s expanded the recall range date to be from May 2010 to March 2012. The recalled ThinkCentres were equipped with a faulty power supply that’s causing the overheating issues. For some, the overheating issue’s been so severe that two Lenovo customers have reported that their AIO’s caught fire.

If you happen to own a ThinkCentre M70z or M90z that fall into that date range, now might be a good idea to alert Lenovo. You can determine whether or not your M70z or M90z is eligible for a power supply replacement via Lenovo’s recall page on their official website, which details the entire screening process.

    This adds a WHOLE new meaning to "blazing fast"...

    Eh? Ehh?

    One has to question how these "All in ones" were tested. I think their is way too much emphasis on quiet instead of cooling. But I also have to wonder why the other safety features don't work? Such as the temp sensor on the CPU. I think their must be more to it then what Lenovo is saying. Apple has done "All in ones" for a long time, so has HP and Dell. None of which have had significant over heating issues and all use Intel chips.

    After reading the Lenovo recall notice. it seems the problem is more related to over heated power supplies. I guess they designed a little too weak on the PSU.

    That's what you get when you use $10 PSUs in your products, Lenovo.

    With this, Lenovo is now worthy of rivaling Nvidia.

    LMAO, I bet IBM is sure glad their name aren't on these any more! Come on baby light my fire!

    Seriously, you couldn't read a few paragraphs in the Tom's news article? They mention "power supply" twice. Maybe they need to TL;DR all their articles for "Today's Readers".

    TL;DR - Power supply make fire! Fire bad!

    They all do it. Outside of highend systems and boutique builds, all the mass produced OEM boxes use dirt cheap PSUs. The really bad part? The majority of these OEM junk boxes don't have any issues for years, so long as you don't add/upgrade anything that will tax the PSU more than stock components. Very little headroom, and generally not very efficient, even when they're otherwise dependable.

    CPU thermal sensor is irrelevant in a PSU failure. For the CPU to get hot enough to shut down a fire would have already started and become self-sufficient down in the power supply. same is more or less true for the mobo thermal sensor(assuming they have one). The thermal limits on AIO Desktops are already quite high, it would even further delay any automatic shutdown.

    As many others have pointed out Lenovo obviously used cheap and poorly protected power supplies. clearly very badly designed for them to catch fire before anything stops it indeed. Destroying a computer is one thing but risking homes, and more importantly lives is another. Especially odd for a respectable company like Lenovo.

    Quietness is important when a PC is 60cm in front of your face, which all-in-ones tend to be.

    not surprising, have any of you used an all in one? the are like radiators, particularly Appls's version, the heat coming from those things even at idle is surprising. Good if you live in a cold climate and need your room heated.

    I wouldn't expect anything more from the place that they were made in.

    I mean the PSU's for the rigs...... they're all made in..... and we have had our experiences of those PSU for a long long time.

    Sounds like these computers needed liquid cooling with fire extinguish failsafe.

    Not really, no. The motherboard chipset has lower thermal tolerance than the CPU. When the CPU gets hot, a lot of heat will dissipate from the heatsink, but the dissipated heat will reflect onto the chipset (Northbridge or single-chip, due to required proximity to the CPU), which itself generates less heat (so it needs lesser cooling - sometimes only passive) but also can't tolerate heat in response, and thus will alarm the motherboard thermal sensor often well before the CPU overheats, causing a system shutdown.

    Best advice with every computer is have it checked out by a trained technician to disassemble and have your fans and heatsinks cleared from dust, lint, pet hair, smokers tar, etc., before it gums up your fans and blocks heatsinks. If your fan bearings are already rattling, it's likely already too late, so you'll need to replace those fans. Have it checked AT LEAST once a year, although some people need to have it checked once a month if they live in filth. If you can do it yourself, be my guest, but don't procrastinate. It's required maintenance and needs to be done.

    Oh and CHANGE YOUR DAMN FURNACE FILTER! I see too many people that have pet hair and dust hanging out their filter insert because they don't change it regularly, and that's just gross! You should check it at least once a month. And make sure you put it in the right way around. If you have the cheap Walmart filters, replace them every other month. This is just general health advice, but cheap filters let lots of dust through, and it's bad for your computer, as well as your lungs. If you use central A/C, don't forget that it still works through your furnace vents, so it's still blowing dust through. Having your vents cleaned by a professional cleaning service once in a while doesn't hurt either.
