Old Ideapad N581, how to protect from Meltdown and Spectre

Hello everyone,

 

in 2013 I purchased the Lenovo Ideapad N581 and I am running the newest version of Windows 10 with an SSD. The speed is incredible and I want to keep this laptop for as long as possible. 

 

But with the recent meltdown and spectre debacle, I don't know if I am safe. I heard that I have to update the Bios, but there is no support for Win10.

 

What do I have to do to protect myself? Do I have to buya new laptop? Is an update of windows really enough?

Re: Old Ideapad N581, how to protect from Meltdown and Spectre

The impact depends in part on what CPU you have. That one comes with both Intel and AMD - only the former is liable to be compromised by Meltdown, and is also quite heavily impacted by OS patches (but it may be faster to start with). Both are theoretically vulerable to Spectre without BIOS patches to go along with the Win10 updates.

To be honest if you keep your OS and web browser up to date and don't download shady software, you're likely to be OK. Neither Meltdown nor Spectre magically allow things to run on your computer - they just mean that things which *do* run might be able to leverage that into greater access than they should have.

Yes, I have an Intel chip.

So there is basically nothing I can do to close it, other than staying safe on the net and update my programmes.

 

To be honest, this doesn't sound too good.

Hello,

 

This is a reply to someone I gave with a different model, but in a similar situation:

 

https://forums.lenovo.com/t5/Security-Malware/BIOS-updates-for-Meltdown-and-Spectre/m-p/3945092#M307...

 

Does that help answer your question?

Thank you. That was very helpful.

 

Any idea on how the patching will work? I mean do I have to install it manually? When do I know that my CPU is getting the patch and where do I find the patch, when it releases?

 

Again, thank you very much.

Hello,

 

I would imagine any updates would be shipped using existing mechanisms, like Lenovo System Update for older versions of Windows, the Lenovo Vantage app for Windows 8 and 10, and direct downloads from Lenovo's support web site.  For System Update and Vantage, they'll automatically identify the right patch to download.  For going to Lenovo's web site, you would need to look it by your machine type and model, and go to the appropriate download page for the update.

Note also that Microsoft may be deploying microcode patches even if a system is out of support on Lenovo's end, though I imagine they will want to be 100% sure it's solid first (and the older the system, the lower down it is on Intel's own priority list - Microsoft can't provide microcode that doesn't exist).
