Can I replace my laptop's CPU?

[effable]

Hello! I have a Lenovo IdeaPad Yoga 2 Pro with an i7-4510U

It's quite old and it's been really slow. I've optimized it, reset it, restarted it, ran virus scans but nothing.

Would it be possible to replace it with an i7-7700HQ or some other good i7 that will go into the laptop? (if possible I want one that has a good amount of power and is like 6-7th gen.)


Thanks!

No, you cant get a 6th or 7th gen CPU for that laptop. You may be able to get a better 4th gen i7, but the performance boost would be minimal, the CPU would not be easy to find, and it may not work.

Oh.. Is there anything I can upgrade for a better performance?
Money is tight and we can't afford a new laptop so is there anything I can do?

That is an ultrabook, there is not much you are going to be able to do to it. What are you trying to do with it that it cant do? It is not a terribly old laptop.

It's my mom's. She uses it for facebook, email and just her studies.
She has no more then a few tabs open like her email, youtube, facebook and a few pictures but it barely holds up. It lags a crap ton and I've done everything possible.

Have you monitored temperatures at all? Possibly running hot and cleaning off whatever junk they put on there and using some high quality thermal paste would help.

It's not a crazy fast CPU, but should breeze through browsing perfectly fine.

If it is running hot, I would recommend Themral Grizzly Kryonaut, could end up being a $10 fix.

Cpu and ram are soldered. The only thing that can be changed is the ssd. It shouldn't be lagging with just that. My first thought was it was overheating as well. Check the temps. If that's fine, check to see if the cpu speed is going up with cpuz. How much ram and usage?

 

[Peter Martin]

Updates can render an hdd useless in those. An ssd is the way to go if temps are ok.

Yeah, the laptop get's extremely hot within 10 minutes of basic usage. Could that be it?

 

[k1114]

You need to check actual temps to make sure. Ultrabooks could use the case to help cool so it feeling hot isn't a sign of overheating. Use something like hwmonitor.

Most certainly is the cause would be my bet, are fans running? I'd go ahead and replace the thermal paste. What temps does it actually read? Regardless it shouldn't feel that hot to the touch from basic usage after a few minutes, I doubt it did when it was new.

I don't know what anything means, but I took 2 screenshots of hwmonitor running.

80c isn't hot enough for it to throttle and the speed is showing that it's going up to 3.1ghz. 55c idle is high but it might have a setting to stay quiet and keep the fan off. Does the fan stay on all the time?

What is the ram usage?

 

[izoli]

Is this at startup or after its been browsing for a little while? if it's at 55c right away for a minimum temp, that is hot. 81c is not hot enough for a maximum temp to cause throttling, but if thats just sitting at idle during startup then thats very hot and will likely reach throttle temps under any sustained load.

^ ram usage (only chrome is on)

idk anything about the fan

Those screenshots were after 15 minutes of browsing.

If things are running slowly while browsing, it may not be a hardware issue at all, but rather, a network issue. Have you run a network speed test?

I literally stated the PC glitches out etc.

My speeds are 20/1 and can handle anything just fine.

I just looked through this entire thread and not once did you say that the laptop glitched out.

OOF, sorry, I stated it's slow in general up there.

my mistake e.e

 

[k1114]

Was it lagging before the screenshot? I'm suspecting it's the ram usage that's the issue. It's already compressing ram and starting to page. If other stuff is open, it would be paging a lot more. What's the ram usage with nothing open?

 

[izoli]

should definitely not be using 6GB of ram with just chrome open. got any sketchy extensions on there?

 

[effable]

No extensions at all.

 

[izoli]

What does task manager show as using all that ram?

What antivirus and other startup programs do you have on there?

 

[effable]

Malwarebytes premium, disabled all startup programs
