hi, ive noticed my new notebook is really slow. it has 8GB memory yet struggles to peform basic tasks like browsing.
i have ran "userbenchmark" which gives a really poor score for processor and graphics.
9.74% is an extremely low Desktop CPU score, this CPU can barely handle email and light web browsing.
2.22% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
its running windows 10 and the processor is Intel Core M-5Y10c
is there problem with my notebook or is it just a poor processor? thanks in advance

im not using for gaming. it struggles when watching videos on youtube etc. sound is choppy. i have enabled high performance mode also.
i upgraded from a windows 7 4 gb HP which is quicker than my lenovo. something doesnt seem right.
my CPU doesnt go above 50% is that normal?

yes same behaviour with/without AC
ive tried a few different benchmark tools and all are saying CPU and graphics are really poor
im still in warranty i will contact lenovo. i seen a post about a CPU throttle problem with some units and there was a product recall.

do you have a Yoga 3 or Yoga 3 Pro?
In case you have a Yoga 3 you might be experiencing what is described here:
Basically your CPU is stuck at small speeds (0.49GHz on my Yoga 3 11 with a Core M 5Y10c) and this explains why this is so slow. One way to get it back to normal is to turn off and back on with the charger plugged in (restarting does not work). Someone just suggested that hibernation might do the same. I have not tested it myself (yet!).
From what I understand: for thermal managements reasons the processor is turned down to this low speed (that probably comes from DPTF; some users have reported that it does not happen if you switch that off but that will most likely result in overheating) but does not get back to normal by itself.
Still waiting for a solution (bios update?) to come from Lenovo.
I hope that might help you to understand what is going on.

Disable DPTF to speed up Yoga 3 Pro Core M-5Y70 processor
Go to Bios and disable DPTF
(Dynamic Platform and Thermal Framework is a "solution to help enable thin, quiet, and cool platform designs". But as we can see it works awful)
Your laptop will be hotter, but it will work like a normal PC, capable of playing video on YouTube in Chrome 1080p 60 fps (on high performance mode, which you can choose clicking on battery icon in tray)
Frequency on high load drops to 0.5 - 0.8 GHz, CPU usage stays on 20-70%. Laptop slows down extremely and become unusable. Can barely play any youtube video, extremly slow.
Frequency on high load stays on 1 - 2.6 GHz, CPU usage up to 100%. Laptop works as a normal PC, never slowing down. The bottom cover of the laptop becomes hot.
also i updated bios, not sure if it works on previous bios version.
