K8 Note Left Speaker Not Working

Legion Y740-17ICHg laptop [technical charging issue]

I’m aware this is a built in feature to preserve the battery, however I’m still searching for any possible way to disable this feature. Here’s the issue, the laptop is plugged in not charging (over 95%), i’m trying to play game, if i unplug and plug it in, it’s still not charging, the laptop will essentially freeze the battery percentage between 95-99%. When I turn in on, the laptop is always at 100% because i leave it charging, this has become a constant problem for me because the games I play wont run on battery power without lagging, how can i fix this without unplugging the charger and waiting for the battery to drain 5%, it’s just so annoying to have to do that every time I use my laptop… terrible feature for a gaming laptop.

Yoga 730-15IWL – Thunderbolt 3 PCIe Lanes & Specs (PCIe x2 or x4?)

I’m considering purchasing the Lenovo Yoga 730-15IWL (no. 81JSCTO1WW) as it has the latest Whiskey Lake-U CPU and one Thunderbolt 3 port (TB3), which I want for eGPU expansion in the future. (This model can be customized to have a NVIDIA GTX 1050 4 GB.) However, I would like to know if anyone can confirm whether the TB3 port on the 730-15IWL supports full PCIe x4 speeds and not x2.


Ultrabook Review states that the Kaby Lake version of the Yoga 730 (730-15IKB) only supports PCIe x2 over it’s lone TB3 port, but this isn’t the model I’m concerned with since I like the Whiskey Lake version (730-15IWL) for its newer CPU.  MyFixGuide lists the Yoga 730 15" as having a x4 TB3 port and also matches the specs of my model of interest (i7-8565U Whiskey Lake-U and GTX 1050). This makes sense, since the i7-8550U (KBL) only supports 12 PCIe 3.0 lanes, while the i7-8565U (WHL) supports 16 lanes, and should be able to spare 4 lanes for TB3.


Some users have found the Yoga 730 15" to support only x2, but that post seems to be limited to the Kaby Lake-U model (based on the schematic). Another reply says the 730 15" can support 4 PCIe lanes. I would really appreciate confirmation that this custom Whiskey Lake-U model does in fact have full TB3 @ x4 bandwidth for optimal eGPU use.


In addition, it would be nice (but not as important as having PCIe x4) to be able to charge & plug in a TB3 peripheral. Some other forum users (1, 2) noted that the 730 15" does not support charging over the TB3 port, but perhaps that’s only with the 15IKB and not the 15IWL model.

Here’s the configuration I’m looking at:



Legion Y520 Upgrade

Hi, I have a Legion Y520 i7-7700 4GB DDR4 SODIMM 2400Mhz. I am planning to upgrade the RAM to around 12gb and was wondering what kind of RAM i can use. The manufacturer website states any one of these will work: 


DDR4 2400 4GB_Samsung 01FR300

DDR4 2400 4GB_SK hynix 01AG708

DDR4 2400 4GB_Ramaxel 01AG701

DDR4 2400 4GB_Micron 01AG709

DDR4 2400 8GB_Samsung 01FR301

DDR4 2400 8GB_SK hynix 01AG711

DDR4 2400 8GB_Ramaxel 01AG702

DDR4 2400 8GB_Micron 01AG712


But i was wondering if i can use any other DDR4 SODIMM 2400 RAM e.g corsair or Kingston. Is it better to stick with the recommended or do other RAM types work?

Broken stand resistance in Lenovo Yoga Tab 3 Plus

Anyone know of a good way to fix the internal stand holder that keeps the kickstand held in place at any position? The one in my Lenovo Yoga Tab 3 Plus is broken, and as a result the stand only holds at one rather unstable position.
