Q: Can the T590 be used with a 90W or 135W power adapter ?

Hi all,I have a T590 with mx250 GPU, and 65W power adapter. i 'm planning to buy a 90W or a 135w power adapter. So, I'm worried if it is compatible with my T590 or it will affect my laptop gradually and if the battery will get damaged gradually. Thanks

Hi I have just bought a second-hand lenovo W530 (with i7-3840QM quadcore processor), and it was delivered with a 135W power adapter. The seller tells me that the 135W one was the original power adapter for that computer. I would like to know if you know this is true, or all the computer were originally delivered with the 170W power adapter. As I would use the computer for engineering simulations I would like to be sure that the the computer have not CPU throttling due to the 135W power adapter when using near 100% CPU and GPU. Kind regards

Hi all, As my W510 was already experiencing thermal issues prior to this, so I stepped in to replace the thermal paste with the thermal Grizzly Kryonaut on the Graphics Adapter and the CPU. I applied a thin layer although it was slightly uneven, then replaced the components. When I tried re-booting, the computer got stuck at the bios screen and I powered it off. It now refuses to power up, and I hear a rather loud chirping sound coming from the attached 135W adapter, as if the adapter is powering on and off repeatedly. I have reseated the RAM and reset the CMOS but to no avail. Have I created a short circuit somewhere? Is my unit really dead? I would appreciate any assistance here. Thanks!

I Just got my W530 3720QM K2000m and i find it ridiculous that it cant use the 90W Adapter when idle and uses the battery. I Read threads of similar things with the W520, as well as some on the W510, and it appears that this used to work on the W510, 90W power adapter delivered the system in working condition with reduced performance. Now, i use my laptop as both a worstation and an entertainment laptop. if i were to go on a flight or be in a car, i sure wont be doing intensive VMware or 3d stuff, so 90W would be more than sufficient to drive the laptop as well as charge the laptop. i even have a Killawatt meter, i plugged in the 170W Adapter into it, and then ran my laptop while having the battery charged. the max power consumption that it pulled was 70W At the wall, surfing the web in optimus mode. Why cant we have a power saver mode to allow usage of the 90W adapter? or at least have the Choice between "battery only" - reduced performance anyways and "reduced performance AC/only"? At the very least it would avoid draining the battery for absolutely no good reason. My system idles at under 30watts anyways and that would leave 60W to do anything else, for example charging the battery at 40W - to give the total of 70W at the wall, from the 170W Brick. i Wish to see a revised bios to correct this or at least allow this. i dont believe its impossible or too complex to code. it was done on the W510, i dont see why it cant be done on newer, improved, smarter, more ...

A:W530 Power Adapters, 90W vs 135W Vs 170W

This topic has been discussed in this thread:  and this thread.  I have not seen a satisfactory reason why the notebook cannot operate from 90W in a reduced performance mode.  The conditions that cause a 135W power draw are rare. For light use my W520 draws 15-20 watts. As a thought experiment, consider what would happen if you had a 90W adapter attached, and suddenly the notebook tried to draw 135W.  The adapter would shut down due to over-current. This is exactly the same scenario that would occur if I unplugged the adapter while operating. The notebook is designed to instantly switch over to battery if the AC power goes away. So there is no risk to the computer. Maybe if the adapter is poorly designed, it could be damaged. I challenge Lenovo to provide a technical reason why the W520 and W530 cannot operate off a 90W supply in a reduced performance mode.  I believe a good portion of the 135W is for charging the battery. So if the power drain exceeds 90W, stop charging the battery. 90W should be more than enough to operate the notebook only under any circumstance. Under most circumstances, it can operate the computer and charge the battery.  This thread describes mods that will trick the notebook into thinking it has a different capacity power supply.

Yesterday I posted about the C2G docking station that Lenovo sells as compatible with the C940 (that's C2G Part# 28845).  Today I'm back with another USB hub with power delivery that has the same results.  This one is the Configear USB-C Hub from Amazon. Both of these USB-C / thunderbolt hubs will charge the laptop after first being plugged in.  That power delivery stops any time that A/C power is disconnected and then reconnected, or when the laptop reboots, and/or the laptop enters a low power state where it does not require the same power delivery (e.g. hibernation) and then resumes normal operation.  C2G technical support has no explanation for this, nor does Lenovo Premium tech support, nor any other technical support resource.  The only way to restore power delivery is to physically swap the thunderbolt port that's receiving the USB hub, but even that does not consistently resolve the power delivery connection.  It is also worth noting that while the power delivery fails, other connections via the hub work (mouse, keyboard, bluetooth headset, ethernet, etc.). Lenovo support suggested they could have someone come out and swap the motherboard, but I suspect this is some kind of firmware issue.  If you have a C940 and have had success consistently charging from a USB hub it would be great to hear about which hub your'e using.

Hi there,

We've got 3 Dell precision towers 5810 that work great, except for a possible bios bug, which I can reproduce on all machines:

I'm using the installed NIC: Intel ethernet server adapter i210-t1.
Our computers go powerless every night (mains power) after a normal pc shutdown. Every morning, when the power is back on, I want to wake up all computers in our building with Wake On Lan (WOL) by sending a 'magic packet' over the network.
This normally works well if the machine has been switched on and off with the power button / windows shutdown. But when I unplug the machine (mains power), wait and plug in the mains power again, the computer does not respond to the WOL packet. (Maybe the PCI-E NIC does not get power on plugging in the mains of machine for the first time).
It works well on the integrated (motherboard) NIC. BIOS / power / sleep state settings seem to be ok.

Hopefully someone here can help solve my issue, because I'm practically at my wit's end with it. I recently ran Lenovo's Updater program and it installed a few new things on my Laptop... I don't remember all of them, but I know one was a BIOS update, a Firmware update (can't remember specifically for what though), as well as a few programs I was missing on my computer (like Lenovo Power Management, just to name one).  It's something I hadn't ran for a good year, so I'm sure everything was using an older version! In any case, it seems after I did that, many of the games on my computer started playing worse.  Long story short, after checking out a few programs to monitor what my computer's doing (CPU-Z, and even Intel's Extreme Tuning Utility), I noticed that my Laptop's suddenly only using a portion of what it can do. For example, the core speed should be able to go up to 2.6ghz - 3.3ghz... but strangely, it's staying at a solid 1.20ghz the whole time. No matter if I run any graphic-intensive games or do anything else that might need some extra power, it stays exactly at that number. Here's the weird thing though.  If I unplug my Laptop and let it run off the battery?  It shoots straight up to the 2.6ghz-3.3ghz, as it's supposed to.  As soon as I plug it in again, it drops right back down to 1.20ghz and many of my games run like crap again. I've tried looking up solutions online, but I've found nothing that helps.

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

I just received my new X1 Extreme (replacing a Dell XPS 15 which was a disappointing return to windows after a couple of decades of macs). As is my habit, I wanted to get a couple of spare chargers to leave at the desks where I regularly use the machine. Strangely, the Lenovo website does not recognise the part number of the charger that came in the box and instead recommends a much larger one. I see a Lenovo 135w charger listed for other models on their site.  Will this one work? It's quite cheap which is good, but I am not familiar with Lenovo's rectangular connector or whether all their machines use the same connection and voltage. I also have a dell usb c charger, I am assuming this will work (dell rate it at 130w!) thanks in advance from a Lenovo newbie d

Check the label of your chargers, make sure the input and the output matches.e.g. For the charger of T460s:Input: 100 - 240V - 1.8A 50 - 60Hzthat's your socket voltage, some countries use 220V, and some use 110V. This charger accepts any voltage between 100 - 240VOutput: 20V 3.25Athat's how much power the charger charges the laptop. Any below that, the charger may be unable to charge the laptop (not enough power). Anything above that may damage the laptop (too much power)

Hi Another day goes by and more issues pops up with my brand new s740-15IRH unit. This time i am having issues with the battery not working properly.  I was running some games on my machine when i suddenly noticed that the battery percentage dropped from 100% to 99%...98%...97% despite the fact that the charger was plugged in with the system running in AC mode. The same time i noticed the battery drain i decided to shut down all CPU and GPU intensive tasks to see if the battery percentage would charge back up again. It didn't, it was stuck at 97% unwilling to charge back up so i had to discharge the battery and restart the computer for it to begin charging again.  I have tested this twice, same results. Is this something that's intended and configured with the laptop from the factory? Or is there something wrong with my unit? I'm running the latest battery drivers provided by Lenovo and all battery options in Lenovo vantage are disabled.

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message. My computer is from June 2006 and shouldn't be having this issue so early...or ever. This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue. I'm of course out of warranty, will Dell replace this free of charge?
 
`

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

This review in regards to the next Generation T series from Lenovo.  
 
The machine I tested is based on a Intel i7-8565U 8th Generation Whiskey Lake 1.8GHz quad-core CPU.  It came with 16 GB of DDR4 memory and a bright 14? QHD(2560 x 1440) with Dolby Vision 500 nit IPS screen.  The screen I got according to HWiNFO64 is Model LEN40AE with a Monitor name of B14QAN02.0. It looks to my naked eye as the same as my X1 Yoga 3 screen with Dolby Vision.  It?s a very nice screen. This screen does not support touch.  The side bezels have shrunk(see pictures below).
 
As for graphics.  It came with a Intel UHD Graphics 620 and Nvidia GeForce MX250 with 2GB GDDR5 memory.
 
For connectivity it came with 2 USB 3.1 Gen1 ports, 1 USB Type-C, 1 HDMI 1.4, 1 Thunderbolt 3, a MicroSD Card reader and 1 Audio Jack.  An interesting feature on this laptop that I personally have not seen before is the left side USB C port can charge other USB C devices.  It can output 5V at 1.5A. I personally have not been able to try this. The Thunderbolt 3 USB C port can also output 5V at 1.5A PLUS it can charge another laptop using P to P 2.0 charging function.  I was not able to test this feature either.
 
For Networking the T490 came with a Intel AC 9560 and mine came with a Fibocom L850-GL and Bluetooth 5.0.  It also included a Full size ethernet port.
 
For Docking it supports Thunderbolt 3 Dock, Side Mechanical Dock and USB 3.0 Doc... Read more

I connect  a Thunderbolt 3 Dock Gen 2 to my L390 Yoga with firmware 1.18 and the latest dock-drivers 10011. Then I try to make a firmware update of the dockingstation with firmware-version 3.1.61. After unpacking I start the "ThinkPad Thunderbolt 3 Dock Gen2_Workstation Dock firmware update.exe" with admin-rights. Then I get a the following warning: "Can't read Thunderbol controller version, Will skip Thunderbolt firmware update!". After clicking "OK" the updater continue until the next message appear: "Your dock has new firmware can be upgraded, please click [Update] to start firmware upgrade."  and the Current Version shows: = <unknown>.If I click the update-button the programm continue until the message: "Firmware update completed!" appear. A click on the OK-button close the update-program.If a start the firmware-update program again the same error happens. The update-program can't retrieve the current version of the docking station. So is the update-program buggy? The installed OS is Windows 10-1903 with latest patches and the docking with the 2nd usb-c connector from above on th left side. I bought the Thunderbolt 3 Dock Gen 2 because the Lenovo tool "docking-search" told me, that there are 3 dockings compatible with ThinkPad L390 Yoga. So what to do?

Hi, I'm trying to use my t590 under the new Fedora 31 linux and the experience is rather unplesent as for the fan noise goes. If there is nothing going on in the system then eveything is quiet so at least that's fine, but when the load starts to ramp up (browsing using firefox) the fan goes to maximu gear, spins as long as the the load persists and some time after (several seconds) and goes down to the lowest speed. Under Windows the fan is way more quiet and gradually increases its speed as the system load persists. Is there any way to make it behave like that under linux?

Is there a secret to turning on the ThinkPad T590. I just got it yesterday and I thought it was just a simple depress the power button and it comes on. It seems there is no rhyme or reason to just depressing the power button. I just opened it up and it has taken me almost 15 minutes and it finally came on.Yes, it is charged up.

Hi Guys I was about to order a p53s with an UHD screen howevere the UK website does no longer have the UHD display available as an optional extra. I read the T590 has a below average display. How does the display compare on the P53s as i cant find much info on its display. Thanks. I registered on the Lenovo Site. I got a discount code for 10% to my email. I see on the  website it is reducing the price automatically using a'pseriessave' code. Can i use both of my discounts together? nIts a bit of a con hading out discounts codes when they discount it on the website anyway.

Hi,I am wondering whether the Thinkpad T590's UHD 4K display makes use of PWM, accross all or any levels of brightness.I read that the FHD version had no PWM, so I'm hoping the same goes for the UHD.

I know this is a similar post to this one but that one is marked as resolved and I'm not so sure it is. https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/WinPE-driver-pack-for-T590/m-p/4520454#M... I'm having a similar issue. T590 pxe boots just fine, the MDT splash screen comes up but it fails to start loading the boot.ini settings and just sits there for about 20 seconds before rebooting. I am not able to hit F8 and bring up the cmd prompt.  I was getting similar results on the x1 carbon 7th gen until I got the WinPE drivers from here: https://support.lenovo.com/ca/en/solutions/ht074984 However, there are no WinPE drivers listed there for the T590.... I have downloaded the driver pack and added all of them into the winpe boot image just for testing purposes but it doesn't change the behavior. I've also read that this can be fixed by disabling the "Kernel DMA Protection" in the BIOS, however this did not change the behavior for me either. https://social.technet.microsoft.com/Forums/en-US/6930c036-e827-4579-bf38-64d6dd7113e7/mdt-wizard-do... Is there a reason that the T590 winpe drivers aren't available for download? It seems like a winpe driver issue to me but perhaps it isn't. Been struggling with this for the past few days so any help is appreciated. FYI - I am not using a docking station. Pxe booting with the ethernet cable directly plugged into the laptop.
