Lenovo W510 with 90W adapter - Reduced Performance

Q: Lenovo W510 with 90W adapter - Reduced Performance

When using 90w adapter with Lenovo W510 the performance is reduced even when the system shows low power consumption (40W). if you switch to battery - strangely, the performance improves. It is understandable that the performance will be limited (reduced CPU and GPU clock speed) under 90w power supply (to protect the adapter) but it shouldn't be limited immediately. if I watch a video it doesn't really work with the 90w travel adapter (very very slow) - then I take the power cord out and WOW everything works fine... The bios should be fixed so that the clock limit will kick in only when the power consumption goes up. otherwise, when you travel with this expensive machine you have to either carry the super heav y 135w adapter or get a performance of a net book.... Does anyone know about a fix?

Preferred Solution: Lenovo W510 with 90W adapter - Reduced Performance

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi! It is really annoying, I set up in windows performance in power option fo 100%,  turned off intel speed step, and when I am running windows 8 (on windows 7 was the same situation) on battery Core temp 1.7 shows constantly 1,7 GHz but when I plug the cord processor speed ranges between 1.2 up to 1.7 and I can see decrease of speed on youtube when I am watching full hd movies for example even when I run Prime95 and fully load the processor speed changes between 1,2 and 1,7 Ghz , on battery is 1,7 all the time . Does anybody have idea what is wrong or what should I do ? thanks

I have had my Lenovo w510 for 2 months with 16gb of RAM running an i7 chip. I am really unhappy with the performance. Given the horsepower, it is really slow and hangs a lot. My previous T61p was faster and more relaible. Both Laptops have the same corp image + I have downloaded every patch from the Lenovo website. Even as I type, the words are taking their time to display!!!! If anyone has any bright ideas on what to test, please let me know + is there any decent software that tests for possible bottlenecks??

This is certainly not normal. Mine has half the RAM as yours and is very fast.

Maybe its my inagination (but I don't think so) My w510 seems to slow down a lot on battery power. I know that running a 90w power adapter will cause the system to slow downk, but I would think that the battery would still be able to keep up.I end up with a little under 2 hours run time when on battery - everything says that it points to a healthy battery. Was just curious if there was a optimized setting for the w510 to get peak performance on battery. Thanks !

I have seen this screen several times during the startup. Does it mean I need to get a new adapter now? Is it the cause to make my W510 performance (Windows Experience Index (WEI)) as low as 2.1 (https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/why-my-W510-with-12GB-memory-and-SSD-has...)? thanks

Just guessing, you probably have a quad W510 and are not using the 135W adapter but a 90W or 65W model...
(Or the 135W is indeed defective....)

Hello guys. Recently I've bought I PowerColor ATI HD 6790 1 GB DDR5 video card. My old one was the 4670 version, though it was from Gigabyte. And oddly enough, my performance seems to have been reduced.

This is my current setup

AMD Athlon(tm) 64 X2 Dual Core Processor 5200+
PowerColor Ati HD 6790 1GB DDR5

I've had a lot of reduced performance with my system lately, in addition to a lot of windows error messages for some reason. I just un-installed a handful of anti-spyware/malware apps because I had way too many.
Now I'm left with HJT, MalwareBytes (w/ active protection), TuneUp2009, ZoneAlarm, & Spyware Blaster
Is this sufficient protection?
Applications load up much slower and the start is lagged.
Otherwise I haven't had too many issues, a couple crashes few and far between.
Any ideas?

It takes about ~4 mintues to boot this laptop, inexplicable CPU usage. Though the usage isn't consistently bad. Today I experienced such taxed resource usage, that simply moving the cursor across the screen had a choppy latent effect. I'd move the cursor, and about 1-2 seconds later, it would move it's position on the screen. I have ran Ad-aware, and Spybot, and they removed only tracking cookies.

Cry Performance reduced after reinstalling WinXP pro

I have just reinstalled my system (XP Pro) and updated it online to SP2. Authenticated updated and all. I haven't changed any hardware and in fact I reinstalled less software than before.
Since reinstallation and updating, I've noticed considerable deterioration on system performance, reflected e.g. on scroll speed (eg in Firefox and in Word & Excel. For firefox I've checked "smooth scrolling" it's off. Especially Word used to be up to 1page/sec while scrolling with arrow keys, now is down to 5-6 sec/page. Also: normally Word shows the page numbers (lower left corner) changing as you scroll - not anymore in my case. Page numbers remain change only after scrolling stops. Other example is when I move windows on the screen, movement is not spooth but rather jerky.
Any ideas?
My 2.66GHz machine is clean according to avast antivirus, spybot, adaware & adwatch, Netscape's own spyware scanner. Reg mechanic finds no problems. HD (40GB) is error free and cleaned-up and defragmented. Smooth scrolling options are off.
Thanks to anyone who could help.

A:Reduced performance after reinstalling XP

Help with MS Office is another forum, so I can't hep you with Word settings.
As far as your general slowness issue: If it's slower now than it was before the re-install, then you did something different this time than you did previously. Try and think what that might be. I could sit here and guess all week and we might never stumble across it, there's just too many things that could affect performance.

I have purchased a gaming laptop in august of last year and it has been about 11 months since I've got it. For the first 8 months everything was amazing, i was getting high fps and good performance on all my games. Then about 3 months ago, the performance
went dramatically downhill. I wasnt sure as to why this happened so i restored my whole laptop but to no effect.
Any ideas? Anything helps,
Thank you.

Week ago I bought new SSD drive. (OCZ Agility 3, 2.15 firmware)
I made fresh install of OS, newest drivers etc.
SSD and my system was working very well but I was disapointed to my SSD-benchmark results. Well I tried to increase performance by updating my motherboard bios. Bios update succeed but it didnt really increase performance of my ssd, new bios reduced writing performance notable. (MOBO = Asus m4a87td/usb, bios v.2001) AHCI is on.

What with that 103424? Shouldnt it be 1024? Previous score over 400 points, now just 300. (disappeared in picture)

Also noticed another problem. I can't boot my comp if I have external drive plugged in.
I just can't change my 1st device boot to agility drive in bios because it's not in the list of boot devices. Well I unplug external drive and its working. Also thought that bios update would fix it but it didnt.


A:SSD Performance reduced after BIOS update.

Your numbers are lower than most, but I don't know if it would be noticed in real life as opposed to a benchmark.

I think that 103424 is a reference to alignment. If it's evenly divisible by 4, it should be OK--and it is.

Not sure about the BIOS/external drive issue. Was the external connected when you did the clean install to the SSD?

One way or another, I'd make sure all boot files were on the SSD and that it appeared in the BIOS and was bootable, regardless of whether the external was plugged in.

I am reasonably computer-literate, at least to the point of maintaining an efficient and virus free computer to operate at top performance. Inexplicably, my gaming performance on applications which normally achieve steady frames in the 40's and 50's range are completely stuttering around 2-3. My computer is very well maintained, with a commit charge of 123, regularly defragged, registry cleaned, scanned for viruses, etc. I thought that it might be a case of conflicting drivers, and as such updated all of them, with the exception of my BIOS (was going to try but am out of floppy disks). The only other thing that I can think of besides a BIOS conflict is that in the add/remove programs list is a Client Hack 1.9.2d that cannot be removed, nor is it recognized when I do deep scans with kaspersky or bitdefender. it seems unlikely to me that one virus is drastically reducing my gaming performance, its possible that a particular setting on my computer is wrong, but I checked everything I know (including BIOS AGP aperture settings, etc). Please, any assistance would be GREATLY appreciated, as this has been driving me mad as I've been trying to remedy this on my own for the past few days.

This problem has me completely baffeled. I'm not even sure if this is the right forum to be posting in. (If you can suggest a forum better related to topic please do).

Recently I noticed my whole system being slower and more sluggish. Especially playing games. I checked my windows experience index and it had changed from 6.5 to 2.9.

The only scores in the list that have changed signifigantly are my cpu (now at 2.3) and my memory access(2.9).

This happend to me once before about 6 months ago. In the end I updated my dell bios from a10 to a11 and my score went up to 6.5 and my performance was percieveably improved.

Now I dont understand why (what seems like the same problem) has happened again.

I'd be very grateful if somebody could help me figure out why my system has suddenly slowed down so drastically.



A:CPU and memory performance suddenly drastically reduced

Take a look at Task Manager when it is running slow. Look at processes to see what is taking up RAM and CPU cycles.

Does it boot as quickly as before?

I wouldn't expect a BIOS change to improve things.

Look at Resource Monitor to see how much RAM you are using at any particular time.

Have you done any tests of your RAM or hard drive to confirm they are OK?

How confident are you that you have no viruses or malware?

Hi Team
Ive an older notebook that i still use when needed, but recently it has become  increasingly slower and slower and very temperamental. By this it can take a load of time to load up a page, or any simple task can just hang, to the point i will go start making a coffee! It just seems to some days really struggle to do anything.Whilst not the fastest notebook it has saved my bacon on a few ocassions, i would like to keep it as a spare but dont know why its all of a sudden having issues.
The notebook is a Operating System is a Windows Vista Home Basic 32-bit SP2 running an Intel Celeron M @ 1.86GHz Conroe-L 65nm Technology, its RAM consists of  1.00GB Dual-Channel DDR2 @ 266MHz (4-4-4-12), the Motherboard is a Acer Volvi2 (U2E1) and the Hard Drives is a 75GB Hitachi HTS542580K9SA00 (SATA).
The hard drive has been partitioned by the previous owner i assume, as i certainly didn’t do it. It looks like the following

A:Acer notebook performance dramaticly reduced recently

Yes, low free space on the C drive is a problem here. Experts recommends at lease 15% free space in the OS partition for proper system operation. Other than the free space issue, there might be additional problems in your system such as malwares, failing or old aging hard dive etc. Please try the below steps.
Transfer all the data that can be moved from C to D partition. Free up maximum space as you can. 
Download and run TFC to clean all kind of temp files.
 Uninstall unused applications.
      Open Control Panel --> Programs and uninstall all the software which you never used. They only help to eat hard drive space and slowing down Windows by adding unnecessary services.
To detect and uninstall bloatwares pre-loaded by laptop manufacturer, you can use the free program PC Decrapifier.
 Use Microsoft Security Essentials as the antivirus solution.
      Most of the third party AV programs are huge resource hogs and known to slow down  systems. Microsoft's own AV program MSE requires very low system resources and works very well with Windows. I highly recommends uninstalling your current antivirus completely and use MSE instead.

I have a DV6 Hp Pavillion laptop, which was working perfectly up until a few days back. Even though it is a little old, because of my 8GB RAM , 2Gb ATI Radeon and i7 Sandy Bridge it was functioning efficiently until now.
I replaced my battery and charger a year back. The laptop was was also replaced about 2 months ago.

In the last 1 week, I have noticed that my laptop is always heated and overheats even when I play any low graphic games .This I presumed was because of a battery/power issue which caused the laptop to lag/hang. Henceforth, I ran an energy diagnostic test on my system and came up with the follwing results (I will post them below this paragraph).

So, I'm at school and I receive a text from my mother stating that she is receiving porn popups and that google results are sending her off to random pages. This isn't uncommon because no one in my family understands computers anymore than your average secretary (no offense, but let's be honest. lol)... That being said, I went over and ran a few scans as I normally do which tends to clean it up fairly well. I begin by running HiJackThis and looking through it's logs and then looking at the startup items...

During this processes, I noticed several suspicious files that definitely did not belong. I then made sure to update the definitions on the current AV installed (BitDefender) and ran a scan with it. Afterwards, I continued to run Malwarebytes AntiMalware and SuperAntiSpyware. All 3 of them came back with results of finding several trojans... After running those, cleaning with them, rebooting, ect.. The popups were gone and the system was operating much more smoothly...

However, I got another text 2 days later, after returning to campus, that she was getting redirects again and BitDefender kept popping up several alerts about trojans... For insance, when I used that machine to google GMER; it showed the proper results but when clicking on the first result it then redirected me to:

I should also note that ComboFix results in a BSOD everytime.

While you may see ComboFix being used quite often, and possibly you have used the tool yourself without incident, the tool should not be run unsupervised (as stated in the Disclaimer that is first displayed by ComboFix when you run the tool)

Going forward, I highly recommend you heed such instructions. As explained in Post 2 of our pre-posting topic...


Why we don't ask you to run ComboFix from the onset

ComboFix is a very powerful tool which when improperly used may render your machine to a doorstop.

We first need to verify if there's any rootkits present and how they could affect our tools. DDS & GMER are preliminary scans. We use their logs to map our strategy for attack.

With these logs we can determine the infections present & decide whether to deploy ComboFix.

That being said, I'll need a log from another tool. Again, it's important you follow these instructions as given.

Please download aswMBR.exe and save it to your desktop.

Double click aswMBR.exe to start the tool. At this time, select No when prompted to download the Avast database.
Click Scan
Upon completion of the scan, click Save log and save it to your desktop, and post that log in your next reply for review. Note - do NOT attempt any Fix yet.

It shows no error message and no reason as to why it slows down that I can tell. Device manager shows no problems. Desktop is also ran on wireless through a different adapter and never loses speed, so I'm fairly certain its an adapter or windows problem with the laptop. I've tried original driver and updated to most recent driver and still does this. I've turned off automatic update of driver in Win8.1 also.

Any help would be appreciated.


A:Wireless Adapter Reduced Speeds

There is a long list of firmware updates that relate specifically to Windows 8 for your Asus RT-N56U router. I would suggest you update the firmware.

ASUSTeK Computer Inc. -Support- Drivers and Download RT-N56U

It also doesn't help when the modem is a gateway or a modem/router but the only requirement there would be to turn off DHCP on the N56U, although I don't see how this could create the problem you are describing.

A:Lenovo W510 Processor Upgrade

Welcome to the forum!
I was of the opinon your W510 will only support 1st generation Intel Core i7 models. Meaning you could upgrade to one of these CPU's:

Intel Core i7-820QM, 1,73 GHz bis 3,06 GHz, 8MB
Intel Core i7-920XM, 2,0 GHz bis 3,2 GHz, 8MB

 I want to upgrade the memory on my Lenovo W510. It currently has 8 GB total and I want to get it up to 16GB. Currently there is 4GB inside under the keyboard. I only found one slot there even though its supposed to have 2 there. The other 4GB is on the underside of the unit. You can see from the photo that the 4GB is installed on the left side. The right side is also supposed to house a memory card but there doesn't exist a holder for the memory card on that side. So basically I have two slots that are usable. Can I just switch the 4GB card with 8GB cards to get to my 16 GB?    No slot holder on the right

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!

Hi! I replaced the plug cable but laptop recognize power supply now not as 135W, I think owing to the replaced plug cord. Original was thicker. Anyway could somebody measure the resistance between ground and signal pin ? I have read somewhere here that making short circuit between ground and signal pin making power causing charger recognizable for laptop as 135W . could anybody confirm that before I damage laptop ? thanks

Dear TSG & co.

I've been working on a huge doc in word (w/images)... Since it has grown (78 pages = 14'600kb), problems.

1) Track-changes was activated by default; seeing this as a potential source of problems, I deactivated in word. However, evertime I save and then open doc on another pc, the track changes reappear & doc is increased to 100+ pages of text & images. I believe this has blocked my pc (ASUS pro5di, windows 7, Office 2010) and corrupted or lost data.

Since starting with this doc, I realized that every time I create a new word doc, it opens as a very narrow page on the left side of the screen. It isn't the zoom: zoom was at 100% and when I increased it, I had to increase to over 200% to read any text.

Any ideas?

Is their anyone on this forum who knows of a good program to test the performance of a video adapter and test to see if it is working correctly. Preferably one with diagnostic capabilities.

Any advice appreciated.

A:video adapter performance

Any number of diagnostic programs can test your video adapter, but you may have difficulty finding one that'll test it thoroughly. Programs such as Norton and Nuts & Bolts do a cursory test and don't really put the video through it's paces very much. You may want to run a simple directX diagnostic to make sure it's up to snuff for games that need directX. You should find a program called dxdiag.exe in your c:\windows\system folder, or your could run a search for it by typing dxdiag in "find" on your start menu. The program icon is a big yellow X on a blue background.

If there's a good utility to do what you're looking to do, someone here will know, they're surprisingly resourceful!

So I have a 6 day old Omen 15. It is a wonderful machine however when I boot up and launch chrome, I get a message stating my pc could potentially be running reduced performance due to underpowered AC adapter. The message is more detailed, but that's the gist of it. Also, I upgraded BIOS to F08 due to flickering screen which was resolved with BIOS update. However, if the message is true I will likely return the pc. Selling a high quality pc with an underpowered AC adapter is unacceptable. Any insight on a correction? Any help is appreciated,Cory

So a few days ago I got my PC, after plugging everything in I realised my monitor uses a VGA cable which isn't supported by my graphics card,so I used a VGA to HDMI adapter and plugged it in. I realised my resolutions are messed up, it shows more resolutions than it should ex. 1440x900(native) but I can go all the way up to 1920x1080 which my monitor can't support, even though I'm on my native resolution, everything looks bad quality, it's especially visible in games, I literally have to turn anti aliasing to the max for it to look playable, but here is the worst part, I have performance issues, fps drops and overall bad performance for this gpu and cpu combo, looking at some benchmarks on YouTube I see a pretty big difference in performance. I don't know what to do and is it because of the monitor or am I just missing something?

Ryzen 5 1400

I recently updated my Dell m4800 to BIOS A8 with Windows 7 64. I had been using a collection of older power adapters from my previous Dell m4400 without any issues. After the update, wow. A huge performance hit if I do not have the 19.5 volt and 9.23 amp adapter connected.
The m4400 power adapter is 19.5 volt and 6.7 amp. Pretty close right? Not any more.
I do have it connected to a Dell docking station almost all the time. Just checked. They are both 6.7 amp.
Anyone know what changed in BIOS A8 and what the deal is with the performance? Looks like I need to request a new docking station, but I'm not sure IT will believe my story.

A:Slow Performance without proper Power Adapter after BIOS A8 update on M4800?

I'd like an explanation from Dell as well.
If I'm correct, the crippling started with A07. I have the i7-4900MQ CPU with "Max Qualified Speed" at 2.80 GHz (multiplier 28) and "Max Turbo Boost" speed at 3.79 GHz (x38 ratio). Independent of the BIOS version (A06, 07, 08 or 09), when on the 180W AC power adapter, the CPU runs at x36 ratio i.e 3.59GHz. Even without any processing load. The same goes for battery power, whatever the BIOS version, the CPU speed is at x 34 ratio i.e 3.39 GHz. Again, without any load. On battery power the CPU is at a higher speed than the "Max Qualified Speed" without any need for the Turbo Boost.
Now the problem arose with the version A07 and exists in all of the following versions. When you plug in an adapter which is less than 180W, I have several of the 130W ones, the CPU multiplier drops to 8 which is the absolute minimum and makes up 800MHz. Ridiculous! Right after you remove the power supply you get an immense 3.39 GHz, over 4 times the speed when on AC.
As I need to use the laptop on a dock which has the 130W power supply weekly, I've reverted to BIOS A06 first. The computer is unusable at 800 MHz, it's like going 15 years back in time. The most noticable feature of the newer BIOSes that I like is that they somehow optimize the fans and make them quieter.
Does anyone if there is a limit on how many times the BIOS chip can be flashed?
I'd like Dell to explain why they have made such a move. And ... Read more

I'm curious to find out if there's any computer performance advantage to using an HDMI cable to drive an external monitor from my laptop VS driving the external monitor via VGA cable. Also, if I set the color depth setting to 16bit instead of some higher value, seems like that should speed things up, etc.

Can you recommend a good software that can let me see what differences there are in computer performance as I vary these settings?
