i read it somewhere.. maybe it can be use? just a suggestion

i need help here. my lenovo y480 has a problem with charging. Here's the details :

1. i plugged in the adapter to laptop.
2 it was ok for 2-5 minutes.
3. then the power button and battery indicator on the laptop keep blinking.
4. it was discharged.
5. i had to unplug and plug again to charge, but then it happened again.

What could be the culprit? Thanks.

Hi guys. Thanks for replying. i think i've found out the problem.

Apparently, the power adapter is the problem here. I noted that my power adapter output is 19V - 3.42A which is only HALF of the output supported by lenovo y480 ( 19V - 6.15A ) . This is why whenever i'm using power hunger apps such as photoshop or gaming; the laptop stop charging!

I plugged in my father's power adapter with output of 20V - 4.6 A and it works well, but the charging is still slow.

Well, can't complain much since i bought it second hand. Must be the seller also didn't notice the problem. Have to take alook at low yatt for a new power adapter then!

let say i add 4gb 1333mhz to my stock 4gb 1600mhz, the speed will be throttled to 1333mhz right? but the difference is not that significance?

any seller of good ram for my y480?

Ok. I just installed new 4gb eam abd done a quick windows experience index. However, the bottleneck was the graphic for aero which was only scored 5.9 . This is weird as I think the test use the intel graphic instead of nty gt 650m.

1. How do I make sure it choose the graphic card?
2. When I use hdmi cable to y tv, the same thing happen where it won't go full hd by not using graphic card as well..

Note that Ive upgraded to the latest driver.. using win 7 64bit.

Thanks

Hey thanks for your tips! I've got the right numbers now. Time to grab some msata next!

What's the power of the y480 power adapter?
19V - 6.15A but how many watt? Because i bought a local one, and putting hyperdynamic (after high performance one) in power management for hardcore gaming make the load too high and it stopped charging. Lol

Another question, will it effect anything on my laptop performance if I mix the ram as such :

1. Stock 4gb 1600mhz 1.35v
2. Kingston 4gb 1600mhz 1.5v

Thanks

ok thanks. i'm not sure it's the stock either, but using cpu-z to check the manufacturer, the box is blank and part number is SHARETRONIC. no idea what it means.
anyway, the voltage stated is 1.28, not 1.35v ...

mine too.. i just reformat the laptop and now i'm in trouble to install the windows... luckily my university is giving out a free copy of win 7

just bought msata crucial m4 128gb. installed win7 and boot in 25 seconds. the performance also is noticably increased ( such as opening photoshop / office word ). Games all transferred to stock hdd.

Satisfaction level = 9/10 !

mine is migrated by using paragon. maybe that's why.. 25 sconds..

did you make it as a bootable usb? using any software.. such as

Rufus : http://rufus.akeo.ie/
hiren : http://www.hiren.info/pages/bootcd-on-usb-disk

and make sure he install the correct RAM.. let say if yours is already 1600mhz.. check if you got also 1600mhz not 1333mhz. Some people sometime miss this.

hi. what do you mean by lag? maybe you're on power save mode?
Anyway, upgrading to SSD is really worth it. I just did. Lol.
Can't recommend you the brand tho, as i also didn't familiar with this.. But people keep on saying to choose marvell than sandforce controller.. so i choose Crucial Brand.

Mine is mSata crucial m4 128gb SSD. Price is rm340. It is smaller ssd i think? >.<

download this : http://www.cpuid.com/downloads/cpu-z/1.63-setup-en.exe

then under SPD tab, check the max bandwith (it should write 800mhz)

hi.. mine is mSata. there's a special slot beneath my laptop (i'm sure yours as well) for it. Doesn't have to replace the HDD. But if you buy other SSD which isn't mSata SSD, then you have to replace it.. You can check the item from the seller under my signature. Many SSD to choose from. You can even ask him for suggestion. He's a nice seller with very fast shipping.

Yes. the HDD stay at the same place. Only add mSata inside.

You can choose to install it with fresh windows or copy the current OS from HDD.

Here's a blog showed the step to do it if you want to copy the current OS.
(It is for y480 but i think the method is the same with any SSD).

Can't say which is better since i don't own both. Maybe someone else can answer that. But for me it's fast enough already. Opening micrsft word takes only 1 second. XD

ok. i'm planning to upgrade to w8. I've question regarding the drivers for w8 for lenovo y480.

THere's no atheros wireless Lan driver for it? i checked for it at http://support.lenovo.com/en_US/research/h...&DocID=HT073632 but only for win7. which 1 should i select then?
