唉，联想为什么自己不出一款高分屏的呢？出的话我早买了

这么快就没下文了

早日成功！！期待...

其实 x220本身有外接 displayport接口,在底座接口和左边都有焊盘,可以从dp口飞线到fhd的lcd的edp接口,
要启用了dp的接口如果内置的lvds没有了信号,背光亮度和键盘灯也失去了作用.
解决方法就是修改bios,让displayport和lvds 双屏同样图像显示 full 1920x1080 hd的图像
目前bios只能同显 1366*768. 让bios能够输出FHD的LVDS信号就可以了.
解释下 lvds 虽然没有接屏幕但是双屏同样图像显示就不会缺像素了

这个要支持啊。

有没有T430可换的 1080P屏幕？

LZ真是厉害啊。

期待。

不知是否需要刷BIOS

还没有什么进展？

Support you, Good luck.

looking forward to your modification! I'm sick of my screen right now although it's an IPS one.

如果真的有那么高分辨率的IPS屏，就准备入手一块

神器啊，这个可以用在x230上吗？
尺寸也是12.5的

X230's BIOS is a editable. ( you can't only flash the modified rom image by winphlash, Modified X230 bios can be flashed by rom writer). A few days ago , I have ordered dell xps duo 12 LCD ( LP125WF1-SPA1) from united kingdom for X230 FHD Modification. If I succeed to install 12.5 FHD on my X230, I will post it.

waiting for your good news
BTW do you have any idea about putting QX9300 on T61?

It is impossible to install QX9300 on t61p ,because of north bridge chipset.

Check out this thread http://forum.notebookreview.com/ ... ge-part-2-a-58.html
someone successfully run one core of Q9200 on HP HDX9000 (PM965 chipset). And later he managed to run two cores of QX9300

From what I've observed, CPU power supply is one of the "many" problems.... W700, M4400 have 3 large CPU chokes, in comparison to three much smaller ones on T400/T500/R400/R500/W500, and only 2 on T61. Also on the datasheet even Q9000 at idle requires a larger current than T9900

I think maybe a pin mod for reducing VID by 0.2V (shortcircuiting VID[4] and VCC) will help. But I don't have the condition to test this.

Someone else has also compared schematics from T(W)500 | W700 HP hdx18 and found some differenses in dual core and quad core designs. In W700 lenovo used 2 resistors in vcore feedback scheme of processor voltage regulator (it can be done on W500). HP and lenovo use some hacks to make work second core thermosensor (THRMDA_2 THRMDC_2) and debug lines (BPM_2, TDI_M, TDO_M). Some of them can be reaped out;) strange resistr in CPU clock schematicks.

But things with GTLREF_2 and GTLREF_CONTROL are vague. GTLREF_CONTROL pin F8 and soldered to Vss on dual core mainboard. Also BR1 and BPM_2[3] are soldered to Vss and Vcc instead of resrved points.
How can this things work together?

Also is there any possibility of putting a C2Q on W500? And what of T61's NB chipset is stopping it for the quad cores?

Looking forward to your answer and your good news on X220 FHD mod

非常期待结果啊
